Dobot MG400 Review: Price, Specs & Best Uses

Dobot MG400: Quick Buyer Verdict

The MG400 should be evaluated as a compact four-axis automation platform, not as a miniature replacement for every industrial robot. It works best when the process is physically small, the part is light, the required poses are simple and the buyer values easy deployment more than maximum payload or flexibility.

Pros

• Very small footprint with controller integrated into the base.
• Low entry price for an industrial-style programmable robot arm.
• Simple hand-guiding and graphical programming for quick prototypes.
• Useful industrial interfaces for PLCs, sensors, conveyors and end effectors.
• Good published repeatability for lightweight bench automation.
• Supports PC, tablet, scripting and secondary development workflows.
• Easy to relocate when production layouts or training exercises change.

Cons

• Only four axes, so the tool cannot freely tilt and rotate in three-dimensional space.
• Payload is low and official documents are inconsistent between 500 g and a 750 g maximum claim.
• The end effector, bracket, tubing and workpiece all consume the available payload.
• IP20 protection is unsuitable for dust, spray, washdown and many factory environments without additional protection.
• Collision detection does not automatically make every application safe or fence-free.
• No published standard cycle-time figure makes application testing essential.
• Support quality, included accessories and commercial terms vary by distributor and region.

Our recommendation: shortlist the MG400 when the task is top-down, compact and comfortably below 500 g including the complete tooling. Run a payload-and-cycle test before purchase, and compare the Dobot MG400 listing with larger robotic arms if the process may grow.

How Much Does the Dobot MG400 Cost in 2026?

A realistic indicative price for the Dobot MG400 robot arm is approximately US$3,700, but Dobot does not publish one universal global list price. Regional distributors may quote different prices depending on currency, taxes, shipping, warranty, training, software package and what is included with the robot.

The arm price is only the first layer. A production-ready system may also require a gripper or suction tool, mounting plate, fixtures, sensors, machine interface, emergency stop, guarding, vision, conveyor tracking, programming and commissioning. For a simple laboratory setup, these additions may remain modest. For a validated production cell, integration can become the largest part of the budget.

The correct way to compare price

Do not compare a bare MG400 with a fully integrated competitor cell. Ask each supplier to quote the same finished task: the same cycle time, part, gripper, safety concept, fixtures, acceptance test, warranty and support. A cheaper arm can become the more expensive solution if it needs substantial engineering to compensate for limited payload or motion.

For current pricing and package details, review the MG400 product page on Anton Robots and request a configuration matched to the application.

What Is the Dobot MG400?

The Dobot MG400 is a compact four-axis desktop robot arm designed for light industrial automation, laboratories, education and small-batch production. The controller is integrated into the base, so the system does not require the separate floor-standing control cabinet commonly associated with larger industrial robots.

Dobot positions the MG400 as a desktop-grade collaborative robot. It includes collision detection and hand-guiding, and it can be programmed through DobotStudio Pro, the CRStudio mobile application, graphical blocks, Lua scripts and remote interfaces. The robot is intended to carry a small end effector and move lightweight parts within a 440 mm working radius.

What the MG400 is

• A compact robot for repetitive bench-level motion.
• A practical entry point for small manufacturers exploring automation.
• A programmable research and teaching platform with industrial-style interfaces.
• A suitable base for small pick-and-place, testing, inspection, dispensing and loading cells.
• A robot that can be redeployed more easily than many full-size industrial systems.

What the MG400 is not

• It is not a six-axis cobot and cannot orient a tool freely around a component.
• It is not designed for heavy payloads or wide production cells.
• It is not protected for washdown, heavy dust or outdoor use.
• It is not automatically safe without a system-level risk assessment.
• It is not a complete automation solution until the tooling, fixtures, controls and process are engineered.
• It is not the same product as the education-focused Dobot Magician, even though both are compact desktop arms.

Buyers comparing the broader category can explore pick-and-place robots and assembly robots before selecting a model.

Dobot MG400 Specifications

The following table combines Dobot’s current product page with the MG400 V1.7 user guide dated 16 November 2023. Where the sources differ, the discrepancy is shown rather than silently choosing the more favourable number.

The payload discrepancy matters

Dobot’s current marketing page states “500 g (Max. 750 g),” while the V1.7 user guide lists a maximum load of 500 g. This may reflect a marketing distinction, a revision difference or operation under restricted load-centre conditions. A buyer should not design a production process around 750 g without written confirmation for the exact robot revision, pose, speed and centre of gravity.

The safest initial assumption is that 500 g is the usable design ceiling until the supplier validates otherwise. For robust production, the normal operating payload should remain below the absolute limit and retain margin for acceleration, cable forces, part variation and future tooling changes.

Four-Axis Design and Workspace

The MG400’s four-axis architecture is central to both its value and its limitations. It can position a tool in X, Y and Z and rotate it around the vertical axis. This is ideal for many top-down tasks because the robot does not need the cost, weight and programming complexity of a six-axis wrist.

Tasks that fit four axes well

• Moving parts between horizontal trays and fixtures.
• Loading samples into test equipment with front or top access.
• Placing components onto a PCB or assembly nest.
• Dispensing adhesive along paths where the nozzle remains vertical.
• Sorting products by position, colour or inspection result.
• Transferring parts to and from a compact conveyor.

What four axes cannot do

A four-axis robot cannot freely roll, pitch and yaw the tool. It cannot easily approach a feature from an arbitrary angle, tilt a camera around a three-dimensional object, insert a connector at a complex orientation or reach around obstacles like a six-axis cobot.

This does not mean the MG400 is inferior; it means the process must match its kinematics. A simple four-axis robot can be faster to teach and easier to validate when every operation is performed from above. It becomes the wrong machine when the fixture must compensate for missing wrist motion.

Workspace planning

The published 440 mm working radius is not a promise that every point inside a 440 mm circle is reachable with every tool angle. Joint limits, the central exclusion region, vertical travel, fixture height and tool geometry shape the real envelope. The end effector must also clear the robot links, neighbouring equipment and part fixtures throughout the complete motion.

Before purchase, build the cell in CAD or use the supplier’s simulation tools. Check every pick, place, approach, retreat and recovery position—not only the nominal production points.

Payload and Reach in Real Applications

Payload is the MG400’s most important purchasing constraint. The payload figure includes everything mounted at the flange: gripper, adapter plate, screws, sensors, pneumatic fittings, cables and the workpiece. A 300 g electric gripper carrying a 250 g part already reaches 550 g before adding a bracket or cable load.

Payload is not just mass

The MG400 user guide states that load capacity decreases as the centre of mass moves farther from the flange. A long gripper holding a light object can therefore create a more demanding load than a heavier compact tool. Acceleration, direction changes and emergency stops also generate dynamic forces that are not visible in the static weight figure.

For reliable operation, the integrator should calculate:

• Total tool-and-part mass.
• Centre-of-mass distance from the flange.
• Maximum acceleration and deceleration.
• Cable, hose and vacuum-line forces.
• Worst-case part tolerance and misalignment.
• Required safety margin for continuous operation.

How to use the 440 mm reach correctly

A compact reach is an advantage when the cell itself is compact. Shorter arms generally mean lower inertia, less floor or bench space and fewer opportunities for the robot to interfere with surrounding equipment. The MG400 can sit close to trays, test fixtures or a small conveyor and perform repeated motions without a separate controller cabinet.

The same reach becomes restrictive when loading a deep machine, serving several distant stations or working around large guards. Moving the robot to the centre of the process can help, but this may make maintenance access difficult. A linear rail is theoretically possible in custom engineering, yet it undermines the MG400’s simplicity and may make a larger robot more economical.

Practical payload rule

Design the application around the rated 500 g figure, not the most optimistic marketing number. Keep normal production below the limit, then test the heaviest part at the fastest intended motion and longest extension. A successful ten-minute demonstration is not enough; the cell should complete an extended acceptance run without alarms, drift, excessive vibration or dropped parts.

Speed, Repeatability and Process Accuracy

Dobot publishes a maximum joint speed of 300°/s on all four axes and ±0.05 mm repeatability. These figures are useful, but neither directly answers the buyer’s real question: how many acceptable parts can the completed cell produce per hour?

Joint speed is not cycle time

A maximum joint-speed specification does not include approach moves, gripper actuation, vacuum confirmation, machine handshake, vision processing, settling time or safety-limited motion. The MG400 product page does not publish a standard pick-and-place cycle time under a defined test, so suppliers should demonstrate the exact process.

A realistic cycle study should include:

1. Part detection or presentation.
2. Approach to the pick point.
3. Grip and confirmation.
4. Transfer with the real payload.
5. Placement, release and verification.
6. Return or movement to the next task.
7. Retries, faults and normal production variation.

Repeatability is not absolute accuracy

The ±0.05 mm figure describes the robot’s ability to return to a previously taught position under specified conditions. It does not mean the tool will automatically be within 0.05 mm of a CAD coordinate anywhere in the workspace.

Total process accuracy also depends on:

• Fixture tolerances and movement.
• Tool-centre-point calibration.
• Part presentation.
• Gripper compliance and jaw variation.
• Camera calibration if vision is used.
• Temperature and mechanical loading.
• Backlash, wear and collision history.

For tasks such as connector insertion, micro-assembly or precision measurement, validate the complete process capability rather than relying on robot repeatability alone.

Vibration suppression

Dobot states that its vibration-suppression algorithm improves multi-joint motion stability time by 60% and reduces residual vibration by 70%. These are manufacturer claims rather than a universal performance guarantee. The real benefit should be measured with the selected payload, path and speed, especially for dispensing or camera-based inspection where motion settling affects quality.

Programming, Software and Integration

The MG400 offers a broad set of control options for a robot in this price class. Beginners can physically guide the arm and record points, while experienced developers can use scripts, industrial communication and software interfaces.

Drag-to-teach

A button on the forearm enables hand-guiding when the robot is powered and in the correct state. The operator can move the arm to a desired point and save that position. This is useful for straightforward pick, place and waypoint teaching, although a complete application still needs logic for grippers, sensors, errors and machine states.

DobotStudio Pro and CRStudio

DobotStudio Pro is the primary Windows environment, while CRStudio supports compatible Android tablets and iPads. The V1.7 guide lists Windows 7, 10 and 11 for the PC software and notes that wireless control requires a Wi-Fi module.

The software supports graphical programming and scripting. Dobot’s current download centre lists DobotStudio Pro 2.8.3.0, released in December 2024, with MG400-related improvements and stability fixes. Buyers should confirm the supported firmware, operating system and software version before standardising a production deployment.

Graphical programming and Lua

Blockly-style programming lowers the barrier for technicians and students by representing logic as visual blocks. Lua scripting offers more control for loops, variables, calculations and custom application logic. The best production approach depends on who will maintain the cell: a simple visual program can be easier to support, while a well-documented script may scale better for complex behaviour.

Remote development and APIs

Dobot provides secondary-development resources based on TCP/IP and has published SDK support for Java, C++, C#, Python, ROS, MATLAB, LabVIEW and Android across the MG400/M1 Pro platform. This makes the MG400 attractive for research, test automation and custom supervisory software.

API availability is not the same as turnkey integration. Before committing, verify:

• Which commands are supported by the exact firmware.
• Whether the API can recover safely from alarms and emergency stops.
• How connection loss is handled.
• Whether sample code is maintained.
• What support the distributor provides for custom development.

Industrial interfaces

The robot includes 16 digital inputs and 16 digital outputs at the base, plus two inputs and two outputs at the tool. The V1.7 guide also lists two Ethernet ports, two USB 2.0 ports and an ABZ incremental encoder input for applications such as conveyor tracking.

The base I/O uses an internal 24 V supply. Dobot specifies a total output-current limit of 2 A and a per-channel limit of 500 mA. External relays or interface hardware may therefore be required for higher-power devices.

PLC and Modbus integration

TCP/IP and Modbus TCP allow the MG400 to exchange commands and status with external equipment. A robust production handshake should define ready, busy, complete, fault, reset, part-present and safe-state signals. Avoid controlling a production process through an improvised sequence of delays when explicit machine states are available.

End Effectors, Vision and Accessories

The MG400 becomes useful only when paired with the correct tool and part-presentation system. Dobot’s ecosystem includes vacuum and electric gripping options, vision components, conveyors, feeders and training systems, while third-party tools may be integrated through mechanical, pneumatic, electrical and software interfaces.

Tool weight can decide the project

Many compact industrial grippers weigh several hundred grams before adapters are added. The MG400’s low payload means the buyer should select the end effector before finalising the robot. A lighter vacuum tool may make a task viable where a conventional parallel gripper leaves insufficient payload margin.

Integrated pneumatic routing

The user guide describes a 4 mm air connection between the base and forearm for supplying pneumatic tooling. This can simplify routing, but the integrator still needs to specify the air source, valves, filtration, pressure and failure response.

Vision is useful but not automatic

A camera can reduce fixture complexity and handle variable part positions, but it adds calibration, lighting and software work. For a predictable tray or nest, a simple mechanical fixture may be cheaper and more reliable than vision. Use vision when it solves a real variation problem, not because it makes the demonstration more impressive.

Safety, IP Rating and Operating Environment

The MG400 is marketed as collaborative and includes collision detection, but the complete application must still be risk assessed. Dobot’s V1.7 user guide states that the robot’s collaborative mechanisms are intended only for non-hazardous applications after an application-specific risk assessment. It also places responsibility for complete-system safety on the integrator.

Collision detection does not guarantee a fence-free cell

Dobot has published a collision-force threshold claim below 12 N in product launch material. That does not prove that every MG400 application can operate safely beside people. A sharp tool, hot nozzle, fragile component, pinch point, pneumatic gripper or moving fixture may create hazards even when the arm itself stops after contact.

The safety concept must consider:

• Robot speed, payload and stopping distance.
• Crushing and trapping points around fixtures.
• Sharp, hot or powered end effectors.
• Dropped parts after loss of power or vacuum.
• Unexpected start-up and remote commands.
• Access during teaching, maintenance and fault recovery.
• Other machines operating in the same cell.

Depending on the risk assessment, the system may need guarding, interlocked doors, safety scanners, reduced-speed modes, safe separation or other measures. The phrase “collaborative robot” describes a capability, not the safety status of the finished application.

IP20 protection

Dobot’s FAQ lists the MG400 as IP20. In practical terms, it has basic protection against finger access to hazardous parts but no meaningful protection against water. It should be kept away from coolant, washdown, rain, conductive dust and uncontrolled contamination.

A surrounding enclosure can protect the robot, but it must also manage heat, ventilation, cable access and maintenance. In a dirty or wet process, buying a robot designed for that environment may be more reliable than engineering protection around the MG400.

Temperature and installation

The published working temperature is 0–40°C, with indoor tabletop installation and an operating-altitude limit of 1,000 m. The base must be securely fixed to a stable surface; the V1.7 guide specifies four M5 mounting bolts and emphasises that installation stiffness affects operating stability.

Prohibited and high-risk uses

The user guide identifies potentially explosive environments, life-critical applications, use before risk assessment and operation beyond stated specifications as impermissible misuse. The MG400 should not be selected for ATEX or IECEx zones, medical life-support processes or any application where a fault could create unacceptable harm without independent protective systems.

Standards and certificates

The V1.7 guide references EN ISO 10218-1:2011, EN 60204-1:2018 and EN ISO 12100:2010, together with industrial EMC standards. Its certification appendix includes collaborative-robot, reliability, FCC, CE machinery, CE EMC, RoHS, RCM and KCs documentation. Procurement teams should request the actual declarations and certificates for the exact model, serial-number range and destination market rather than relying only on a manual summary.

Real-World MG400 Results: What Published Deployments Show

Dobot has published several MG400 case studies across electronics, machine loading, dispensing and education. These examples show plausible applications, but the performance figures are manufacturer-published rather than independent controlled trials. They should be treated as evidence of what a well-engineered cell may achieve, not a guaranteed result.

What the strongest examples have in common

The successful applications are physically constrained. Parts are small, tooling is light, motions are repeated and the robot serves nearby fixtures. None depends on the MG400 behaving like a general-purpose six-axis cobot. The robot is effective because the process has been simplified around its strengths.

The case studies also reinforce a key buying principle: prove one complete cell before scaling. A low robot price makes it tempting to purchase several units immediately, but the real risk sits in part feeding, tooling, software and process reliability.

Best Dobot MG400 Use Cases

1. Small-part pick and place

Best overall use case. The MG400 is well suited to moving lightweight components between trays, nests, conveyors and inspection stations. The task should use top-down approaches and keep the combined gripper-and-part mass comfortably below the payload limit.

2. Electronics loading and unloading

PCBs, chips, housings and small electronic components often fit the MG400’s reach and payload. The robot can load test fixtures, transfer parts between process steps and sort results. ESD requirements, delicate gripping and precise fixture design need separate validation.

3. Laboratory automation

The arm can transfer samples, press buttons, load instruments and repeat experimental sequences. Its small footprint and software interfaces are attractive for research teams, although laboratory safety, contamination control and instrument compatibility remain application-specific.

4. Test automation

The MG400 can repeatedly insert a product into a test station, operate a fixture or move a sensor to defined positions. This is especially valuable when a test is repetitive, slow and difficult to justify with a larger industrial robot.

5. Light assembly

Simple placement, stacking, component insertion and screw presentation may fit the robot. Contact-rich assembly can require compliance, force sensing or precision fixtures that are not part of the base MG400 specification.

6. Adhesive and liquid dispensing

The robot’s repeatability and four-axis motion suit planar dispensing paths. The process must control material flow, start-stop behaviour, nozzle height, cleaning and curing. A robot can repeat a bad dispensing process very consistently, so material engineering matters.

7. Compact machine tending

The MG400 can load very small machines or benchtop process equipment when access is close and unobstructed. It is not a natural fit for deep CNC machines, heavy doors or parts approaching its payload limit. See larger machine-tending robots when reach or payload is uncertain.

8. Vision-guided sorting

With a suitable camera and lighting, the robot can locate, classify and sort small parts. The cycle time must include image capture and processing, and the vision system must be validated against all expected colours, reflections and orientations.

9. Education and workforce training

The MG400 offers a useful bridge between hobby robots and full industrial systems. Students can learn coordinate systems, I/O, PLC communication, motion planning, machine vision and safety on a compact platform. Buyers focused primarily on classroom affordability should also compare educational robots and the Dobot Magician range.

10. Robotics and AI research

Python, ROS and other development options make the arm useful for perception, tactile sensing, reinforcement learning and human-robot interaction experiments. Researchers should confirm command rates, latency, state feedback and firmware behaviour before selecting it for control-intensive work.

When the Dobot MG400 Is Not the Right Robot

The MG400 is attractive because it is compact and inexpensive, but those qualities should not override the physical requirements of the application.

• Payload near or above 500 g: tool weight and load-centre effects leave too little margin.
• Complex tool orientation: choose a six-axis robot when the tool must tilt, roll or approach from different angles.
• Large work envelope: 440 mm is insufficient for wide trays, multiple distant stations or deep machines.
• Wet or dusty production: IP20 is not suitable for washdown, coolant spray or substantial contamination.
• High-speed industrial throughput: compare dedicated SCARA robots with published cycle times and higher payload.
• Welding or heavy dispensing: the payload, process hazards and environmental exposure exceed the natural use case.
• Palletizing: the reach and payload are far below normal palletizing requirements.
• Explosive environments: the user guide prohibits use in potentially explosive atmospheres.
• Life-critical applications: the robot is not intended for processes where failure could directly endanger life.
• Unstructured general manipulation: four axes, limited payload and basic sensing do not make it a general-purpose AI arm.
• No internal owner: even a low-cost robot becomes poor value when nobody maintains tooling, programs and production data.

When the task needs more reach, payload and six-axis flexibility, compare the Dobot CR5A or other industrial cobots instead of forcing the MG400 into the wrong process.

Dobot MG400 vs M1 Pro, Meca500, UFACTORY Lite 6 and Epson T3-B

The best alternative depends on whether the buyer values low cost, six-axis flexibility, precision, payload or industrial throughput. Specifications below come from current manufacturer documentation where available; configurations and test methods differ.

Which one should you choose?

• Choose the MG400 for low-cost, compact, top-down automation with a light tool and simple process.
• Choose the M1 Pro when the process still suits four axes but needs more payload, precision and industrial headroom.
• Choose the Meca500 when six-axis orientation and extremely high repeatability matter more than entry price or reach.
• Choose the UFACTORY Lite 6 for flexible six-axis education and research where industrial repeatability is less critical.
• Choose the Epson T3-B for higher-throughput production, larger payloads and a mature SCARA automation environment.

Use the Anton Robots comparison tool to compare the MG400 with other models side by side.

Is the Dobot MG400 Worth It?

The MG400 is worth it when a small, repetitive process can be automated without fighting the robot’s 500 g payload, four-axis motion and 440 mm reach. Its low entry price can produce a short payback period, but only when part presentation, tooling and process reliability remain simple.

Build the business case from the current process

A basic annual-value model is:

Annual benefit = labour time saved + increased output + avoided defects + improved equipment utilisation − annual operating cost.

Then calculate:

Payback period = total implementation cost ÷ monthly net benefit.

Costs to include

• Robot arm and delivery.
• Gripper, vacuum system or custom tool.
• Fixtures, trays, conveyor or feeder.
• Vision, sensors and lighting.
• PLC, relays, safety equipment and machine interfaces.
• Mechanical and electrical engineering.
• Programming, testing and documentation.
• Training, support, maintenance and production changes.
• Downtime during installation and debugging.

Benefits to validate

• Operator minutes removed from each cycle.
• Extra machine hours created by unattended loading.
• Improved consistency in placement or dispensing.
• Reduced ergonomic exposure from repetitive handling.
• More frequent or standardised testing.
• Ability to run small batches without expensive fixed automation.

Example decision logic

The MG400 is compelling when one operator currently moves a small part between two nearby stations thousands of times per month. It is less compelling when the process runs only occasionally, parts arrive randomly, the gripper is heavy and the robot needs custom guarding, machine modifications and complex vision.

Minimum pilot criteria

Before buying several units, prove:

1. The heaviest real payload can be handled with margin.
2. The complete cycle meets the required throughput.
3. Part pickup and release are reliable.
4. The system recovers from common faults.
5. The process remains stable over an extended production run.
6. The team can maintain the program and tooling.
7. The financial payback remains attractive after all integration costs.

Dobot MG400 Buying Checklist

1. Define one exact task. Document the current process, part, cycle time, annual volume and reason for automation.
2. Weigh the complete payload. Include gripper, adapter, fittings, cables and the heaviest workpiece.
3. Calculate the load centre. Confirm the supplier accepts the tool’s centre of gravity at the required speed and reach.
4. Confirm four-axis suitability. Draw every required tool orientation and approach direction.
5. Map the workspace. Validate all pick, place, approach, retreat, home and recovery positions.
6. Measure the real cycle. Include gripping, sensing, communication, settling and machine wait time.
7. Select part presentation. Decide whether trays, fixtures, a conveyor, feeder or vision will locate each part.
8. Choose the end effector first. Avoid discovering after purchase that the preferred gripper consumes most of the payload.
9. Design the machine handshake. Define every ready, busy, complete, fault, reset and interlock signal.
10. Complete a risk assessment. Evaluate the full cell, not only the robot arm.
11. Check the environment. Confirm IP20 and 0–40°C are suitable for the installation area.
12. Verify software compatibility. Confirm firmware, DobotStudio Pro version, API and operating-system support.
13. Request a sample program. Test the programming method the internal team will actually maintain.
14. Run an extended acceptance test. Use production parts, realistic variation and the intended operating speed.
15. Request commercial details. Confirm warranty, support response, spare parts, training, lead time and what is included.
16. Calculate three-year TCO. Include integration, support and likely process changes—not just the arm.

Pro tip: place the real gripper and heaviest part on a scale before requesting a quote. For the MG400, a few hundred grams can change the robot decision completely.

How to Buy the Dobot MG400

The MG400 is available through Dobot and regional distributors. The quality of the purchase depends less on finding the lowest arm price and more on obtaining a package that includes the correct tooling, documentation, support and acceptance test.

Prepare this information before requesting a quote

• Part dimensions, mass, material and surface condition.
• Required pick and place positions.
• Target cycle time and annual volume.
• Preferred gripper or vacuum method.
• Photos, video or CAD of the workstation.
• Available power, air and network connections.
• PLC or machine communication requirements.
• Temperature, dust, liquids and other environmental conditions.
• Required safety and regulatory standards.
• Who will program, operate and maintain the system.

Questions to ask the supplier

• Is the quoted robot revision rated for 500 g or 750 g, and under what conditions?
• What payload is permitted at the proposed centre of mass and acceleration?
• Which software and firmware versions are supplied?
• Does the package include an emergency stop, mounting hardware and required cables?
• Which end effectors are tested with the MG400?
• What local integration and training support is available?
• What are the warranty exclusions and expected repair process?
• Can the supplier demonstrate the actual part and cycle before purchase?

Review the Dobot MG400 product listing, then contact Anton Robots to discuss price, availability and configuration. Buyers who are not certain that the MG400 fits can use the Find My Robot tool before committing.

Is the Dobot MG400 Still Current in 2026?

Yes. The MG400 remains listed in Dobot’s active product portfolio in 2026 as its desktop-grade industrial collaborative robot. Dobot’s current website continues to present the model for small-batch flexible production, and recent case studies show ongoing use in research and education.

No major new hardware revision is publicly identified

Dobot’s current MG400 page retains the established 440 mm reach, 500 g rated payload, 750 g maximum marketing figure and ±0.05 mm repeatability. We did not find a clearly named MG400 hardware successor or 2026 revision on the official product page. Buyers should therefore confirm the production date, hardware revision and included firmware in the quotation rather than assuming every unit is identical.

Software support remains relevant

Dobot’s download centre lists DobotStudio Pro 2.8.3.0 from December 2024 as the latest public Windows package shown for MG400 on the product page. The update notes include improved MG400 auto-identification safeguards and stability fixes. This suggests continued software maintenance, although organisations should ask Dobot for the current support roadmap before standardising a large fleet.

Recent research deployments

Dobot published MG400 case studies with Bristol Robotics Laboratory and Sabancı University in 2025. These do not prove new hardware capability, but they show that the platform remains in active use for robotics research, tactile sensing, Python-controlled experiments and automation teaching.

2026 buyer verdict: the MG400 is still a relevant low-cost desktop automation platform, but it should be purchased for its proven compact use case—not because it represents the newest generation of collaborative robotics.

Dobot MG400 FAQ

How much does the Dobot MG400 cost?

An indicative 2026 price is approximately US$3,700 for the robot arm, but regional quotations vary. A complete system costs more once the gripper, fixtures, controls, safety equipment, programming and support are included.

What is the Dobot MG400 payload?

Dobot’s current product page lists 500 g payload and a 750 g maximum, while the V1.7 user guide lists a maximum load of 500 g. Buyers should design around 500 g unless the supplier validates a higher load for the exact robot, tool, centre of gravity and motion.

Does the gripper count toward the payload?

Yes. The payload includes the end effector, adapter, fittings, sensors, cables and workpiece. This is one of the most important constraints when designing an MG400 application.

What is the Dobot MG400 reach?

The published working radius is 440 mm. The reachable area is shaped by joint limits, tool geometry and fixture height, so not every point inside a simple 440 mm circle is usable in every orientation.

How accurate is the MG400?

Dobot publishes ±0.05 mm repeatability. This describes repeated return to a taught position, not guaranteed absolute accuracy throughout the workspace. Complete process accuracy depends on tooling, calibration, fixtures, vision and the part.

Is the MG400 a cobot?

Dobot markets it as a desktop collaborative robot and it includes hand-guiding and collision detection. The completed application is collaborative only after a risk assessment shows that the robot, tool, part, fixtures and surrounding equipment can operate safely with people.

Does the MG400 need a safety fence?

Not automatically, but it may. The requirement depends on the application-specific risk assessment. Sharp tools, pinch points, high speed, hot processes, dropped parts or other machinery can require guarding or additional safety devices.

What is the MG400 IP rating?

Dobot lists the MG400 as IP20. It is intended for clean indoor use and is not protected for washdown, rain, coolant spray or substantial dust.

How many axes does the MG400 have?

It has four axes. The robot can position in X, Y and Z and rotate the tool around the vertical axis, but it cannot provide the full roll, pitch and yaw flexibility of a six-axis arm.

Can the MG400 load a CNC machine?

Only very small machines and lightweight parts that fit within its 440 mm reach and payload. Deep machine access, doors, heavy chucks and typical metal components usually require a larger six-axis machine-tending robot.

Can the MG400 do pick and place?

Yes. Lightweight pick and place between nearby trays, conveyors and fixtures is its strongest application, especially when the approach is vertical and part positions are controlled.

Can the MG400 perform assembly?

It can perform simple placement and insertion tasks, but contact-rich assembly may require compliance, force sensing, precision fixtures or a six-axis wrist. The complete process should be tested with real components.

Can the MG400 dispense glue?

Yes. Manufacturer case studies show planar gluing applications. The robot controls motion, while dispensing quality also depends on material flow, nozzle calibration, start-stop response and process cleanliness.

Does the MG400 support vision?

Yes, vision systems can be integrated for part location, inspection and sorting. The camera, lens, lighting, calibration and software are separate parts of the solution and must be engineered for the application.

Can the MG400 track a conveyor?

The user guide lists a differential ABZ encoder interface intended for conveyor tracking. Actual tracking performance depends on encoder setup, conveyor stability, software configuration, speed and the complete cell design.

How is the MG400 programmed?

It supports hand-guiding, graphical Blockly-style programming, Lua scripts, DobotStudio Pro, the CRStudio app and remote development interfaces. Dobot has also published SDK resources for languages and platforms including Python, C++, C#, Java, ROS, MATLAB and LabVIEW.

Does the MG400 have a separate controller?

No external control cabinet is required for the base robot because the controller and servo drive are integrated into the robot base. External control, safety and tool hardware may still be needed for the complete cell.

Can the MG400 run continuously?

Dobot positions it for industrial automation, but the public product page does not provide a simple continuous-duty guarantee or standard cycle-life figure. Buyers should run an extended acceptance test and clarify maintenance, duty cycle and warranty with the supplier.

What maintenance does the MG400 require?

The V1.7 guide states that overall maintenance is required every 20,000 operating hours or every four years, whichever comes first. Application conditions, collisions and tooling may create additional inspection requirements.

Can the MG400 be used outdoors?

No. The published installation is indoor tabletop use, with IP20 protection and a 0–40°C working-temperature range.

Can the MG400 be used in an explosive atmosphere?

No. The user guide identifies potentially explosive environments as impermissible misuse. Select a robot and complete system carrying the required hazardous-area certification.

What is the best alternative to the MG400?

Choose the Dobot M1 Pro for more four-axis payload and precision, the Mecademic Meca500 for compact six-axis precision, the UFACTORY Lite 6 for affordable six-axis research flexibility, or the Epson T3-B for higher-payload industrial SCARA production.

Is the Dobot MG400 worth buying?

It is worth buying when the task is compact, repetitive, top-down and comfortably within the 500 g payload. It is poor value when the process needs a larger envelope, complex orientation, harsh-environment protection or substantial custom engineering to overcome the robot’s limits.

Final Verdict: Should You Buy the Dobot MG400?

Buy or pilot the Dobot MG400 when you need an affordable, compact robot for lightweight bench automation and the complete process genuinely fits four axes, 440 mm reach and a conservative 500 g payload. Its integrated controller, hand-guiding, graphical programming, scripting and industrial I/O make it more capable than a typical educational desktop arm while remaining far more accessible than most full-size industrial robots.

The MG400’s limitations are not minor details. The low payload can be consumed by the gripper before the part is added. Four axes restrict tool orientation. IP20 confines the robot to clean indoor environments. Collision detection does not remove the need for a full risk assessment. The difference between a useful automation cell and a frustrating prototype is whether these constraints are respected from the beginning.

For the right task, the MG400 can deliver excellent value and a credible route into automation for small manufacturers, laboratories and training teams. For the wrong task, a higher-payload SCARA or six-axis cobot will be cheaper once integration, reliability and future changes are considered.

The smartest purchasing path is a process-led pilot: one real part, the final gripper, the intended cycle time, explicit safety requirements and an extended acceptance run. If the MG400 completes that test with payload margin and reliable recovery, its low price and small footprint become genuine competitive advantages.
