FAQ

Frequently asked questions

How much does the Annin Robotics AR4 MK5 cost? +

The Annin Robotics AR4 MK5 price is currently listed at around US$1,189 for the combo kit before motors, drivers, printed parts, tooling, shipping and taxes for the base DIY robot combo kit. That figure should be treated as a starting point rather than the final delivered cost because promotions, regional pricing and package contents can change. The final Annin Robotics AR4 MK5 cost can change depending on the destination country, supplier, stock, freight, taxes, import duties, controller configuration, software, tooling, warranty and local technical support. For a real project, buyers should also budget for the separate motor-and-driver package, 3D-printed covers, gripper, tool holder, controller options, assembly labour, calibration and safety equipment.

This is why an arm-only price can be misleading: two offers may use the same model name but include very different equipment and deployment work. If you are buying for engineering schools, makerspaces, laboratories, researchers and light-automation developers, the better question is what is included, what is excluded, and who is responsible for integration and support?

You can request a Annin Robotics AR4 MK5 quote through Anton Robots to compare the full package, delivery terms and support options before buying.

Where can I buy the Annin Robotics AR4 MK5? +

You can buy or request the Annin Robotics AR4 MK5 through Anton Robots. We help buyers compare robotic arms options, verify supplier information, understand what is included and decide whether the AR4 MK5 is correctly sized for the intended task. The Annin Robotics AR4 MK5 is also available through Annin Robotics and selected authorised robotics distributors or integrators, but not every offer is equivalent. Some proposals cover only the robot and basic control hardware, while others may include the combo kit, separate motors and drivers, 3D-printed components, gripper, PLC option, CAD files and community support.

Before buying, confirm the exact model, payload, reach, controller, cables, software access, end effector, mounting equipment, safety equipment, freight, taxes, warranty and after-sales support. This matters because professional buyers are purchasing an automation system, not only a mechanical arm. For engineering schools, makerspaces, laboratories, researchers and light-automation developers, choosing the correct application package and integrator is usually more important than finding the lowest displayed price.

To start, request a Annin Robotics AR4 MK5 quote and Anton Robots can help you compare price, package, delivery and support.

Where can I find a Annin Robotics AR4 MK5 for sale? +

You can find the Annin Robotics AR4 MK5 for sale through Annin Robotics, authorised robot distributors, automation integrators and specialist robot marketplaces such as Anton Robots. However, finding the model for sale is only the first step. The important part is checking whether the proposal matches the real application. A low advertised price may exclude the controller, teach pendant, software, gripper, vision, mounting base, safety equipment, integration, commissioning, training, freight, taxes or local warranty handling.

For professional buyers, the safest comparison is the total delivered and deployed cost. That means checking the exact robot version, payload including tooling, required reach, cycle time, interfaces, installation conditions, delivery date and support process. This is especially important for engineering schools, makerspaces, laboratories, researchers and light-automation developers where the robot must meet a real production target or project deadline.

If you are looking for a Annin Robotics AR4 MK5 for sale and want help comparing complete offers, contact Anton Robots before placing an order.

Can I get a quote for the Annin Robotics AR4 MK5? +

Yes. You can get a quote for the Annin Robotics AR4 MK5 through Anton Robots. A useful quote should show more than the base robot price. It should identify the exact arm, controller, operator interface, cables, software, mounting arrangement, end effector, safety equipment, shipping assumptions, warranty terms, delivery estimate and available support. It should also state whether motor package, printed components, gripper, controller hardware, build labour, calibration, safety provisions and freight are included or priced separately.

This matters because a proposal that looks cheaper at first can become more expensive once tooling, integration, freight, taxes, training and commissioning are added. Before requesting a quote, define the part weight, tool weight, required reach, cycle time, workcell layout, process and level of human access. Those details determine whether the AR4 MK5 is suitable or whether another payload or reach class would be safer.

Anton Robots can help you compare the Annin Robotics AR4 MK5 against other robotic arms and request a package based on your use case, location and deployment requirements.

What is included when you buy the Annin Robotics AR4 MK5? +

A typical Annin Robotics AR4 MK5 package may include the main machined aluminium structure, bearings, belts, pulleys, shafts, pins, fasteners and primary electrical components. The exact package varies by supplier, region and controller choice, so buyers should not assume that every quotation contains the same equipment. The application tool is one of the most important items to check. A robot arm normally needs a gripper, suction system, process tool, camera, fixture or other end effector before it can perform useful work.

Before buying the Annin Robotics AR4 MK5, ask for a clear packing list and scope of supply. Confirm whether the proposal includes:

  • AR4 MK5 combo-kit structural and hardware parts
  • Bearings, belts, pulleys, shafts, pins, and fasteners
  • Primary electrical components included by Annin Robotics
  • Separate compatible motors, drivers, and power supply
  • Software, firmware, build manual, and required printed components
  • Shipping or freight terms
  • Warranty and after-sales support

Also check what is not included, particularly integration, programming, risk assessment, guarding, fixtures, training and on-site commissioning. Two offers can both say “Annin Robotics AR4 MK5” while representing very different levels of readiness. You can request an itemised package quote through Anton Robots before buying.

What is the payload and reach of the Annin Robotics AR4 MK5? +

The Annin Robotics AR4 MK5 payload is 1.9 kg, and its maximum reach is 629 mm. Official specifications list position repeatability at 0.2 mm. These figures make the AR4 MK5 suitable for light parts, small grippers, cameras, educational tooling and prototype applications.

Payload must be calculated using the complete tool-side mass, not only the product being moved. Include the gripper or process tool, adapter plate, camera, hoses, cables and any bracket attached to the flange. The load centre, wrist orientation and motion profile can also affect usable capacity. Reach should be checked with the actual machine, fixture, pallet, conveyor or bench layout. A robot may have enough nominal reach but still be unable to approach every point with the required tool angle.

If the combined payload is close to the limit, or the workcell needs extended reach, a larger model may be more reliable. You can request robot sizing advice through Anton Robots before choosing the Annin Robotics AR4 MK5.

Can the Annin Robotics AR4 MK5 be shipped internationally? +

Yes, the Annin Robotics AR4 MK5 can generally be supplied internationally through Annin Robotics distributors and automation partners, subject to regional availability, export rules, destination-country requirements and the supplier’s territory. International delivery is more than moving the arm from one country to another. The shipment may include a robot, controller, cables, operator device, mounting hardware and accessories, sometimes in separate packages. Freight, insurance, customs clearance, import duties, VAT or GST, local electrical requirements and on-site delivery can all affect the final landed cost.

Before ordering, confirm who is responsible for customs, whether the quoted price includes freight, and whether local commissioning and warranty service are available in the destination country. For an industrial project, local technical support can be more valuable than a small saving on the robot itself.

If you need the Annin Robotics AR4 MK5 supplied internationally, request an international quote through Anton Robots so the full package and support route can be checked before purchase.

Is the Annin Robotics AR4 MK5 in stock and how long does delivery take? +

Annin Robotics AR4 MK5 stock and delivery time can change by region, controller choice, distributor inventory and current project demand. Some authorised partners may hold the robot or controller locally, while others order the system from the manufacturer after receiving a purchase order. Tooling, safety devices and custom integration normally have their own lead times.

A website listing should not be treated as proof that a complete deployable system is ready to ship. Ask the supplier to confirm the exact model, serial production status, controller, operator interface, accessories and estimated dispatch date in writing. Also check whether integration, factory acceptance testing, training and commissioning are included in the schedule. If the robot is needed for a production launch, research project, training course or customer deadline, allow contingency for freight, customs and application engineering.

You can request current Annin Robotics AR4 MK5 availability through Anton Robots before placing an order.

What warranty and support should I check before buying the Annin Robotics AR4 MK5? +

Before buying the Annin Robotics AR4 MK5, confirm the warranty period, covered components, geographic coverage, response process and who provides first-line support. Warranty terms can differ by country, distributor, controller package and whether the robot is purchased as a bare system or as part of an integrated cell. Ask who handles diagnosis, software issues, replacement parts, freight for repairs and on-site service. Also confirm whether damage caused by unsuitable tooling, collisions, incorrect installation, environmental exposure or third-party modifications is excluded.

Professional buyers should check access to spare cables, joint service, controller support, software updates and application engineering. The lowest quote is not always the lowest-risk purchase if warranty handling and local support are unclear. For engineering schools, makerspaces, laboratories, researchers and light-automation developers, downtime and delayed troubleshooting can cost more than the original price difference.

You can contact Anton Robots to compare the support scope and request written warranty terms before buying the Annin Robotics AR4 MK5.

Is the Annin Robotics AR4 MK5 worth buying? +

Yes, the Annin Robotics AR4 MK5 is worth considering when you need a hands-on open robot-arm platform for learning, research and light automation development. Its combination of machined aluminium construction, 1.9 kg payload, open build resources and a comparatively low kit price gives it a clear role within the Annin Robotics range. It is especially relevant for engineering schools, makerspaces, laboratories, researchers and light-automation developers that need a flexible robot rather than a fixed-purpose machine.

However, the AR4 MK5 is only good value when the task matches its payload, reach, repeatability, mounting and safety requirements. It should not be selected only because the model is well known or because the arm-only price looks attractive. The end effector, cycle time, fixtures, process equipment, guarding, programming and support determine whether the final system succeeds.

It is a DIY platform, not a turnkey certified cobot, and the buyer is responsible for assembly quality, commissioning and application safety. For suitable applications, the Annin Robotics AR4 MK5 can be a strong platform. For a mismatched task, a different payload class or robot type may produce better uptime and lower total cost. Compare other robotic arms on Anton Robots before choosing.

What applications is the Annin Robotics AR4 MK5 good for? +

The Annin Robotics AR4 MK5 is well suited to education, research, light pick and place, inspection prototypes, custom tooling and small automation experiments. The best applications use parts and tools that remain inside the robot’s 1.9 kg payload and 629 mm reach while allowing adequate clearance and a repeatable presentation of the work. For pick and place, check part shape, gripper weight, cycle time, fixture position and whether vision is required.

For machine tending, check the machine opening, door automation, chuck or fixture interface, communications and contamination risks. For assembly or process work, confirm force, accuracy, tool services and quality-control requirements. The robot arm alone does not create a complete application. Tooling, fixtures, sensors, software and safety controls must be designed around the real process. A short feasibility study using sample parts is often the safest way to validate the choice.

You can request an application quote through Anton Robots to compare the robot, tool and integration package.

How is the Annin Robotics AR4 MK5 programmed? +

The Annin Robotics AR4 MK5 can be programmed using Annin Robotics control software, Teensy and Arduino firmware, downloadable source resources and community-supported ROS 2 packages. The most suitable method depends on whether the buyer wants fast operator teaching, offline development, PLC integration, research access or a repeatable production workflow. For a simple cell, an integrator may create positions and logic through the manufacturer interface and connect the robot to grippers, sensors and machines. More advanced projects may use APIs, fieldbus, ROS or external software, depending on the exact controller and licences supplied.

Buyers should verify supported versions rather than assuming that every online example applies to every controller generation. Before purchase, define who will program the robot, how programs will be backed up, what training is needed and whether source access or external integration is essential. Software compatibility can be as important as payload and reach.

If programming is central to the purchase, contact Anton Robots and request confirmation of the controller, software and integration interfaces included with the Annin Robotics AR4 MK5.

Does the Annin Robotics AR4 MK5 include a controller or teach pendant? +

The Annin Robotics AR4 MK5 controller and operator interface depend on the package selected. The combo kit includes primary electrical components, but the builder must obtain the specified motors and drivers separately and assemble the complete control system.

Buyers should not assume that every quotation automatically includes the same teach pendant, emergency-stop hardware, laptop interface or software licence. Ask the supplier to identify the controller model, input power, I/O, network interfaces, cables and operator device in the scope of supply. Confirm whether a physical teach pendant is included, optional or replaced by a PC-based interface. Also check whether the package contains the required mounting, emergency-stop and safety connections. This is particularly important when comparing low online prices because a robot without the correct control equipment cannot be commissioned. For training and first-time users, the operator interface and documentation also affect the time needed to become productive.

You can request a complete controller package through Anton Robots before buying the Annin Robotics AR4 MK5.

Can the Annin Robotics AR4 MK5 work safely around people? +

The Annin Robotics AR4 MK5 is designed for collaborative robot applications, but that does not make every installation automatically safe without guarding. Safety depends on the programmed speed, payload, tool, part, workspace, trapping points and level of human access. The AR4 does not become a certified collaborative cell simply because it is small; the builder must provide emergency stopping, safe speeds, guarding or separation as required.

A risk assessment should review crushing, impact, sharp tools, hot processes, dropped parts, unexpected motion, loss of communications and access to emergency stops. The integrator may need reduced-speed zones, safety scanners, guarding, interlocks or separation even when the arm itself has safety-rated functions. The word collaborative describes a capability of the system, not a guarantee for every application. Welding, knives, heavy loads and dangerous end effectors can require additional protection.

Buyers should request the applicable safety documentation and confirm compliance with local machinery and workplace rules. Anton Robots can help you compare complete packages, but the final cell must be validated by a competent integrator and site-specific risk assessment.

Should I buy the AR4 MK5 or an older AR4 MK3 or MK4? +

The right Annin Robotics model depends on payload, reach, process and workcell layout. The Annin Robotics AR4 MK5 is positioned around 1.9 kg payload and 629 mm reach. The MK5 is the current AR4 revision. Older MK3 and MK4 systems may be upgradeable, but buyers should use MK5-specific parts, manuals and software when starting a new build. Choose the smaller or lower-payload model when the parts, tool and reach are comfortably within its limits and compactness matters.

Choose a larger model when the payload margin, working envelope, pallet height or future product range justifies it. Avoid operating permanently at the edge of the published payload or reach because real tools, cables and load centres reduce practical margin. Repeatability, mounting orientation, force sensing, controller options and safety features can also differ between series. A correct comparison should use the actual part, end effector and cell drawing rather than model names alone.

You can request model-comparison advice through Anton Robots before choosing the Annin Robotics AR4 MK5.

What else is required to build and deploy the AR4 MK5? +

A complete Annin Robotics AR4 MK5 deployment normally requires more than the robot arm. The final equipment depends on the part, process, cycle time, environment and degree of human access.

  • Build components: the Annin combo kit plus the specified motor, driver and power-supply package, printed covers and spacers, and a gripper or tool holder.
  • Commissioning: assembly tools, wiring, firmware installation, calibration, rigid mounting, fixtures, and any sensors or PLC interfaces.
  • Safety and support: controlled test area, emergency shutdown, conservative payload testing, documented maintenance, and competent supervision.

The cell may also require programming, PLC or machine communications, vision calibration, fixtures, electrical and pneumatic services, factory acceptance testing, operator training and maintenance documentation. The robot’s published payload must include the full end-effector mass, and the reach study should use the required tool orientation at every target. Ask suppliers to separate hardware, integration, freight, commissioning, training and recurring software costs so quotes can be compared fairly. A bare robot price is not a reliable estimate of a working system.
