Dobot CR3 Review: Specs, Price & CR3A Comparison

Dobot CR3: Quick Buyer Verdict

The Dobot CR3 is best understood as a small six-axis industrial collaborative arm for light automation. It is not simply an educational desktop robot scaled up for manufacturing.

With a published maximum payload of 3 kg, 620 mm working radius, 795 mm maximum reach, ±0.02 mm repeatability and 2 m/s maximum TCP speed, the CR3 targets tasks involving relatively small tools and components inside a compact work envelope.

Its 16.5 kg body also makes the robot easier to mount, relocate and integrate than many higher-payload cobots.

Pros

• Compact six-axis collaborative robot for space-constrained cells.
• Published ±0.02 mm repeatability.
• 3 kg payload is sufficient for many electronics, laboratory and small-part applications.
• 620 mm working radius can be useful for bench-mounted automation.
• Relatively light 16.5 kg robot body.
• 2 m/s published maximum TCP speed.
• Drag-to-teach and graphical programming reduce initial programming complexity.
• TCP/IP, Modbus, Wi-Fi and RS485 communication options.
• Good controller I/O provision for machine integration.
• Optional SafeSkin technology is available within the CR ecosystem.
• Large Dobot accessory and integrator ecosystem.

Cons

• 3 kg payload can be consumed quickly once the gripper, camera or dispensing hardware is included.
• 620 mm working radius is too short for many machine-tending and multi-station cells.
• IP54 protection is unsuitable for many wet, dusty or harsh industrial processes.
• SafeSkin should not be assumed to be included with every CR3 package.
• The CR3 uses an older product and controller generation than the CR3A.
• Buying new legacy-generation hardware in 2026 requires careful support and spare-parts checks.
• A collaborative robot does not make the complete application automatically safe.
• Published maximum speed should not be interpreted as the safe operating speed beside people.

Our recommendation: the CR3 remains worth considering when a distributor has a well-supported unit at an attractive total installed cost and the application genuinely fits within 3 kg and 620 mm. For a new project without a legacy constraint, request a CR3A quote at the same time before choosing the original CR3.

See the Dobot CR3 product page or compare other collaborative robots before requesting a final quotation.

How Much Does the Dobot CR3 Cost in 2026?

Dobot does not publish a universal manufacturer list price for the CR3 on its current product page. Pricing is normally obtained through Dobot or regional distributors.

Current European distributor listings show that remaining CR3 packages can sit broadly in the mid-€10,000 range before VAT, but the advertised figure should not be treated as the complete automation-cell cost. Current distributor listings differ materially by package and region.

A useful comparison therefore separates the robot-arm price from the complete installed project.

The robot price is not the cell price

A CR3 holding a simple two-finger gripper over a fixed tray is very different commercially from a CR3 with machine communication, automatic tool control, camera guidance, guarding and production acceptance requirements.

For that reason, compare suppliers using a complete scope rather than the arm alone.

A quotation should identify:

• Robot arm and controller.
• Teaching hardware.
• Robot-to-controller cable.
• End effector.
• Vision hardware.
• Mounting system.
• Safety equipment.
• Programming.
• Installation.
• Training.
• Documentation.
• Warranty.
• Travel and freight.

If you are comparing multiple brands, see the cobot price guide before treating purchase price as the primary decision factor.

What Is the Dobot CR3?

The Dobot CR3 is a six-axis collaborative robot developed for light industrial and commercial automation.

It sits at the smallest payload end of Dobot’s original CR family, which includes CR3, CR5, CR7, CR10, CR12 and CR16 models.

The CR3 weighs 16.5 kg and carries a maximum 3 kg payload. Dobot publishes a 620 mm working radius and 795 mm maximum reach.

That combination makes it particularly relevant where the robot must fit beside a compact machine, production bench or laboratory workstation.

What the CR3 is

• A six-axis collaborative robot arm.
• A light-payload automation platform.
• A programmable industrial robot rather than a fixed-purpose machine.
• A platform for grippers, vacuum tooling, dispensing equipment, cameras and other end effectors.
• A robot that can exchange data with other automation equipment.
• A relatively compact alternative to larger industrial robot arms.

What the CR3 is not

• It is not a complete automation cell by itself.
• It is not automatically safe simply because it is marketed as collaborative.
• It is not a 3 kg parts-handling robot after attaching a 1 kg gripper—the tool weight also consumes payload.
• It is not designed for large work envelopes.
• It is not a washdown robot based on its published IP54 arm rating.
• It is not Dobot’s newest 3 kg cobot generation.

If you are still deciding whether a collaborative arm is the correct category, read what a cobot is, compare current cobots or browse other six-axis robot arms.

Dobot CR3 vs CR3A: Which One Should You Buy?

This is the most important comparison for a CR3 buyer in 2026.

Dobot launched the CRA Series in September 2023 as a new-generation collaborative-robot family. Launch material described improvements including upgraded reducers, faster cycle performance, electromagnetic braking and a redesigned controller/software architecture.

The important point is that CR3A is not a larger robot replacing the CR3 with different payload and reach. The two remain very close in their headline mechanical specifications.

The current published specifications confirm that the basic payload, reach, body weight and repeatability remain almost unchanged, while CR3A increases the published maximum speed of several joints and extends the operating-temperature range.

Choose the original CR3 when:

• You already operate CR-Series equipment.
• Your software and tooling are validated around the CR platform.
• A supported CR3 is available at a materially lower total cost.
• The supplier can provide long-term parts and service support.
• The application does not benefit from the newer controller generation.

Choose the CR3A when:

• You are building a completely new automation cell.
• The price difference is relatively small.
• You want Dobot’s newer control and development platform.
• You expect the installation to remain in production for many years.
• Future software, accessories and support matter more than acquiring the cheapest available arm.

Buyer rule: if a supplier quotes a new CR3 in 2026, ask for a CR3A alternative on the same scope before placing the order.

Dobot CR3 Specifications

The following figures reflect Dobot’s currently published CR3 specification.

Dobot also lists an optional higher-protection control-box configuration on the CR3 product page. The exact enclosure delivered should be confirmed on the quotation rather than inferred from the robot arm’s IP54 rating.

620 mm working radius vs 795 mm maximum reach

This specification deserves attention because Dobot publishes both values.

Do not design the cell simply by drawing a 795 mm circle around the robot.

A robot’s usable work envelope depends on its joint geometry, tool orientation, mounting position, singularities, machine obstructions and required approach direction.

Use Dobot’s working-range drawing or a simulation model to check whether the required TCP pose is genuinely reachable.

This matters particularly for:

• Reaching inside CNC machines.
• Accessing deep trays.
• Moving between two fixtures.
• Orientating screwdrivers or dispensing nozzles.
• Approaching components from below or behind.

A point being geometrically reachable does not guarantee that the robot can reach it with the required tool orientation.

Payload, Reach and Real-World Performance

The CR3’s defining limitation is its 3 kg maximum payload.

That sounds straightforward, but payload calculations for robot applications should include the complete load at the flange.

For example:

That apparently light 1.4 kg workpiece has already consumed most of the robot’s available payload once the tooling is included.

Payload is more than mass

Buyers should also calculate:

• Tool centre of gravity.
• Workpiece centre of gravity.
• Moment created by long tooling.
• Dynamic loads during acceleration.
• Cables and hoses attached to the tool.
• Required orientation at the worst point in the cycle.

The correct question is therefore not:

Does my component weigh less than 3 kg?

It is:

Can the CR3 safely move my complete end-of-arm tooling and component through the required trajectory at the required acceleration?

How accurate is the Dobot CR3?

Dobot publishes repeatability of ±0.02 mm.

Repeatability describes how closely the robot can return to a previously taught position under specified conditions.

It does not mean the absolute TCP position will always be within 0.02 mm of a CAD coordinate.

Real application accuracy can also be affected by:

• Base calibration.
• Tool-centre-point calibration.
• Fixture tolerances.
• Workpiece variation.
• Camera calibration.
• Robot loading.
• Temperature.
• Mounting rigidity.

For assembly, insertion or metrology-sensitive work, test the complete process rather than approving the robot based on repeatability alone.

Is 2 m/s fast?

The published maximum TCP speed is 2 m/s.

That is enough for many light automation tasks, but maximum robot speed is not the same as application throughput.

Cycle time may be constrained by:

• Acceleration and deceleration.
• Travel distance.
• Collision-detection settings.
• Human proximity.
• Gripper opening and closing time.
• Machine cycle time.
• Vision processing.
• Process dwell time.

If throughput matters, ask the integrator to simulate or physically demonstrate the entire cycle.

Dobot CR3 Programming, Software and Integration

Ease of programming is one of the CR family’s strongest selling points.

Dobot supports graphical programming, scripting and drag-to-teach workflows. The company also describes programming through computers and mobile devices.

Drag-to-teach

For straightforward applications, the operator can physically guide the robot through positions and record waypoints.

This is particularly useful for:

• Pick-and-place positions.
• Machine loading locations.
• Simple inspection points.
• Dispensing trajectories.
• Basic demonstrations.

Drag teaching can shorten commissioning, but a reliable production program still needs correct coordinate systems, tool data, logic, error recovery and safety behaviour.

DobotStudio Pro

DobotStudio Pro is Dobot’s PC programming environment for industrial robot families including CR and Nova.

It provides a more structured programming workflow for users building production applications.

Typical tasks include:

• Teaching positions.
• Creating motion sequences.
• Configuring I/O.
• Managing variables and logic.
• Monitoring robot status.
• Diagnosing alarms.

Can you program the CR3 with Python?

Yes, subject to controller and firmware compatibility.

Dobot maintains an official TCP/IP Python V3 project specifically for CR and Nova robots. Its documentation states that the interface applies to V3-series controllers running compatible firmware and provides API access for robot control over TCP/IP.

That makes the CR3 relevant for:

• Research environments.
• Custom PC applications.
• Automated test systems.
• MES or database-connected workflows.
• Vision-guided automation.
• External task scheduling.

However, verify the exact controller revision and firmware before assuming that an online API example applies to the robot being purchased.

CR3 and CR3A use different development generations

This is another reason to distinguish the two robots.

Dobot’s newer official V4 Python SDK is aimed at CRA and other V4-generation robots. Its supported-model information lists CRA models and V4-series platforms.

A business standardising a new fleet should therefore consider software-generation compatibility, not only mechanical specifications.

Communication interfaces

The CR3 specification includes:

• TCP/IP.
• Modbus.
• Wi-Fi.
• RS485 at the end effector.
• Digital controller I/O.
• Analogue controller I/O.
• ABZ incremental encoder interface.

These interfaces allow the CR3 to interact with equipment such as:

• PLCs.
• CNC machines.
• Conveyors.
• Grippers.
• Vacuum systems.
• Sensors.
• Inspection systems.
• Production computers.

Do not choose a robot from the API list alone

Before purchase, define the actual integration architecture.

For example:

PLC commands robot → robot controls gripper → machine provides cycle-complete signal → vision system sends part coordinates → robot reports production result to MES.

Then verify that every required interface is supported by the proposed controller, firmware and accessory package.

Dobot CR3 Safety, Collision Detection and SafeSkin

The CR3 belongs to Dobot’s collaborative-robot family, but that does not mean every CR3 application can operate beside people without guarding.

Dobot states that the CR Series includes multiple built-in safety functions and five adjustable collision-detection levels. The company also references ISO 13849 and ISO/TS 15066 in its CR Series safety information.

Collision detection

Adjustable collision sensitivity can allow the robot to respond when unexpected contact occurs.

The correct setting depends on:

• Robot speed.
• Payload.
• Tool geometry.
• Body region that could be contacted.
• Whether trapping is possible.
• Stopping distance.
• Process hazards.

Reducing sensitivity to prevent nuisance stops can increase risk. Increasing sensitivity can reduce productive speed or cause false stops.

Safety tuning should therefore be based on the application risk assessment.

What is Dobot SafeSkin?

SafeSkin is Dobot’s optional non-contact pre-collision sensing technology.

Dobot’s CR documentation describes SafeSkin as detecting unexpected objects approaching the robot from up to approximately 15 cm, allowing the system to react before physical contact.

This can be valuable for applications where workers periodically approach the robot.

But buyers should confirm:

• Whether SafeSkin is actually included in the quotation.
• Which robot sections are covered.
• The effective detection distance in the real installation.
• How different materials are detected.
• What robot response is triggered.
• How SafeSkin is incorporated into the validated safety architecture.

SafeSkin should not be treated as a universal substitute for a risk assessment, guarding or safety-rated external sensing.

Collaborative robot vs collaborative application

This distinction is critical.

A collaborative robot can still become dangerous when equipped with:

• A sharp screwdriver.
• A hot dispensing nozzle.
• A heavy workpiece.
• A cutting tool.
• A pinch-producing gripper.
• A fixture that creates trapping points.

The current ISO 10218-2:2025 standard addresses safety of the complete industrial robot application and integration, while ISO/TS 15066 continues to provide guidance specific to collaborative industrial robot systems.

Minimum safety questions before buying

• Can a person enter the robot workspace during automatic operation?
• Can the robot trap somebody against a machine or fixture?
• What is the maximum credible impact?
• Does the tool introduce cutting, crushing, heat or electrical hazards?
• What safety functions stop the robot?
• What happens after a power or communication failure?
• Who resets the cell?
• What validation is required before production release?

A cobot cell should be approved as a system, not by reading the robot brochure alone.

Best Uses for the Dobot CR3

1. Small-part pick and place

One of the best overall CR3 applications.

The 3 kg payload and compact reach make the robot suitable for moving small components between fixtures, trays, conveyors and inspection equipment.

The strongest applications use lightweight grippers and keep the entire cycle inside a compact workspace.

2. Light assembly

Dobot explicitly positions the CR3 for assembly.

Possible operations include:

• Component placement.
• Simple mechanical assembly.
• Connector insertion.
• Fixture loading.
• Small-subassembly handling.

Force-sensitive or tolerance-critical assembly may require additional tooling or sensing.

3. Dispensing and gluing

The CR3 can carry compact dispensing hardware and follow programmed paths for:

• Adhesive.
• Sealant.
• Grease.
• Potting compounds.
• Other low-mass dispensing processes.

The process equipment, hose forces and dispenser weight must remain within the robot’s usable payload.

4. Quality inspection

A camera, scanner or compact sensor can be moved between defined inspection poses.

This can work well when one sensor needs to view a component from several angles.

The CR3’s repeatability is useful here, although the complete inspection accuracy depends heavily on calibration and sensor performance.

5. Laboratory automation

The CR3 can be attractive for engineering and research laboratories because its 16.5 kg body and compact working envelope are easier to accommodate than a large industrial arm.

Possible applications include:

• Instrument loading.
• Sample handling.
• Automated testing.
• Repeated manipulation experiments.
• Camera positioning.

For laboratory processes involving chemicals, contamination control or regulated workflows, the robot’s materials and IP rating must be reviewed carefully.

6. Education and robotics training

Unlike smaller educational robots, the CR3 introduces students to a full six-axis collaborative-robot workflow involving:

• Industrial motion programming.
• TCP configuration.
• Coordinate systems.
• I/O.
• Machine communication.
• Risk assessment.
• End-effector integration.

This makes it more representative of real automation engineering than a desktop demonstrator.

7. Light machine tending

The CR3 can load and unload small machines when:

• The door and loading point are close to the robot.
• The complete tool and workpiece remain below the payload limit.
• The reach envelope works with the required tool orientation.
• Machine communication can be integrated reliably.

Larger CNC machines will frequently push buyers toward a longer-reach cobot.

8. Retail and beverage automation

Dobot itself highlights beverage and retail scenarios for the CR3.

Its compact footprint can suit counter-based installations where a larger industrial arm would be impractical.

Public-facing use, however, creates additional safety, cleaning, reliability and customer-interaction requirements that should be assessed separately.

When the Dobot CR3 Is Not the Right Robot

The CR3 should not be selected simply because the workpiece appears small.

Reject or reconsider it when the application requires characteristics outside its real operating envelope.

• More than 3 kg at the flange: choose a higher-payload cobot.
• Long machine reach: 620 mm working radius can become restrictive very quickly.
• Large grippers: bulky end effectors can consume payload and reduce practical access.
• Fast industrial production: verify complete cycle time rather than relying on 2 m/s maximum TCP speed.
• Washdown environments: IP54 is not equivalent to a washdown-rated robot.
• Heavy dust or harsh contamination: environmental suitability requires separate evaluation.
• Hazardous tooling: a collaborative arm does not remove process hazards.
• Large multi-machine cells: longer reach may significantly simplify the installation.
• Greenfield 2026 installations: CR3A should normally be quoted before committing to the previous-generation CR3.

3 kg becomes small faster than buyers expect

The most common specification trap is ignoring end-effector mass.

If your proposed tool weighs 1.5 kg, only 1.5 kg remains before the nominal 3 kg payload limit—and the actual application must still account for centre of gravity and dynamic loading.

For many industrial applications, moving from CR3 to a 5 kg or 7 kg model can provide useful engineering margin.

Compare the Dobot CR5A or browse other industrial robots if payload margin is already tight during concept design.

Dobot CR3 Alternatives in 2026

The strongest alternative depends on whether the buyer prioritises price, ecosystem, reach, payload, environmental protection or long-term support.

Current manufacturer documentation gives the UR3e a 3 kg payload and 500 mm reach, FANUC’s CRX-5iA a 5 kg payload and 994 mm reach, and OMRON’s TM5-700 a 6 kg payload and 700 mm reach.

CR3 vs CR3A

Choose CR3A for a new Dobot deployment unless the CR3 offers a clear price, support or installed-base advantage.

CR3 vs Universal Robots UR3e

The CR3 offers more nominal working radius and slightly tighter published repeatability.

The UR3e is lighter and benefits from one of the industry’s largest collaborative-robot software, accessory and integrator ecosystems.

The correct choice often depends more on local support and existing factory standards than on 0.01 mm of published repeatability.

CR3 vs FANUC CRX-5iA

These are not direct mechanical equivalents.

The FANUC provides significantly greater reach and payload and publishes IP67 protection, but the robot is also larger and heavier.

Choose the CR3 when compact size is the priority; choose the FANUC when reach, payload and industrial-duty support justify the larger system.

CR3 vs OMRON TM5-700

The TM5-700 offers 6 kg payload and 700 mm reach and integrates closely with OMRON’s automation ecosystem.

However, OMRON currently states that production of the referenced TM5-700 configuration is planned to end on 31 March 2027, which should be included in any long-term platform decision.

Is the Dobot CR3 Worth It in 2026?

Yes—but only when the application genuinely fits the CR3 and the commercial deal compensates for buying the older Dobot generation.

Mechanically, the CR3 remains competitive for light automation.

A 3 kg payload, ±0.02 mm repeatability, 620 mm working radius and 16.5 kg body do not suddenly become unusable because a newer model exists.

The purchasing question is different:

Does buying the CR3 today provide enough cost, compatibility or availability advantage to justify choosing it instead of CR3A?

Reasons the CR3 can still be good value

• The application is simple and already validated.
• 3 kg provides sufficient payload margin.
• The complete workspace fits comfortably within the CR3 envelope.
• A local distributor has strong CR-Series expertise.
• The organisation already operates CR robots.
• Existing tooling, programs or spare parts can be reused.
• The discounted purchase price is meaningful after integration costs are included.

Reasons to choose CR3A instead

• It is a greenfield automation project.
• The price difference is small.
• The robot is expected to operate for many years.
• Future Dobot software development matters.
• You want the newer controller generation.
• You do not have existing CR-Series standardisation.

A useful ROI test

Do not calculate ROI using robot price alone.

Use:

Total installed project cost ÷ verified annual labour/process saving.

And include:

• Integration engineering.
• Fixtures.
• Tooling.
• Safety.
• Training.
• Maintenance.
• Expected downtime.
• Changeover labour.

A €3,000 cheaper robot that creates €10,000 of additional integration or lifecycle cost is not the cheaper automation system.

Dobot CR3 Buying Checklist

1. Define the task. Record every pickup, process and placement point.
2. Calculate total payload. Include gripper, adapter, sensors, cables and workpiece.
3. Check centre of gravity. Do not validate from mass alone.
4. Model the workspace. Verify poses using the real tool orientation.
5. Set the cycle-time target. Measure the complete application rather than robot maximum speed.
6. Choose the end effector. Confirm electrical, pneumatic and communication requirements.
7. Define machine communication. List every PLC, CNC, conveyor and sensor signal.
8. Confirm controller generation. Record hardware and firmware versions.
9. Confirm software requirements. Verify DobotStudio, API and external-development compatibility.
10. Review environmental conditions. Temperature, liquids, dust and cleaning procedures matter.
11. Complete the risk assessment. Include tool, workpiece, fixtures and surrounding machinery.
12. Confirm SafeSkin scope. If required, state exactly what hardware is supplied.
13. Request a CR3A alternative. Compare the same end effector and integration scope.
14. Confirm lifecycle support. Ask about parts, repairs, firmware and controller availability.
15. Define acceptance tests. Require the final cell to meet measurable criteria before sign-off.

Pro tip: send suppliers the application specification rather than asking, “How much is a CR3?” The useful quotation is the cost of solving the process—not the cost of putting a robot arm in a box.

How to Buy the Dobot CR3

Dobot sells through its regional network and authorised automation partners. Availability of the original CR3 varies by region, and buyers should confirm whether a quoted unit is current stock, distributor inventory or a special-order configuration.

A good enquiry should include:

• Country and installation location.
• Industry.
• Application.
• Workpiece weight.
• Required tool.
• Required reach.
• Required cycle time.
• Machine or PLC interface.
• Vision requirements.
• Human access to the cell.
• Environmental conditions.
• Expected production hours.
• Required installation date.

Before paying, request:

• Exact CR3 model and controller revision.

What Is the Status of the Dobot CR3 in 2026?

This is where older CR3 reviews can mislead buyers.

The CR3 is still documented

Dobot’s current website continues to host the original CR3 product page, specification table and CR-Series documentation.

So it would be incorrect to describe the CR3 as an undocumented historical product.

But CR3A is the newer generation

Dobot launched the CRA Series in September 2023 and described it as a fully enhanced new generation covering payloads from 3 kg to 20 kg.

CR3A occupies the 3 kg position in that family.

Regional availability is already changing

At least some regional Dobot partners now identify the original CR family as end-of-sale and point new buyers toward CRA models. That should not be interpreted as proof of one worldwide discontinuation date, but it is strong reason to confirm local lifecycle status before purchase.

Software development has also moved forward

Dobot’s current V4 development repository focuses on CRA and other newer-generation robots, while the original CR family is supported through the older V3-generation TCP/IP development stack.

For a new fleet, that matters more than it might appear.

Software, controller hardware, firmware, training material and replacement-part availability can influence ownership cost long after the original robot purchase.

2026 buyer conclusion: treat the CR3 as a capable previous-generation cobot, not as Dobot’s current default 3 kg platform.

Is the CR3 good for machine tending?

It can be, when the machine is compact and the complete tool plus workpiece remain within the 3 kg payload and reach envelope.

Is the CR3 good for education?

Yes. It gives students access to six-axis industrial robot programming, I/O, coordinate systems, external communication and safety concepts.

Can the CR3 be used for welding?

The 3 kg payload, compact reach and environmental specification make other cobots generally more suitable for typical production welding applications.

What is the difference between CR3 and CR3A?

CR3A is the newer-generation Dobot model. It preserves the basic 3 kg payload, 620 mm working radius and ±0.02 mm repeatability while moving to the newer CRA hardware and software generation and publishing higher speeds for several joints.

Should I buy CR3 or CR3A?

For a completely new 2026 deployment, request CR3A first. Choose the original CR3 when it offers a meaningful commercial or installed-base advantage and the supplier can support it for the required lifecycle.

What is the best alternative to the Dobot CR3?

CR3A is the closest direct replacement. Universal Robots UR3e is strong for ecosystem maturity, FANUC CRX-5iA offers considerably more reach and payload, and OMRON TM5-700 offers higher payload with an integrated automation ecosystem.

Is the Dobot CR3 worth buying in 2026?

Yes, for the right compact light-duty application and commercial terms. It is less compelling when the original CR3 and newer CR3A are similarly priced.

Final Verdict: Should You Buy the Dobot CR3?

The Dobot CR3 remains a capable compact cobot for light-duty automation, especially when the application requires only 3 kg payload and a relatively small working envelope.

Its core specification remains competitive: 16.5 kg body weight, 620 mm working radius, 795 mm maximum reach, ±0.02 mm repeatability and 2 m/s maximum TCP speed.

It is also more than a basic entry-level arm. Dobot provides graphical programming, drag teaching, industrial I/O and external communication options that allow the CR3 to operate as part of a real automation system.

The problem is timing.

In 2026, the CR3 is no longer the obvious Dobot choice simply because you need a compact 3 kg cobot. The CR3A now occupies that position in Dobot’s newer CRA family.

That changes the buying decision from:

Is the CR3 a good robot?

to:

Is there a good enough reason to buy the CR3 instead of the CR3A?

If the answer is existing CR infrastructure, proven programs, spare parts, immediate stock or a substantial commercial discount, the original CR3 can still be a sensible purchase.

If the installation is completely new and expected to operate for years, CR3A should normally be quoted first.

In either case, do not buy from payload and reach alone.

Define the complete tool, map every required pose, calculate payload and centre of gravity, establish the safety concept, specify machine communication and run the proposed configuration against measurable acceptance criteria.

That process will tell you far more about whether the CR3 is right for your factory than the brochure ever can.
