Dobot CRA Collaborative Robot (CR20A)

An industrial arm is rarely judged by the smooth cycle it repeats all shift. It is judged by the half-second nobody planned for: a power cut with a loaded gripper, or an emergency stop at full speed. The Dobot CRA Collaborative Robot (CR20A) is engineered for those moments as carefully as for the routine ones. It is the high-payload model of DOBOT's CRA Series, carrying up to 20 kg across a 1,700 mm working radius. An electromagnetic brake limits how far the end tool drops when power is lost, and a motion control algorithm halves residual vibration during high-speed emergency stops. Strength and composure are designed in together, which is what heavy collaborative work demands.

Robots Middle East sells the CR20A and supplies it to manufacturers, logistics operators and system integrators throughout the Middle East. Our team prepares each quotation around the application you describe. Robots Middle East also coordinates delivery, customs clearance and after-sales support across the region, so the arm reaches your facility ready for integration and backed by a local point of contact.

Background

DOBOT and the CRA family

DOBOT is a robotics manufacturer whose portfolio extends from collaborative arms to humanoid and legged robots; the full range we carry is gathered in our Dobot category. The CRA Series is the company's line of collaborative arms, and the manufacturer names several branches within it: the standard CRA Series, the CRAF Series with a torque sensor, and the CRA-IP68 Series. Within that family, the CR20A is designated the High Payload Model. It is the member intended for the heavier loads and longer reaches found in automotive, home appliance, logistics and metal processing plants, where much handling is still done by hand.

Dual-channel tooling and stable motion

Two design decisions set the CR20A apart from a conventional arm. The first is at the wrist. DOBOT describes the dual-channel end effector design as an industry first, and it allows the arm to connect directly to multiple end tools. For integrators, this means fewer adaptors and less custom wiring between the flange and the gripper, welding torch or vacuum head. A visual status indicator at the base shows operators the robot's state at a glance.

The second decision is in the control. An advanced motion control algorithm keeps the arm steadier in operation and reduces residual vibrations by 50% during high-speed emergency stops. Connectivity is broad: the robot supports Profinet and Ethernet/IP, and it offers 24 digital IO ports that switch between PNP and NPN. That lets the CR20A fit existing PLC environments rather than forcing the line to adapt to the robot.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the power consumption, the controller's dimensions or weight, the number of axes, the joint torque, the safety certifications or the contents of the box; Robots Middle East confirms each of these with your quotation.

How does the CR20A behave when power fails or an emergency stop is triggered?

With a 20 kg payload, the critical question is what the arm does when something goes wrong. The CR20A addresses two such situations. On power failure, its electromagnetic brake protection reduces the distance the end tool drops. This matters when the gripper is holding a heavy carton, a sheet of metal or a welding torch above a fixture. When an emergency stop is triggered at high speed, the motion control algorithm cuts residual vibration by 50%, so the arm settles more quickly and the load is shaken less. The arm also sounds an alarm when it is overloaded, which warns operators before an unsuitable load becomes a damaged tool or a dropped part.

Together, these features make the CR20A suited to applications where loads are heavy enough for an uncontrolled stop to carry real consequences. We recommend that your risk assessment and cell design are reviewed with our team. The safety certifications are not stated in our sources and are confirmed at quotation.

Which CRA version should I choose: CR20A, CRAF or CRA-IP68?

The CR20A is the right starting point when load and reach are the deciding factors: it is the High Payload Model, with 20 kg at a 1,700 mm radius and a TCP speed of up to 2,000 mm/s. Two other branches of the family address different priorities. Where a task depends on sensing contact force, such as fitting, polishing or careful placement, the CRAF Series is the version the manufacturer equips with a torque sensor. Where the cell is exposed to water, washdown or heavy dust, consider the CRA-IP68 Series, since the CR20A carries an IP54 rating. Our sources do not give figures for those versions, so we do not transfer any CR20A value to them. Robots Middle East will set out the matching specifications when you request a comparison.

Who is the Dobot CRA Collaborative Robot (CR20A) for?

The CR20A is aimed first at the four industries the manufacturer names. Automotive suppliers can use it to move heavy components and run welding cells. Home appliance makers need a strong arm for bulky parts and finished goods. Logistics operators want to automate picking, packing and palletising at the end of the line. Metal processing plants handle dense parts that tire workers quickly. System integrators form a further group: the Profinet and Ethernet/IP support, PNP/NPN switching and dual-channel tooling help them deploy the arm within existing control architectures.

The CR20A installs upright, has a 6 m cable to its controller and operates between 0° and 50° C. Buyers should therefore check their floor layout and ambient conditions early, which matters particularly in warehouses in hot climates. Lighter tasks may be better served by a smaller collaborative arm, and our Cobots category shows the alternatives. For force-sensitive work, the CRAF Series is the better fit. For wet or very dusty environments, ask about the CRA-IP68 Series.

What is the Dobot CRA Collaborative Robot (CR20A) used for?

1. Heavy-duty picking — lifting dense parts and cartons from conveyors, bins or racks without manual strain.
2. Packing — placing products into cases and boxes at a steady rhythm through the shift.
3. Palletising — building stable pallet loads at the end of the line using the long working radius.
4. Welding — guiding a torch with ±0.05 mm repeatability in automotive and metalwork cells.
5. Automotive component handling — moving heavier assemblies between stations and fixtures.
6. Metal processing and home appliances — loading and transferring bulky or heavy workpieces on production lines.

Pricing and Availability

The price of the CR20A depends on the configuration, tooling and integration scope of your project, so Robots Middle East quotes each order individually. Delivery, customs and support are arranged with the quotation. Our team can also advise on the specifications not yet published and confirm every figure against the current datasheet.

Frequently Asked Questions

What is the maximum payload of the CR20A?

The CR20A has a maximum payload of 20 kg, which makes it the High Payload Model of the CRA Series.

How far can the CR20A reach?

Its working radius is 1,700 mm, enough for palletising and for reaching across wide conveyors and fixtures.

Which industrial protocols does it support?

It supports Profinet and Ethernet/IP and offers 24 digital IO ports with PNP and NPN switching.

Can the CR20A be mounted on a wall or ceiling?

The published installation orientation is upright. Please discuss any other mounting arrangement with our team before ordering.

Is the CR20A suitable for dusty or wet areas?

The CR20A is rated IP54. For environments that require stronger sealing, Robots Middle East can advise on the CRA-IP68 Series.

What happens if the power fails while the arm is carrying a load?

The electromagnetic brake protection reduces the drop distance of the end tool at power failure, and an alarm sounds if the arm is overloaded.

Where can I buy the Dobot CRA Collaborative Robot (CR20A) and what does it cost?

You can buy the CR20A from Robots Middle East, which supplies it across the Middle East. The cost depends on your configuration and project scope, so please request a tailored quotation through this page.

Summary

Heavy collaborative work is defined as much by the unplanned moment as by the routine cycle, and the CR20A is built for both. In normal operation it carries 20 kg across 1,700 mm with ±0.05 mm repeatability. Its dual-channel tooling and broad connectivity simplify integration. When a stop or power loss interrupts the cycle, its brake protection and vibration control keep the load under control.
