What makes it work
DOBOT CR20A
Performance unleashed — 20 kg payload and 1,700 mm working radius make the CR20A the ultimate collaborative robot for high-volume, heavy-duty industrial production.
Performance Unleashed With High Payload and Wide Radius
Building upon the proven safety, efficiency, flexibility, and ease of use of the CRA series, the DOBOT CR20A pushes the payload ceiling to 20 kg — the most powerful collaborative robot in the CRA lineup. With an expansive working radius of 1,700 mm and a maximum linear speed of 2 m/s, the CR20A is built to meet the demands of the most intensive heavy-duty picking, packing, palletizing, and welding operations across the automotive, home appliance, logistics, and metalworking industries. An industry-first dual-channel end effector design simplifies tool connections, while an advanced motion control algorithm reduces residual vibration by 50% during high-speed emergency stops — ensuring stability even under maximum load. The CR20A supports Profinet and Ethernet/IP communication protocols, connects seamlessly with PLC systems, and features an expanded I/O configuration with 2 analog inputs, 4 digital outputs, and 4 digital inputs — multiplexed with RS485. With IP54 protection on both the robot body and the control box, and innovative electromagnetic brake technology, the CR20A delivers the most capable safe collaboration in the CRA series.
Built Around Four Principles
Engineered for the Modern Factory Floor
User-Friendly Design for Faster Deployment
The CR20A adopts an industry-first dual-channel end effector design, allowing direct connection to multiple end tools without complex adapters or custom wiring. A visual status indicator at the base provides immediate, intuitive recognition of the robot's operating state — reducing setup time and minimising operator errors from first deployment. With a working radius of 1,700 mm and a maximum payload of 20 kg, the CR20A covers the largest workcell footprints in the CRA series, handling components that no other model in the lineup can reach.
Advanced Motion Control for Stable, High-Speed Operation
Powered by an advanced motion control algorithm, the CR20A operates with exceptional stability across its wide working envelope — even at maximum 20 kg payload. Residual vibrations during high-speed emergency stops are reduced by 50%, protecting the heaviest workpieces and surrounding equipment. A maximum linear speed of 2 m/s ensures competitive cycle times, while the 500 W motor power delivers the torque needed to move large, heavy components with smooth, consistent motion throughout production shifts.
Expanded IO and Industrial-Grade Communication
The CR20A features an expanded I/O configuration — 2 analog inputs, 4 digital outputs, and 4 digital inputs multiplexed with RS485 — offering more peripheral integration points than the smaller models in the CRA series. Profinet and Ethernet/IP protocol support allows direct connection to existing PLC infrastructure without custom middleware. This combination makes the CR20A the natural choice for complex production line integration where more signals, more tools, and more coordination are required.
High Protection Level for Safer Collaboration
Both the robot body and the control box achieve IP54 protection, guarding against dust and liquid ingress in typical manufacturing environments. When overloaded, the robot automatically triggers an alarm to prevent mechanical damage. The innovative electromagnetic brake protection reduces end-tool drop distance in the event of a power failure — a critical safety feature when handling 20 kg payloads near personnel or precision workpieces. These protections make the CR20A a dependable partner wherever maximum-payload human-robot collaboration is required.

Common Questions About the CR20A
What is the maximum payload and working radius of the DOBOT CR20A?
The DOBOT CR20A supports a maximum payload of 20 kg and has a working radius of 1,700 mm — the highest payload and widest reach in the entire CRA series. This makes it the preferred choice for the most demanding heavy-duty picking, palletizing, loading, and welding tasks across large industrial workcells.
How does the CR20A differ from the CR16A?
The CR20A offers a significantly higher payload of 20 kg versus 16 kg for the CR16A, and a much wider working radius of 1,700 mm versus 1,000 mm. The CR20A also weighs 70 kg versus 40 kg, draws 500 W versus 350 W, has a 6 m cable to controller versus 5 m, and features expanded I/O with 4×DO and 4×DI versus 2×DO and 2×DI. Its repeatability is ±0.05 mm compared to ±0.03 mm on the CR16A.
What I/O configuration does the CR20A have?
The CR20A features 2 analog inputs, 4 digital outputs, and 4 digital inputs — all multiplexed with RS485. This is an expanded configuration compared to smaller CRA models, giving the CR20A more peripheral integration points for complex multi-device production line architectures. It also supports Profinet and Ethernet/IP communication protocols for seamless PLC integration.
Can the CR20A be mounted in different orientations?
Yes. The DOBOT CR20A supports installation at any angle — including floor, ceiling, wall, and inclined positions — without requiring additional mounting hardware or configuration changes. This allows flexible integration into large-format workcell designs, overhead gantry configurations, and multi-robot production lines.
What safety features are built into the CR20A?
The CR20A includes an automatic overload alarm that triggers when excessive load is detected, an electromagnetic brake protection system that limits end-tool drop distance at power failure, and an advanced motion control algorithm that reduces residual vibration by 50% during high-speed emergency stops — making it a safe and dependable choice for human-robot collaborative environments handling the highest payloads in the CRA range.
