What makes it work
DOBOT CR3A
A high-performance 6-axis collaborative robot engineered for precision, safety, and flexible industrial deployment.
Safe, Flexible and Self-Learning Collaborative Robot
Building upon the proven safety, efficiency, flexibility, and ease of use of the CRA series, the DOBOT CR3A breaks through the payload ceiling to 3 kg, opening a wider range of applications for collaborative robots in real-world industrial environments. With a working radius of 620 mm and a maximum linear speed of 2 m/s, the CR3A is built to meet the demands of heavy-duty picking, packing, palletizing, and welding 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. The CR3A supports Profinet and Ethernet/IP protocols and provides 24 digital IO ports with PNP and NPN switching. With IP54 protection on both robot body and control box, and innovative electromagnetic brake technology, the CR3A delivers safe, reliable collaboration in demanding production settings.
Built Around Four Principles
Engineered for the Modern Factory Floor
User-Friendly Design for Faster Deployment
The CR3A introduces an industry-first dual-channel end effector design, allowing direct connection to multiple end tools without complex adapters or wiring. A visual status indicator at the base provides immediate recognition of the robot's operating state — reducing setup time and operator errors. With a working radius of 620 mm and a payload of 3 kg, the CR3A fits naturally into compact workcells while handling typical material weights in light industrial production.
Advanced Motion Control for Stable, High-Speed Operation
Powered by an advanced motion control algorithm, the CR3A operates with exceptional smoothness. Residual vibrations during high-speed emergency stops are reduced by 50%, protecting both workpieces and surrounding equipment. A maximum linear speed of 2 m/s keeps cycle times competitive while the ±0.02 mm repeatability ensures part-level precision on every pass — pushing throughput without sacrificing quality.
24 IO Ports and Industrial-Grade Communication
The CR3A ships with 24 digital IO ports and support for both PNP and NPN switching, enabling wide-ranging peripheral integration. Profinet and Ethernet/IP protocol support allows direct connection to existing PLC infrastructure. Two analog inputs, two digital outputs, and two digital inputs at the end effector are multiplexed with RS485 for tool-level communication — covering virtually any automation architecture.
High Protection Level for Safer Collaboration
Both the robot body and 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 further reduces end-tool drop distance in the event of a power failure — a critical safety feature when operating near personnel or delicate workpieces.

Common Questions About the CR3A
What is the maximum payload and working radius of the DOBOT CR3A?
The DOBOT CR3A supports a maximum payload of 3 kg and has a working radius of 620 mm. This combination makes it well-suited for light to medium-duty pick-and-place, assembly, palletizing, and welding tasks in space-constrained production environments.
What protection rating does the CR3A carry?
Both the robot body and the control box are rated IP54, meaning they are protected against dust ingress and low-pressure water splashes from any direction. This makes the CR3A suitable for typical industrial manufacturing environments where exposure to dust and light moisture is common.
Which communication protocols does the CR3A support?
The CR3A supports Profinet and Ethernet/IP communication protocols, allowing it to connect directly to most industrial PLCs and automation controllers without additional middleware. It also provides 24 digital IO ports with support for both PNP and NPN switching for broad peripheral compatibility.
Can the CR3A be mounted in different orientations?
Yes. The DOBOT CR3A supports installation at any angle — including floor, ceiling, wall, and inclined positions — without requiring additional mounting hardware or configuration changes. This allows it to be integrated into a wide variety of workcell designs.
What safety features are built into the CR3A?
The CR3A includes an automatic overload alarm, an electromagnetic brake protection system that limits end-tool drop at power failure, and an advanced motion control algorithm that reduces residual vibration by 50% during high-speed emergency stops — making it a robust choice for human-robot collaborative environments.
