What makes it work
DOBOT CR7A
An allround multitasking collaborative robot — combining a 7 kg payload with precise motion control, industrial-grade safety, and versatile deployment across manufacturing environments.
Safe, Flexible and Self-Learning Collaborative Robot
Building upon the proven safety, efficiency, flexibility, and ease of use of the CRA series, the DOBOT CR7A breaks through the payload limit to 7 kg, opening a wider range of applications for collaborative robots in demanding industrial environments. With a working radius of 800 mm and a maximum linear speed of 2 m/s, the CR7A is engineered 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 directly at the wrist, while an advanced motion control algorithm reduces residual vibration by 50% during high-speed emergency stops — ensuring both speed and stability. The CR7A supports Profinet and Ethernet/IP communication protocols, connects seamlessly with PLC systems, and provides 24 digital IO ports with PNP and NPN switching. With IP54 protection on both the robot body and the control box, along with innovative electromagnetic brake technology, the CR7A delivers reliable, safe human-robot collaboration in the most demanding production settings.
Built Around Four Principles
Engineered for the Modern Factory Floor
User-Friendly Design for Faster Deployment
The CR7A 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 the first deployment. With a working radius of 800 mm and a maximum payload of 7 kg, the CR7A handles a broad range of part weights across medium-scale industrial workcells.
Advanced Motion Control for Stable, High-Speed Operation
Powered by an advanced motion control algorithm, the CR7A operates with exceptional smoothness across its full working envelope. Residual vibrations during high-speed emergency stops are reduced by 50%, protecting both workpieces and surrounding equipment without sacrificing cycle time. A maximum linear speed of 2 m/s combined with ±0.02 mm repeatability means the CR7A pushes throughput while maintaining the part-level precision that demanding applications require.
24 IO Ports and Industrial-Grade Communication
The CR7A ships with 24 digital IO ports and industry-leading support for both PNP and NPN switching, enabling wide-ranging peripheral integration from grippers to sensors. Profinet and Ethernet/IP protocol support allows the robot to connect directly to existing PLC infrastructure without custom middleware. Two analog inputs, two digital outputs, and two digital inputs at the end effector are multiplexed with RS485 — covering virtually any automation architecture from standalone workcells to full production line integration.
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 working near personnel or handling delicate workpieces. These protections make the CR7A a trusted partner wherever human-robot collaboration is required.

Common Questions About the CR7A
What is the maximum payload and working radius of the DOBOT CR7A?
The DOBOT CR7A supports a maximum payload of 7 kg and has a working radius of 800 mm. This positions it as an allround multitasker suited for pick-and-place, assembly, palletizing, welding, and loading tasks that exceed the capacity of lighter cobots.
How does the CR7A compare to the CR5A in the CRA series?
The CR7A offers a higher maximum payload of 7 kg versus 5 kg on the CR5A, while its working radius of 800 mm is slightly smaller than the CR5A's 900 mm. The CR7A weighs 24.5 kg compared to 25 kg for the CR5A. Both models share the same ±0.02 mm repeatability, IP54 protection rating, 150 W power draw, and communication protocols.
Which communication protocols does the CR7A support?
The CR7A supports Profinet and Ethernet/IP communication protocols, enabling direct connection 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 CR7A be mounted in different orientations?
Yes. The DOBOT CR7A supports installation at any angle — including floor, ceiling, wall, and inclined positions — without requiring additional mounting hardware or configuration changes. This allows it to integrate into a wide variety of workcell designs and overhead gantry configurations.
What safety features are built into the CR7A?
The CR7A 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 robust and safe choice for human-robot collaborative environments.
