Unbox performance unleashed with the DOBOT CR20A — a high-payload collaborative robot arm breaking through the 20 kg limit with a 1,700 mm working radius. Built for heavy-duty picking, packing, palletizing, and welding across automotive, home appliance, and metal processing industries.
Unbox performance unleashed with the DOBOT CR20A — building upon the safety, efficiency, flexibility, and ease of use of the CR series, the CR20A breaks through the payload limit to 20 kg, opening up a wider range of applications for collaborative robot arms. With a 1,700 mm working radius, the CR20A meets the demands of heavy duty picking, packing, palletizing, and welding across the automotive, home appliances, logistics, and metal processing industries.
Key Features:
- High Payload, Wide Reach – A maximum payload of 20 kg combined with a 1,700 mm working radius unlocks a broader range of heavy-duty applications for this collaborative robot arm.
- Advanced Motion Control – An advanced motion control algorithm allows the CR20A to operate more stably, reducing residual vibrations by 50% during high-speed emergency stops.
- User-Friendly, Fast Deployment Design – Features an industry first dual channel end effector design that connects directly to multiple end tools, plus a visual status indicator at the base for intuitive recognition of operating status.
- 24 Interface Ports for Maximum Flexibility – Supports Profinet and Ethernet/IP communication protocols and connects seamlessly with PLC systems, with 24 digital IO ports offering industry leading support for both PNP and NPN switching.
- High Protection Level for Safer Collaboration – Both the robot body and control box achieve an IP54 protection rating. The robot automatically sounds an alarm when overloaded, while an innovative electromagnetic brake protection system reduces end tool drop distance during power failure.
- High-Speed TCP Motion – Delivers a maximum TCP speed of 2,000 mm/s, ensuring fast cycle times for demanding production environments.
