The DOBOT CR20A is a high-payload collaborative robot with a 20 kg maximum payload and 1,700 mm working radius. It achieves ±0.05 mm repeatability with advanced motion control that reduces residual vibrations by 50 percent during high-speed emergency stops. An industry-first dual-channel end effector design allows direct connection to multiple end tools, and a visual status indicator at the base provides intuitive operating state recognition. It features 24 digital I/O ports supporting PNP and NPN switching, Profinet and Ethernet/IP communication with PLC, and IP54 protection on both body and control box. An electromagnetic brake reduces end tool drop distance on power failure. It targets welding, palletizing, loading and unloading, assembly, bin picking, gluing, polishing, and quality inspection in automotive, home appliances, logistics, and metal processing industries.
