The DOBOT CRA series is DOBOT's new generation of six-axis collaborative robots, covering 3 kg to 20 kg payloads and 620 mm to 1700 mm reach. Every model shares the same controller, software and safety system, so it is easy to pick the right size for machine tending, welding, palletising, assembly or pick-and-place. With a proper risk assessment, CRA cobots can work safely alongside people without fencing. The CR3A, CR5A and CR10A are also available with DOBOT SafeSkin (CR3AS, CR5AS, CR10AS).
