DOBOT CRAF Series – Collaborative Robots with Integrated Force Control

The DOBOT CRAF series is a collaborative 6-axis robot platform with a force/torque sensor integrated directly into the flange. It was developed for applications where defined forces are as critical as position, such as grinding, polishing, assembly, and force-guided processes.

The factory-integrated and calibrated force-sensing technology eliminates the need for additional integration. The cobot is ready for force-controlled applications right away and enables precise, adaptive interaction with workpieces and its surroundings.

Highlights

• Integrated 6-axis force/torque sensor in the flange
• Force-controlled processes without additional integration
• High sensitivity for precise interaction (microforces < 2 N)
• Plug-and-play operation without calibration
• Compatible with grippers and vision systems (I/O remains available)

Benefits / applications

The CRAF series is suitable for applications requiring constant process force or adaptive motion. These include polishing, grinding, force-guided assembly, sensitive handling, and welding applications involving varying parts.

• Polishing and grinding with constant force
• Force-guided assembly processes
• Welding with varying part geometries
• Precision handling of sensitive components
• Research and development in human-robot collaboration
