Robot Hands: Precision Assembly & Industry
Mounted on cobots to grip, assemble, and hand off parts. Electric two-finger grippers are already in everyday use; multi-finger hands start with PoCs for irregular parts and tool handling.
Core functions
- Gripping and assembly with controlled position, speed, and force
- Self-locking on power loss to prevent drops
- Irregular-part grasping and tool use with multi-finger hands (PoC)
Customer value
- Grip force matched to each part prevents scratches, deformation, and drops
- Changeovers by parameter change, with fewer jig swaps
- Test automation of steps that only human hands could do
Check before deploying
- Part shape, weight, and material, plus required stroke and grip force
- Compatibility with the cobot's interface (Modbus, I/O, etc.)
