LEAP Hand / Carnegie Mellon LEAP Hand v2 Advanced
Understand this hand
LEAP Hand v2 Advanced combines a hybrid rigid–soft structure with an articulated palm. The project describes 17 powered motors and 21 total DOF.
- What distinguishes it
- Two powered palm articulations are part of this architecture. The Standard and Advanced names do not indicate interchangeable hardware.
- Before you build
- Verify available assembly assets and API revision, then document tendon coupling and the palm coordinates in your controller or retargeting map.
