Description
The ORCA v1 hand aims to give robots a human-like grasp and feel. It closely mirrors the shape and joint layout of a human hand, including an opposable thumb and articulated fingers — which lets it hold and manipulate everyday objects naturally. Because of its realistic proportions and joint configuration, it works well for teleoperation, imitation learning, or any project that builds on human-hand movements.

What makes ORCA v1 especially appealing is its accessibility. The creators built it to be affordable and easy to reproduce: many of its structural parts come from 3D-printed soft-skin designs and standard off-the-shelf motors. As a result, it became much simpler for labs, students, or hobbyists to build and experiment with a high-quality robotic hand.
