UMI, but for humanoid hands.
UMI-style capture already works great for simple grippers. For a high-DOF hand, where the action space is huge and contact force carries the important signal, matching the data collector to the hand matters even more.
Chestnut just announced that pair:
Aero Hand, an 18-DOF human-sized dexterous hand (tendon/linkage hybrid, tested for 3M+ cycles), and
Aero UMI, a wearable exoskeleton whose kinematics exactly matches the robotic hand, with direct per-joint angle sensing accurate to 0.1°.
Zero embodiment gap for human data collection. Doubles as a teleop rig.
