UCLA's TriMI: a $800 tri-modal robot hand for demos, haptic teleop, and policy execution
DennisHongRobot · x · 2026-11-11
UCLA (with UC Berkeley) released TriMI, a tri-modal manipulation interface combining direct demonstration capture, joint-level haptic teleoperation, and robotic policy execution on the same hardware, accepted to the CoRL 2026 UMI Arena Workshop.
- Four-finger design with 13 DoF; bill of materials USD 800 (excluding tracking device and wrist camera)
- A diffusion policy trained on collected demos scored 90% (18/20) on cube pick-and-place and 75% (12/16) on cap unscrewing
- Full open-source release coming soon
