About

About RUKA-v2

RUKA-v2 is an open-source tendon-driven hand with 16 finger and thumb degrees of freedom and a two-axis parallel wrist. Finger abduction and adduction change the spacing between digits, while the wrist provides independent flexion, extension and radial or ulnar movement.

Actuators sit in the forearm to reduce distal mass, and major structures are 3D printed from published designs. The project includes CAD, assembly instructions, controller software and simulation assets. Researchers demonstrated single- and dual-arm teleoperation across writing, grasping, wiping and object-manipulation tasks.

Capabilities

Source-backed capabilities

  • Capability areas: Robotic grasping, Dexterous manipulation
  • Workflows: End-effector manipulation
  • Operating environments: Robot-learning labs, teleoperation research and humanoid manipulation research
  • Target markets: Researchers who care about reproducible hand design and human-demonstration transfer.
  • Deployment model: Research project hand for open robotics manipulation experiments rather than a mass-market commercial product.
  • Dexterous manipulation

    Research demonstration - 2026-03-27 - NYU researchers report RUKA-v2 across 13 single-arm and bimanual teleoperation tasks and three autonomous manipulation policies, with measured completion-time and success-rate gains over RUKA.
