WUJI HAND 2

About

About WUJI HAND 2

WUJI HAND 2 is a dexterous robotic hand built around a biomimetic skeleton and a soft outer body. Four active joints per finger provide thumb opposition and lateral finger movement. Back-drivable rotary actuation, hybrid force-position control and multi-axis fingertip sensing let developers work with contact forces as well as finger poses. Modular construction supports replacement of individual assemblies.

The hand connects to robot hosts over Ethernet. Wuji’s Python and C interfaces, ROS 2 support, simulation models and glove retargeting tools cover device control, teleoperation and manipulation-policy development. The Wuji-MJLab package runs learned cube-reorientation and reference-tracking pen-spinning policies on physical Hand 2 hardware. External experiments also use the hand on dual-arm research systems and mobile manipulators.
