WUJI Hand 2 spins a pen using a policy trained in simulation

A post says WUJI trained its 20-joint Hand 2 to spin a pen in simulation, then ran the trained policy on the physical hand around IROS 2026. A camera tracked markers on the pen and wrist while the policy sent joint targets 50 times a second. The post also describes a sensor glove for live control and says WUJI released code, motion clips, trained models and printable pen files under Apache 2.0.
