WUJI Hand 2
WUJI Hand 2 is a second-generation biomimetic five-finger dexterous hand developed by the Chinese company Wuji Technology. It provides 20 active degrees of freedom (4 per finger) and a fully direct-drive design with back-drivable joints, FOC vector control and MIT-style force-position hybrid control running at 1000 Hz across 20 axes.
The hand targets manipulation research, humanoid robot integration and teleoperation. It communicates over Ethernet (RJ45, 100BASE-TX) and runs on 11–13 V DC. According to the official documentation the current unit is a beta prototype without tactile sensors (non-tactile); an IMU module is built in. A pair of these hands ("Dual Wuji") is used in Agile Robots' Agile ONE SN humanoid robot.
