Cost-effective research-grade four-finger hand from Wonik Robotics with 16 independently torque-controlled joints (4 DoF per finger) and 1.08 kg total weight (0.17 kg fingers, 0.19 kg thumb) at 5 kg payload. DC-motor drive with 1:369 gear ratio, 0.70 N·m max joint torque and 0.11 s/60° max speed; potentiometer joint resolution of 0.002°, CAN communication at 333 Hz and 24 VDC/100 W power, widely used for grasp and manipulation research.
COMPONENT
The Allegro Hand V4 from Wonik Robotics (Korea) is a four-finger dexterous hand for grasp and manipulation research and education: 3 fingers plus an opposable thumb with 16 independent torque-controlled joints (4 per digit), driven by DC motors with torque/current control and a 1:369 reduction ratio, delivering 0.70 N·m max joint torque and 0.11 s/60° joint speed. It weighs just 1.08 kg total (0.17 kg per finger, 0.19 kg thumb), features 0.002° potentiometer resolution, 333 Hz CAN communication, 5 kg payload capacity, and runs on 24 V / 100 W. With full APIs and tutorials for Windows / Linux / ROS / ROS 2 and 180+ research partners publishing with the platform, it is one of the most widely used research dexterous hands.
