OYMotion ROHand ROH-AP001 Dexterous Hand
OYMotion ROHand (ROH-AP001) is a 640 g dexterous robot hand, 183 mm from middle fingertip to wrist with an 82 mm palm and Ø49 mm wrist. Fingers close in 0.7 s, press ≥1.0 kgf at the thumb tip, hold 30 kg passively on four bent fingers, report finger force, and talk UART, RS485 (SerialCtrl / Modbus-RTU) or CAN at 1 Mbps; −10 to 40 °C.

Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
