ROH-A002

About this product

ROH-A002 is OYMotion's anthropomorphic robotic end effector with five independently moving fingers, six active degrees of freedom and 11 moving joints. Integrated motor drivers and PID control support programmable pinching, grasping and gestures. The official page lists a 580 ±5 g mass, ±1 mm repeatability and UART, RS485 and CAN interfaces, alongside SDK, ROS, ROS2 and URDF support. Intended uses include humanoids, inspection robots and research equipment. The manufacturer's static finger-load and bent-finger lifting figures describe specific test conditions rather than unrestricted active gripping capability.
