RH6D Child-size Dexterous Robot Hand

About

About RH6D Child-size Dexterous Robot Hand

RH6D is a compact five-finger hand sized for child-scale humanoids and medium robot arms. Its 15 degrees of freedom reproduce finger flexion and thumb opposition within a smaller palm and wrist envelope. Mechanically linked joints allow the fingers to conform around objects while keeping actuator count and hand mass manageable.

Seed Robotics supplies left- and right-hand versions with communications and control support for research integration. The hand is used for grasping, teleoperation, social robotics and manipulation experiments where an adult-size end effector would distort the host robot’s proportions or payload budget.

Research

  • Seed Robotics ROS control and pressure-sensor stack for RH-series hands

    2022-08-22 - Research Publication - Seed Robotics publishes this ROS Noetic package for its RH-series hands and manipulators, explicitly including RH4D, RH6D and RH8D. The control package exposes joint position, speed and stiffness commands through ROS messages, with Python and C++ examples and a documented maximum working frequency of 50 Hz. A companion sensor package reads FTS1 and FTS3 pressure sensors, and RH6D and RH8D examples demonstrate pressure-threshold and constant-force grasp control.
