About

About RH8D

RH8D uses eight onboard actuators to control 19 articulated degrees of freedom across the fingers, thumb and spherical wrist. Three-segment fingers and a fully opposable thumb support power, precision and lateral grasp patterns within a hand weighing approximately 620 grams.

The hand can hold roughly 750 grams to one kilogram in three-dimensional grasps and withstand higher vertical pulling loads. Optional tactile fingertip sensing and a palm time-of-flight sensor add contact and proximity information for teleoperation, humanoid manipulation and robot-learning experiments.

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.
