Seed Robotics RH4D
The Seed Robotics RH4D is an advanced research manipulator in a compact form factor, sharing the same technology as the human-inspired RH8D, RH7D and RH5D robot hands. It delivers 11 degrees of freedom controlled by 4 smart actuators fully contained inside the unit.
Degrees of freedom
The four actuated axes are wrist rotation, wrist flexion, index flexion, and combined index + middle finger flexion with tendon tension equalization (fingers conform independently to object shape).
Sensing and control
An EROS control board and smart actuators deliver up to 120 Hz feedback for position, speed, temperature, PWM output and high-resolution current measurement on every actuated joint. A palm distance sensor detects object proximity, and optional capacitive pads on the back of the hand enable richer H.R.I. interactions.
Robot integration
The manipulator ships with an open-source ROS package, a Python (PyPot) library and a low-level UART serial protocol. Interfaces include UART over RS485 (or TTL compatible with Robotis systems), USB for configuration and maintenance, and optional Bluetooth. An ISO 9409-1-50 mounting adapter fits most robot arms.
Classification
5-finger hand · serves as: End effector, Gripper, Manipulator.
