Seed Robotics RH8D Adult Dexterous Robot Hand — with Fingertip Force Sensors

The Seed Robotics RH8D is an adult-size anthropomorphic robot hand with 19 degrees of freedom driven by 8 internal smart actuators. This configuration adds fingertip force sensors — the configuration used in the SenseGlove R1 teleoperation demonstrations, because the fingertip force channel is what gives a haptic glove usable tactile data to feed back to the operator.

Specifications

• 19 DoF driven by 8 internal smart actuators
• Three-segment fingers with opposable thumb and full spherical wrist joint
• 620 g; 2.5 kg vertical pull payload, 1 kg in free 3D space
• 9-24 V supply; 32-bit ARM Cortex M4 with a dedicated co-processor per actuator
• RS-485 UART, Dynamixel Protocol 1.0 and 2.0 compatible, plus USB and optional Bluetooth
• Open-source ROS package, Python (PyPot) support and URDF simulation models
• Palm time-of-flight distance sensor plus per-actuator position, speed and current feedback
• Fingertip force sensing down to 1 mN / 0.1 g resolution

Integration

Pairs with SenseGlove R1 for force-feedback teleoperation and imitation-learning data collection. Mounts to collaborative arms via a standard tool flange. Knoxlabs configures firmware, licences and adapters before shipping.
