Hand-Lite – almost all the capability of a Dexterous Hand in a smaller, lighter, cheaper package.
The Shadow Hand Lite keeps the human-like kinematics of its big brother, but removes the little finger and wrist. The size and shape is otherwise the same as a normal male human hand, down to finger lengths and tip positions.
- 13 Degrees of Freedom across 16 Joints:
Independent control of each finger for high dexterity
3 Fingers: each with 3 Degrees of Freedom (DoF)
Thumb: 4 DoF
(No wrist or little finger)
- Weight: 2.4 Kg, Payload 4 Kg.
10N force at the finger tips makes Hand-Lite able to handle a wide range of objects
Smaller and lighter than the Shadow Dexterous Hand – Fits a wider range of platforms
- EtherCAT Communications:
100Mbps bus for fast data sampling and control loops
Fully supported in ROS – The Robot Operating System (www.ros.org)
16 joint position sensors, 26 tendon strain gauges, 13 motor current and temperature sensors: plenty of sensor data for multiple configurations and experiments.
- Tactile Sensing:
Fingertip single channel analog response sensors included as standard. Hand Lite can be upgraded with a number of other tactile sensor options (e.g. Syntouch’s BioTac®)
The lighter Hand Lite can be integrated on a wider variety of robot arms. Mounting plates for attachment are included.
The new Shadow Hand Lite puts the full dexterity of the Shadow Hand design into a smaller, lighter, and cheaper package. By removing a finger and the wrist, and shrinking the forearm, Shadow’s engineers have produced a compact yet highly capable dexterous manipulator for the wider world. This new Hand has been developed to bring dexterity and manipulation to areas where five-fingered motion is not needed, but the flexibility and dexterity of the human hand is desired.
