Shadow EDC Hand Release
New Version of the Shadow Motor Hand Released
The new EtherCAT Dual CAN (EDC) hand sees a sizeable increase in performance for the world leading Shadow Dexterous Hand.
The EDC version of the motor hand is identical to a standard CAN bus motor hand, except that the single CAN bus which serves all of the electronics has been replaced by an EtherCAT network and two CAN buses.
A CAN bus has a bandwidth of about 600kB/s, allowing a servo rate of about 100Hz internal to the hand.EtherCAT has a bandwidth of 7.5MB/s, allowing a servo rate of 1000Hz.
The following table shows the performance of the new EDC hand compared to the CAN hand in various areas:
| CAN hand | EDC hand | |
|---|---|---|
| Sensors | ||
| Joint Sensor update rate | 100Hz | 1000Hz |
| Tactile Sensor update rate | 100Hz | 1000Hz |
| Motor Torque Sensor update rate | 30Hz | 500Hz |
| PID Control Loops | ||
| Torque control loop rate | 1000Hz | 5000Hz |
| Position control loop rate | 100Hz | 1000Hz |
| Velocity control loop rate | - | 1000Hz |
| Torque Controlled at | Motor | Motor |
| Position Controlled at | Motor | Host |
| Other Features | ||
| Friction Compensation | No | Yes |
| Firmware bootloading | No | Yes |
| 6-axis IMU | No | Yes |
You can order a Shadow Robot hand as a pneumatic or motorised system.

The Shadow Hand has integrated sensing and position control, allowing precise control from off-board computers, or integration into your existing robot platform.
The Shadow Hand contains an integrated bank of 40 Air Muscles which make it move. The muscles are compliant, which allows the Hand to be used around soft or fragile objects.
The Shadow Hand can be fitted with touch sensing on the fingertips, offering sensitivity sufficient to detect a single small coin.
