Foundation Technologies

Actuators

The integrated actuation units feature high torque and power density. The passive compliance renders them sturdy as well as capable of high fidelity torque sensing and control. Both features permit human-like soft but also harsh physical interaction with the environment. The actuators feature hard real-time interfaces. They are modular and customizable. The existing actuator palette covers a broad power and torque range (see info sheet).
