Description
CAD model of the Dynamic Robotic Actuator (Dyrac). The Dyrac actuator was developed in the frame to reproduce human hammering motions in a teleoperation scenario. The design requirements were were a stiffness changing time of 50 ms, a peak output velocity of 20 rad/s, and variable damping.
Performance measurements on the prototype showed an effective stiffness changing time of 50-120 ms for small to large stiffness steps, nominal output velocity of 16 rad/s, and a variable damper with a damping torque of 0-3 Nm.
Its effective stiffness range is 0.2-313 Nm/rad.
