Objective
Serial or parallel elastic drives (SEA, PEA) are useful when energy efficiency, controllability and human-machine interaction are important. This drive topology uses elastic elements in the torque or force flow, which can be arranged serially, i.e. directly in the force flow, or parallel to it - for example to compensate for the weight force.
At the IMT, drives with about 20 W power and the widest possible frequency bandwidth (up to 500 Hz) are to be set up and characterised. Test benches and measurement infrastructure are available for this purpose.
