Bodyware - Actuation

    Following the general idea of moving from traditional to “soft-bodied” robots, we work on the improvement and development of the technology of actuation. In particular, we are considering high-efficient custom-designed electric motors (brushless) and new gear structures but simultaneously high-risk activities in the field of electro-active polymers (EAP) and carbon nanotubes [see also Materials].
