Abstract

The aim of this project is the examination of shape memory alloy (SMA) based actuators in walking robots. Since the power-mass ratio of SMA’s is extremely high compared to typically used actuators (hydraulic, pneumatic and electric motors), it is reasonable to try SMA’s in robot applications as well. The experiments resulted in a biped walking robot (SILENT1) that is moved via shape memory alloy based actuators.
