Abstract
A temperature-driven mechanical system includes a first effector, made of temperature-induced shape-changing material, having first and second ends and a longitudinal axis running through the ends, as well as a suspension system that mounts an assembly including the effector, to support rotation of the assembly about the longitudinal axis. The suspension system has a first rotational limit stop associated with a first angular position of the assembly at or below a first temperature limit and a second limit stop associated with a second angular position of the assembly at or above a second temperature limit. An array of such systems is similarly provided.
