US Patent 11369868 Motion generator

This invention relates to motion generators comprising: an end effector, a stationary support, a first set of elastic elements interconnecting the end effector and the stationary support; a set of tensile members; in which the end effector is supported within the stationary support by the elastic elements; and a set of actuators in which the motion generator further comprises at least six rockers each rocker being pivotally mounted at one end thereof on the stationary support, and each rocker having a free end; the set of tensile members comprising: at least six elongate tensile members, each elongate tensile member having one end connected to a rocker and the other end connected to one of a second set of elastic elements which are fixed; a set of connecting elements connecting each rocker to the end effector and in which each one of the set of tensile members is independently adjustably tensioned by an associated actuator to move the free end of the rocker, which rocker movement causes movement of a connected connecting element leading to movement of the end effector.
