Abstract
A computer-controlled parallel-leg mechanism, with three pairs of remotely-actuated tendon legs, provides accurate six-degrees-of-freedom motion and positioning for a tool platform. Leg pair termination at a common point with three degrees of pivoting freedom is provided by a unique linkage joint. Non-intrusive tool-position feedback is enabled by nine shaft encoders mounted at the mechanism's base end.
