摘      要：Conventional single-DOF mechanism is being increasingly replaced by multi-DOF mechanism with multi-actuator that leads to *** there are many cases where the flexibility is redundant,programmable mechanisms provide a cost-effective solution with limited *** paper discusses the inverse kinematics of hybrid driven seven-bar mechanism,which is a programmable *** study is to make the mechanism work as a set of mechanical cam *** inverse kinematics model is presented to model the mechanism servomotor *** simulations and experiments,it is proofed that (a) the hybrid driven seven-bar linkage has programmable cam curves,and (b) the programmable cam mechanism is feasible.
