Abstract :
The control of a dynamic system with multiple degrees-of-freedom (DOF) is far simpler if the system is uncoupled. The property of an uncoupled system can be achieved with careful design of mechanical structures in the case of conventional mechanisms. The study reported in this paper will show via experiment the uncoupling property in a compliant mechanism, which is driven by three PZT actuators. This observation has the significance to motivate study on a new methodology for designing uncoupled multi DOF compliant mechanisms.
