dc.description.abstract A piezoelectric inchworm motor is developed for battery powered unmanned aerial vehicles where energy efficiency is critical. The motor comprises two stationary clamps and a moving extender, which uses two piezoelectric stack actuators in push-pull mode with a displacement amplification mechanism. The effect of internal compliance and its effect on the load capacity are investigated. A switching converter is used to provide the voltage supply, and switching amplifiers are used to drive the piezoelectric stacks. These were designed for efficiency, weight and reliability. en
