By applying voltage to a piezoelectric material, you can make it change its shape. Through the clever design of the Piezo LEGS® ceramic actuators, each of the motor “legs” can be elongated as well as bent sideways. With appropriate drive signals, you can create synchronized movement of each pair of its four legs, and it will begin to walk just like an animal would – step by step, and stopping at any instance on a nanometer level. The direct friction coupling between legs and drive rod means Piezo LEGS® will operate without the slightest backlash or mechanical play. The direct drive also gives full force, power-off locking without any power consumption.
