Contents Intro.

Actuators play key roles in robotics. Robotic and mechatronic devices used for rehabilitation and biomedical applications require new actuators that are expected to be fast, zero backlash, silent, and energy efficient, and compact. In this talk the concept of cellular piezoelectric actuators and the latest research work will be presented. The cellular actuator concept is to connect many small actuator units in series or in parallel, and composes in totality a single actuator array. Piezoelectric actuators using exponential strain amplification mechanisms produce over twenty percent effective strain that is comparable to natural skeletal muscles. Stochastic broadcast control coordinates a vast number of units in the actuator array, which drastically improves wiring and addressing issues. A newly proposed "fingerprint" method characterizes complicated actuator array topologies.
