Abstract
We proposed a novel bio robotic application which has almost the same dynamics as that of the neuromuscular control system to understand biological systems. This bio robot consists of culture neuronal network and muscle-powered actuator to mimic living creatures. Through the computer, culture neural activities are transported to muscle-powered actuator as electrical signals, and muscle activities are fed back to culture neurons as motion capture images. Living neurons were cultured on multielectrode array to measure neural signals. Living muscle tissues were engineered from muscle cells as driving source of the actuator. A SU-8 microgripper, which was fabricated as a structure of muscle-powered actuator, was assembled with a living muscle tissue. We successfully controlled the muscle-powered SU-8 microgripper with electrical stimulation mimicked neural signals. Moreover, we could construct real time motion feedback system of muscle-powered actuator with optical flow.
