Biomimetic actuator control system
Patent no.: 10,154,915
Inventor(s): Kiisa Nishikawa, John Tester, Jeremy Petak
Description: This technology relates to a novel bio-inspired control algorithm based on the winding filament hypothesis that emulates the intrinsic properties of muscle that characterize biological actuation. The algorithm consists of a computer simulation of a motor in series with a spring. A movable pulley is positioned between the motor and the spring. The motor can extend the spring, and forces that move the pulley can also extend or shorten the spring. The algorithm demonstrably captures the non-linear properties of muscle during active stretch and shortening.
Potential applications: The primary application is as a robust control algorithm for control of powered prostheses.
Benefits and advantages: The relative advantages of the novel device over existing control systems include a robustness on ramps, uneven terrain and on compliant substrates.
