Design of motor driver circuit for unconstrained poppet valve and its implementation to flexible circuit

Abstract

In recent years, the application of pneumatic actuators has been progressing not only in the industrial field but also in the medical and welfare fields. However, general pneumatic valves are large and difficult to incorporate into robots. Therefore, a unconstrained poppet valve, which is a small pneumatic valve, was developed. At present, the driving system of the unconstrained valve is larger than the valve, and the driving system needs to be smaller. Here, we verified the design of circuits using motor drivers to replace conventional drive circuits. We fabricated the circuit boards made of soft materials for incorporation into robots.
