Development of Low-cost Pressure Control Type Valves Using Buckled Tubes and Gate-mechanism

In the pneumatic driving system for a soft mechanism, control valve is most heavy and expensive device. To realize compact inexpensive system, it necessary to reduce size, weight, cost of valve. previous study, low-cost flow rate type servo valves, that uses buckled tubes gate mechanism in an analog way, were proposed tested. However, these drift overlap zone was observed owing plastic deformation lower stiffness frame. Ideally, feedback using fluidic parameter output useful solve this problem. there no sensor market. paper, pressure consists transducer on-board tiny-embedded controller, The construction operating principle both valves have been described. performance tested has also reported. As result, can be confirmed according desired voltage. dynamic
