Abstract
In this paper, we describe 3-way unconstrained vibrational pneumatic poppet valves. Wearable robots need many pneumatic valves to drive McKibben actuators. Thus, it is important to miniaturize these valves. We develop unconstrained vibrational pneumatic poppet valves with PZT drivers. We need supply and exhaust valves to drive one MaKibben actuators. In this paper, two valves were integrated for one actuator. Experiment showed that our 3-way valves could supply enough flow rates. We check the flow rate for various cases of the exhaust valve. Additionally, we check the influence between the supply base and exhaust case by sandwiching the tube between two valves.
