Investigation of load and strain sensing functions of flow-direction reversal device

Abstract

Soft robots enable various functions with their simple structure. However, typical flow control using many solenoid valves increases the complexity, mechanical structure, and cost of the control system. To address this issue, in our previous study we developed a device reversing the flow direction, switching blowing and suction with a single air flow control. In addition, we found the device can be used as force and strain sensor. In this study, we investigated the sensing functions.
