Independent pneumatic-driven quadruped robot works by a Wankel-type rotary engine-driven compressor

Abstract

The power sources of mobile robots are generally chosen from electric drive, hydraulic drive, and pneumatic drive. In this study, we focus on the pneumatic drive. The pneumatic drive has advantage of shock absorption and light weight comparing with other sources, but the compressor for small robots which has enough pressure and flow have not been developed.in this study, we develop a Wankel-type rotary engine-driven compressor that can generate high-pressure, large-flow compressed air suitable for installation on small robots. In addition, we also develop a pneumatic-driven four-legged robot that can be driven with a Wankel-type rotary engine-driven compressor, aiming to complete an independent pneumatic-driven robot.
