DEVELOPMENT OF JUMP ASSIST SYSTEM USING PNEUMATIC RUBBER MUSCLE

In this paper, we develop a jump assist system that can generate instantaneous force using pneumatic artificial rubber muscles (PARMs) since such quick motion is required in the rescue activities. The device extends the knee joint using PARMs. Moreover, bi-articular mechanism between the knee and ankle joint is realized using PARMs. Assist timing with the device is detected with an acceleration meter installed in the device. The timing is investigated both theoretically and experimentally. The experiments are performed with three subjects to demonstrate the effectiveness of the device.
