Tethered robots often experience entangling of their cables with obstacles in uncertain disaster environments. This paper proposes a spherical tether handling device that unfastens a robot's tether during surveys by releasing the tether and carrying it aside. By using a differential mechanism, the device drives shells and rollers that hold the tether. On flat surfaces, the device moves forward by...
The purpose of this study is to establish a quantitative method that can evaluate the motor function of human lower limbs in dynamic situations. As an index of motor function, we focus on the mechanical impedance characteristics of the lower limbs. By controlling these characteristics, humans can improve motion stability and adapt their movement to disturbances in the environment. In this paper, we...
To break out of a debilitating cycle caused by his deterioration of his ability, a patient participates in rehabilitation programs and actively rehearses his degraded abilities. A Cycling Wheel Chair (CWC) provides a rehabilitation option for preventing one's legs weakening and/or nervous system atrophy.
