Feasibility of a Hydraulic Power Assist System for Use in Hybrid Neuroprostheses

Figure 2

PAS bench testing setup. The PAS hydraulic circuitry is connected to the rotary actuator consisting of right hip cylinder (RHC) connected between the exoskeleton upright and rack and pinion transmission to transmit torque. The upright is attached to a Biodex dynamometer to measure flexion torque. Pressure, torque, angle, and angular velocity data are read into an xPC Simulink real time environment.
