Abstract:
The biologically inspired, wearable, exo-muscular suit has been proposed as a cost-effective, fluidly actuated device for lower-limb physical therapy as well as for assistance with activities of daily living. The exosuit, actuated with 12 biomimetic Hydro Muscles independently controlled with 12 5-way inexpensive, off-the-shelf,
on-off solenoid valves, has been designed, manufactured, and tested on a lightweight, biomimetic human skeletal model. The results from testing suggested a necessity for more advanced fluid flow management support system in the form of affordable, lightweight, and compact valves suitable for robotics applications. To meet these metrics and fulfil the requirements of the exosuits fluid flow management system the Compact Robotic Flow Control Valve was designed, manufactured, and tested. The CRFC Valve is lighter, more compact, more controllable, and less expensive than any other similar valve currently on the market.
