Upper Extremity Actuation
For early prototypes, I worked with materials often used to make custom fit orthotics. I integrated this with an actuator precisely sized for the desired range of motion and an early strapping concept. This was used for early user testing before CAD Modeling.
Rev.2 of the Elbow System included a fully integrated housing for electronics, valves, and actuation. Cut outs reduce the weight of the device and improve breathability, reducing heat.
Strapping was designed to be easily detachable while still comfortable and effective. The latest strapping configuration was made to simulate wrapping. This was influenced by research done to find the lines of non-extension at the skin's surface.
Lower Extremity Actuation
This image depicts two adults, one in the 5th percentile and the other in the 95th percentile. The hug wall needed to be designed to accommodate both.
