The FitSocket is a robotic residual limb measurement device that allows for the quantitative production of prosthetic sockets. Sockets — the cup-shaped devices that attach an amputated limb to a lower-limb prosthesis — are made through unscientific, artisanal methods that do not have repeatable quality and comfort control from one individual with amputation to the next.

The FitSocket project aims to identify the correlation between leg tissue properties and the design of a comfortable socket. The FitSocket is a robotic socket measurement device that directly measures tissue properties. With this data, we can rapid-prototype test sockets and socket molds to make rigid, spatially variable stiffness, and spatially/temporally variable stiffness sockets that are much more comfortable than conventional sockets.
