The disclosure provides example apparatus and methods for automatically adjusting a socket size of a prosthesis. The apparatus includes (a) the prosthesis having a socket configured to receive a limb, (b) a first opening in a socket wall, (c) a first panel aligned with the first opening, (d) a first actuator coupled to the first panel and to the prosthesis, the first actuator is configured to advance and retract the first panel, (e) a first sensor coupled to the socket wall and configured to obtain limb-to-socket gap data, and (f) a processor coupled to the first actuator and the first sensor, wherein the processor is configured (i) to receive the limb-to-socket gap data, (ii) to determine a socket-size adjustment based on the limb-to-socket gap data and a predetermined socket-fit value, (iii) to generate and (iv) to send a command with the socket-size adjustment to the first actuator.
