1. A legged robot, comprising:
a frame comprising a plurality of links in mechanical communication with plurality of brackets, the frame forming a front, back, top, bottom, and sides;
four legs, each leg removably mechanically coupled to one or more of the plurality of brackets, each leg mechanically attachable and detachable to the bracket by a user via a mechanical fastening mechanism;
each leg comprising a sealed motor enclosure at a proximal end of the leg, the sealed motor enclosure at least partially enclosing an abduction motor having an abduction output mechanically coupled to the frame, and the sealed motor enclosure at least partially enclosing a hip motor mechanically coupled to the abduction motor;
each leg further comprising a knee motor external to the sealed motor enclosure and mechanically coupled to a hip motor output of the hip motor;
a computer module in mechanical communication with one or more of the plurality of brackets and in electrical communication with the legs; and
a power module in mechanical communication with one or more of the plurality of brackets and in electrical communication with the legs and the computer module.
