Abstract
A device is provided to allow adaptation of a prosthetic or robotic foot in the medial-lateral direction, including pronation and supination of the foot using a series of articulations. Articulations are permitted in the disclosed device due to linkage systems positioned at various locations of the prosthetic foot. In particular, the device includes multiple connected linkage systems each including upper and lower portions with an articulating contact surface designed for load carriage and stability. The point of contact between the contact surfaces of each linkage system comprises the position-dependent instantaneous center of rotation of the upper portion with respect to the lower portion. The device also includes a platform coupled between the linkage systems and a base.
