A foot for a robotic exoskeleton includes three rigid foot segments, namely a middle foot segment arranged to be connected to a leg of the robotic exoskeleton, a front foot segment elastically connected to the front end of the middle foot segment by a first set of leaf springs and a rear foot segment elastically connected to the rear end of the middle foot segment by a second set of leaf springs. The foot has laces for fastening the foot to a person's shoe. In the condition where the front foot segment and the rear foot segment are both in contact with the ground, and no load is applied onto the foot, the middle foot segment is not in contact with the ground, but is elastically suspended by the first and second sets of springs.

Foot for a robotic exoskeleton for assisted walking of persons suffering from locomotor disorders

An actuation device () comprising a threaded shaft () connected at one end to driving means adapted to allow the threaded shaft () to rotate about its longitudinal axis (a). A movable element () is provided with a cylindrical cavity () adapted to receive the threaded shaft (), and configured so that a rotation of the threaded shaft () corresponds to a translation the movable element () along the longitudinal axis (a). The device () has two guiding rods (') coupled to the movable element () and adapted to constrain the translation of the latter along a direction parallel to the longitudinal axis (a). Element () comprises a first () and a second () element constrained to each other, wherein the first element () is coupled to the threaded shaft () and the second element () is coupled to the two guiding rods (&#x2032;).
