Abstract: An underactuated exoskeleton for lower-limbs, for supporting the knee of a user, includes a first and a second coupling frame and a movement means associated with the first and with the second frame configured to confer to the second frame a roto-translation movement with respect to the first frame or vice versa. The exoskeleton further includes a junction means operatively interposed between the movement means and the first frame and/or the second frame configured to allow a relative rotation between the first and the second frame in a second plane, orthogonal to the first plane, a rotation of said second frame about said main axis of the leg and a relative translation between the first and the second frame in the second plane.

Abstract: An electronic measurement unit for a polymorphous device, comprising a number of lateral structures, each lateral structure including: a support structure; at least one sensor constrained to the support structure and generating an electrical signal indicative of a deformation of the support structure; and a coupling structure that constrains a corresponding external covering element to the support structure in a releasable manner, so that when the external covering element is constrained to the support structure and an external force acts on the external covering element, the electrical signal is indicative of the external force.
