Abstract: A prosthetic feedback device to be associated with a prosthesis equipped with a motor for controlling the same prosthesis is provided The device includes an attachment body configured to be in direct contact with the user; at least one air chamber interposed at least partially between the body and the user; an inflation circuit for inflating the chamber; and a circuit board to control the inflation of the chamber by the motor.

Abstract: A robotic foot, to rest on a support surface and including: an attachment to an external object; a chain defining a contact area with the support surface; a first arm constrained to the chain at a first end of the chain and hinged to the attachment; a second arm constrained to the chain at a second end of the chain and hinged to the attachment; and elastic member adapted to reciprocally spread the arms keeping the chain taut and opposing a deformation of the chain when in contact with the irregular support surface.

Abstract: A robot including a limb including a robotic foot defining a contact area to a resting surface and an anchoring body of the robotic foot; a motor for moving the limb and a control unit for the motor; the robotic foot includes an attachment to the anchoring body; a contact member defining the contact area; a joint block of the contact member to the attachment including a first hinge between the contact member and the attachment, a second hinge between the contact member and contact and attachment; an additional hinge between attachment and joint block; at least one sensor for measuring a rotation; an additional sensor for measuring the additional rotation; and the control unit is configured to drive the motor according to the measurement of the rotations.
