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.

Abstract: A robotic hand is provided including a main body defining the body of the robotic hand and a longitudinal axis; a finger hinged to the main body; an attachment defining the attachment surface for attaching to an external member; and a hinge defining a mutual rotation axis between the attachment and main body so as to vary the angle between the longitudinal axis and the normal to the attachment surface.
