Abstract: A robotic assembly comprises a first joint comprising first and second support members rotatably coupled together, and a joint position restoration assembly coupled to at least one of the first or second support members. The joint position restoration assembly can comprise a first spring and a mechanical linkage, wherein the joint position restoration assembly is operable to apply a restoring torque to the first joint. The joint position restoration assembly can be configured to provide a restoring torque versus joint position profile relative to the first joint that corresponds to known mass properties of at least a portion of the robotic assembly acting on or otherwise associated with the first joint, such that, when the first joint is not undergoing powered actuation, the joint position restoration assembly operates to apply, based on the profile, the restoring torque to position and to support the first joint in a stable support position.

Abstract: A walking assisting system for a user. The system includes first and second sub-systems each having at least one optical sensor, for example a camera. The first sub-system is fitted to the user's abdomen region, for example waist, and the second sub-system is fitted to the user's head region, for example eyes. The system is arranged to align between data obtained from optical sensors of the first and second sub-systems in order to indicate to the user presence of obstacles detected by the first sub-system in a coordinate system of the second sub-system.
