A rotational joint of intra-extra rotation for assistance of the movement of intra-extra rotation of a shoulder of a user. The rotational joint features a first circular guide arranged to rotate about a first rotation axis and a second circular guide arranged to rotate about a second rotation axis that is parallel to the first rotation axis. A support element is arranged to support the first and the second circular guides. The first and the second circular guide are pivotally connected by a conical wheel having a third rotation axis perpendicular to the first rotation axes and said conical wheel being pivotally constrained to the support element.

Exoskeleton for upper arm

An exoskeleton includes a frame; and an actuation system. The actuation system includes a transmission device; a passive joint mechanism connecting the frame to the transmission device, the passive joint mechanism having a four-bar linkage; and a drive system couples the passive joint mechanism to the transmission device, and is arranged to drive the transmission device.

A system for assisting an operator in exerting efforts comprises a garment that can be worn by the operator, which is to engage, when worn, the mutually mobile parts of a joint of the operator. The system defines at least one axis of rotation that is to assume a position corresponding to the joint of the operator. A device is carried by the garment and designed to operate so as to compensate the resistive moments that act on the joint during the effort exerted by the operator. A compensation device is provided equipped with a rotational assembly, which has a neutral position and is able to determine a pre-set plot of the assisting torque that is a function of the angle of rotation of the joint. The compensation device may include a tension regulation device to regulate a moment obtained about the joint of the operator.

System for assisting an operator in exerting efforts

A system for assisting an operator in exerting efforts comprises a frame having one or more degrees of freedom and supporting a compensation device arranged to provide assistive forces to a joint of the operator. The compensation device comprises a regulation device comprising a motor arranged to adjust a degree of tension in an elastic mechanism. The regulation device receives instructions from a control system based on information obtained from an encoder or the operator's preferences recorded at a control panel.

Ergonomic exoskeleton system for the upper limb

A monolateral actuation system of a hip articulation is configured to be connected to an orthosis. The monolateral actuation system comprises a motor device arranged to provide assistive torque at a motor axis; a transmission device is connected to the motor axis and arranged for transferring the assistive torque onto an output axis corresponding to an axis of flexion-extension of the hip articulation and parallel to the motor axis. The transmission device includes a cable and first and second pulleys connected to one another by the cable. The first and second pulleys are arranged to extend relative to one another variably. A fixed frame is provided for connecting to the orthosis onto which the motor device and the transmission device are mounted.
