Abstract: A physical Human-Robot Interface (pHRI) is configured for a passive lumbar exoskeleton that aids an operator in exerting effort. The pHRI includes connections to the operator's body using a posterior corset, lumbar belt, posterior support belt, and thigh cuff. The pHRI features rigid kinematic structures with passive degrees of freedom (pDOFs) that prevent displacements in the human-machine interface that could lead to misalignments of the joint rotation axis. The pHRI incorporates two posterior struts that bypass the human multi-articular kinematic chain of the lower and middle back, connecting the pelvis to the torso bilaterally and transferring assistance from the exoskeleton to the body. Additionally, the pHRI has linkages between the posterior struts and the rigid corset to ensure effective transmission of assistance.

Abstract: An upper-body sensorized exoskeleton is configured to interface with external systems, such as FES, advanced cognitive systems, and VR/AR interaction programs, in order to facilitate rehabilitation and assistance of patients affected by upper-limb impairments. The sensorized upper limb exoskeleton delivers anti-gravitational support at the shoulder level, enables upper-limb configuration limits for shoulder and elbow ranges of motion, and reads kinematic data that may be analyzed by users and clinicians. The sensorized upper limb exoskeleton is equipped with electronic processing and communication means that support bidirectional communication between exoskeleton and external systems.

Abstract: 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.

Abstract: A passive lumbar exoskeleton for assisting an operator in exerting efforts includes a compensation device arranged to provide assistive forces at a hip joint of the operator and a human-machine interface configured to secure the compensation device to the operator. The compensation device comprises an assistive torque assembly with a thigh link rotatably connected thereto. The thigh link defines a thigh cuff engageable by the operator to impose resistive moments on the compensation device. The assistive torque assembly comprises extension and flexion stop surfaces to define an allowed degree of motion for the compensation device, a transparent range mechanism defining a range of motion wherein the operator can move about with no assistive forces applied, and an assistance regulation device arranged to adjust the degree of tension in an elastic mechanism.
