The worm gear is configured to be operably coupled to the leg support, and the worm and the worm gear are configured to transfer rotary motion from the motor assembly to the leg support upon initiation of a force applied to the leg support.

A method of controlling a mobility device and related device including at least one actuator component that drives at least one joint component is described. The control method may include executing a control application with an electronic controller to perform: receiving a command in the control system of the mobility device for initiating an automated assessment and adjustment protocol; controlling one or more mobility device components to perform the automated assessment; electronically gathering user performance data associated with the automated assessment and determining user performance metrics; and electronically controlling one or more of the mobility device components in accordance with the performance metrics. The automated assessment includes controlling mobility device components to perform a predetermined assessment activity related to performance of the mobility device and/or user. Automatic adjustments to the device components, including adjusting tension and resistance levels of the joint components, may then be made based the performance metrics.

The present disclosure includes a robotic exoskeleton comprising a back portion providing at least two degrees of freedom, two shoulder portions, each shoulder portion providing at least five degrees of freedom, two elbow portions, each elbow portion providing at least one degree of freedom, and two forearm portions, each forearm portion providing at least one degree of freedom. The present disclosure may also relate to associated robotic forearm joints and robotic shoulder joints.

A passively balanced load-adaptive upper limb exoskeleton. An upper arm (A), an elbow (B), a forearm (C), and a hand (D) are arranged sequentially from left to right. An upper arm upper rod (A1) and an upper arm lower rod (A2) each are hinge-connected to an upper arm elbow housing via a bearing. A forearm upper rod (C1) and a forearm lower rod (C2) each are hinge-connected to a forearm elbow housing via a bearing. An upper arm support rod (E) is disposed between an upper arm driving mechanism (A4) and an upper arm elbow assembly (B1). One end of the upper arm support rod is fixedly connected to two upper arm support rod slide blocks (9) in the upper arm driving mechanism, and the other end thereof is hinge-connected to protruding shafts on two sides of an upper arm lead screw nut connection member via bearings. A forearm-upper arm support rod is disposed between a forearm driving mechanism (C4) and a forearm elbow assembly (B2). One end of the forearm-upper arm support rod (K) is fixedly connected to two upper arm support rod slide blocks in the forearm driving mechanism, and the other end thereof is hinge-connected to protruding shafts on two sides of a forearm lead screw nut connection member via bearings. The hand is hinge-connected to a wrist. The upper limb exoskeleton of the invention is used to facilitate handling of heavy goods or carrying of certain items.

Disclosed is an exoskeleton-type rehabilitation robot system, including: a body part provided on a chair in which a user sits and provided with a robot arm capable of moving left or right based on the user seated on the chair; a conversion part configured to convert a position of the robot arm with respect to the body part; a driving part configured to articulate the robot arm with respect to the body part; and a controller configured to detect a change in a position of the robot arm and control a left or right driving mode of the driving part according to the position of the robot arm. In accordance with such a configuration, the exoskeleton-type rehabilitation robot system of the present invention is provided integrally with a chair, thereby having excellent space utilization. In addition, the user's initial preparation for rehabilitation training is simple, which can improve efficiency.

A robotic exoskeleton including a back portion providing at least two degrees of freedom, two shoulder portions, each shoulder portion providing at least five degrees of freedom, two elbow portions, each elbow portion providing at least one degree of freedom, and two forearm portions, each forearm portion providing at least one degree of freedom.

A seat massage system includes a substrate; a driving assembly, a power delivery assembly; a rail base including a guide groove provided on an internal surface, the guide groove including a first portion close to the substrate and a second portion farther from the substrate; a moving base provided on the corresponding one rail base, receiving driving force from a corresponding power delivery assembly, provided with a guide member, and sliding along the guide groove; and a massage head member provided at a front end of the moving base, where the power delivery assembly drives the corresponding moving base to rotate relative to the rail base by the driving of the drive assembly, and at the same time causes the moving base to linearly move in forward and rearward direction through coupling of the guide member and the guide groove, and controls to control the moving base to stop at a predetermined position.

An orthosis provides a wearer at least one of forearm supination, forearm pronation, shoulder internal rotation, shoulder external rotation, shoulder adduction, shoulder abduction, shoulder flexion, shoulder extension, elbow flexion, and elbow extension. It includes a shoulder assembly adapted to be secured to a wearer's shoulder and an upper arm assembly connected to the shoulder assembly and adapted to be secured around a wearer's upper arm. The upper arm assembly defines an upper arm assembly axis. A wrist assembly is adapted to be secured around a wearer's wrist. The wrist assembly defines a wrist assembly axis. A splint arm assembly includes an upper splint arm, a lower splint arm, and a pivot pivotally connecting the upper splint arm to the lower splint arm. The upper splint arm adjustably connects to the upper arm assembly and the lower split, arm adjustably connects to the wrist assembly.

A pull type rotary massage nozzle sequentially includes a nozzle holder, a nozzle core seat, a nozzle surface cover, and a nozzle core assembly. The nozzle core seat is detachably mounted on the nozzle holder. The nozzle surface cover is fixedly mounted on the nozzle core seat. The nozzle core assembly is mounted in the nozzle core seat and may circumferentially rotate about a mounting axle relative to the nozzle core seat and the nozzle surface cover, and may also axially float or sink along the mounting axle relative to the nozzle core seat and nozzle surface cover. The nozzle surface cover is provided with a static torsion rib. The nozzle core assembly is provided with a dynamic torsion rib. The dynamic torsion rib is selectively engaged with or separated from the static torsion rib along with floating or sinking of the nozzle core assembly.
