Joint positioning device and method of operating the same

Joint positioning device for easy fit adjustment

This technology relates to a joint positioning device and its operating method, allowing users to adjust the force transmission points of a wearable robot to fit their body simply by operating a knob.

Conventional wearable robots require wires or webbing to be attached to precise points on the body to ensure performance, which has historically been inconvenient due to the need to manually adjust multiple straps and fasteners.

This technology enables intuitive position adjustment through a joint device consisting of adjustment elements and a knob, reducing preparation time and improving the reproducibility of assistive performance.

Key Features:

• A support frame featuring multiple through-holes spaced at specific intervals along its length to serve as a reference for positioning.
• A slider frame mounted to slide along the length of the support frame for length adjustment.
• A link oriented perpendicular to the support frame, featuring a gear along the circumference of its lower outer surface.
• A knob that locks the link's rotation by engaging with the gear in fixed mode and releases it in adjustment mode.
