SLIDER-TYPE WIRE DRIVER FOR UNDERACTUATION AND GLOVE-TYPE WEARABLE ROBOT COMPRISING SAME

Title:

SLIDER-TYPE WIRE DRIVER FOR UNDERACTUATION AND GLOVE-TYPE WEARABLE ROBOT COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2020/218804

Kind Code:

A3

Abstract:

The present invention relates to a slider-type wire driver for underactuation and a glove-type wearable robot comprising same and, more specifically, to a slider-type wire driver for underactuation and a glove-type wearable robot comprising same, wherein the wire driver has a structure appropriate for driving a robot in an underactuation type, and the structure is simple and enables effective operations. The slider-type wire driver for underactuation and the glove-type wearable robot comprising same, for the purpose of accomplishing the above-mentioned objective, are advantageous in that friction between a wire and components near the wire is effectively reduced, thereby facilitating operations of the underactuated robot and increasing the life thereof. In addition, the slider-type wire driver for underactuation and the glove-type wearable robot comprising same, according to the present invention, are advantageous in that an actuator for applying a tension to the wire for the purpose of underactuation can be fabricated at a low price.
