DRIVING DEVICE HAVING ELASTIC MEMBER FOR CONNECTING INPUT AND OUTPUT

WIPO Patent Application WO/2020/101053

A1

An embodiment of the present invention provides a driving device having an elastic member for connecting input and output. The driving device includes: a motor; a gear module connected to the motor; an elastic member which is provided in vicinity of the gear module, and receives power transferred from the gear module; an output unit which is connected to the elastic member and acts upon an external load; an input position feedback unit which is connected to the elastic member or the motor so as to avoid interference with the gear module; an output position feedback unit which is connected to the output unit and extends to the vicinity of the motor so as to avoid interference with the gear module; and a sensing module. The sensing module is provided in the vicinity of the motor so as to avoid interference with the gear module, and senses the deformation of each of the input position feedback unit and the output position feedback unit caused by the deformation of the elastic member when the output unit acts upon the load.
