Title:
ACTUATOR MODULE HAVING DUCTILE PART
Document Type and Number:
WIPO Patent Application WO/2019/164037
Kind Code:
A1
Abstract:
The present invention relates to an actuator module having a ductile part and, more specifically, to an actuator module having improved intrinsic stability, the actuator module being mounted on a robot that comprises multiple joints and having a ductile part capable of sensing an abnormal load through a sensor-based accurate load measurement. One embodiment of the present invention provides an actuator module comprising: a driving part for generating rotational force; a speed reducing part connected to the driving part so as to receive the rotational force, and reducing the received rotational speed so as to increase the rotational force; a ductile part connected to the speed reducing part so as to receive the rotational force, and formed in a shape in which a plurality of elastic members that can vary by external force are stacked; and an output part connected to the ductile part so as to receive the rotational force, and outputting the received rotational force to the outside, wherein the plurality of elastic members have the same or different elastic force, and are selectively varied according to the magnitude of the external force applied to the output part.
