Title:
ARTICULATION UNIT, ROBOT ARM, AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2019/198525
Kind Code:
A1
Abstract:
[Problem] To provide an articulation unit that is small yet provided with a plurality of angle detection mechanisms. [Solution] Provided is an articulation unit comprising: an input-side support member for supporting an input shaft that is rotationally driven; a reduction drive for reducing the speed of the input shaft and providing a deceleration output shaft; an output rotating body that is coupled to the deceleration output shaft and that includes a strain part where strain is caused by rotation transmitted to the deceleration output shaft; and an associated rotating body that is coupled to a later stage portion of the strain part of the output rotating body, that rotates together with the output rotating body, and that is arranged in a space between the input-side support member and an earlier stage portion of the strain part of the output rotating body. In the articulation unit: a first angle detection mechanism for detecting the angle formed by the associated rotating body and the input-side support member is provided to the associated rotating body and the input-side support member; and a second angle detection mechanism for detecting the angle formed by the associated rotating body and the earlier stage portion is provided to the associated rotating body and the earlier stage portion of the strain part of the output rotating body.
