Title:
ANGLE CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/246521
Kind Code:
A1
Abstract:
In the present invention, a robot comprises an actuator that, according to a command value, changes the angle of a second member with respect to a first member. In a first step of this angle calibration method, an inter-parts-to-be-measured distance, which is the distance between two parts to be measured, one of which is disposed on the first member and the other of which is disposed on the second member, is obtained by measuring the distance between wall surfaces of the parts to be measured while a discretionary command value is given to the actuator. In a second step, on the basis of a reference inter-parts-to-be-measured distance and the inter-parts-to-be-measured distance obtained in the first step, the reference inter-parts-to-be-measured distance being obtained previously by measuring the distance between the parts to be measured while a discretionary command value is given to the actuator, the angle difference that corresponds to the difference in the two inter-parts-to-be-measured distances is calculated.
