Abstract

See full text

a speed reducer angular transmission error identification system including a variation data acquisition unit that acquires first variation data indicating a periodic variation of an operation of a second joint caused by a first motor's angular transmission error when a first joint control unit rotates a first motor's output shaft in a first direction at a constant first target speed and a second joint drive unit rotates an output shaft of a second motor at a constant second target speed, second variation which is data indicating a periodic variation of an operation of second joint caused by the first motor's angular transmission error when the first joint control unit rotates the first motor's output shaft in a second direction at the constant first target speed and the second joint control unit rotates the second motor's output shaft at the constant second target speed.
