Abstract:
A robot includes a base, a robot arm provided to be turnable around a turning axis with respect to the base, and an encoder including a mark configured to turn around the turning axis according to the turning of the robot arm and an imaging element configured to image the mark, the encoder detecting a state of the turning of the robot arm using a signal output from the imaging element. The encoder includes a telecentric optical system disposed between the imaging element and the mark.
