Abstract
A robot including at least one joint shaft that includes: a first link member and a second link member that are coupled about a rotation axis; a reducer that has an input shaft part fixed to the first link member and an output shaft part fixed to the second link member; a motor that generates a driving force to be input to the reducer; and an input-side encoder that detects a rotation angle of a rotation shaft of the motor; and an output-side encoder that detects a rotation angle between the first link member and the second link member. The output-side encoder includes a scale member that has a pattern and a sensor that detects the pattern on the scale member. The scale member is fixed to an attachment surface, and the sensor is attached to a fixing member fixed to the first link member.
