News editors obtained the following quote from the background information suppli ed by the inventors: “BACKGROUND ART “In recent years, in robot arms for industrial use and the like, it is desired t o reduce the size of a device so that the device can be used even in a restricte d working space, and in particular, to reduce the size of a joint unit. “Patent Literature 1 discloses a hollow driving module that includes a hollow mo tor, a decelerator, a torque transmission unit, and the like, and is usable for a joint of an industrial robot.” As a supplement to the background information on this patent, NewsRx corresponde nts also obtained the inventors' summary information for this patent: “Technical Problem “Incidentally, in this type of joint unit, an angle detection mechanism that det ects a rotation angle may be provided on an input/output shaft, or an input-side or an output-side of the decelerator to perform a desired control and grasp a s tate. For example, the hollow driving module disclosed in Patent Literature 1 is provided with a first encoder that detects a rotation angle of the hollow motor, and a second encoder that detects a rotation angle of an output side of the de celerator.
