Document Type and Number:
Japanese Patent JP2019063894
Kind Code:
A
Abstract:
To provide a robot that miniaturizes an optical signal transmission device and can control intensity of light emitted from a light-emission part, and to provide a printer, a projector and an optical signal transmission device.SOLUTION: A robot includes: a light-emission part; a light guide part including an optical transmission path optically connected to the light-emission part and propagating light emitted from the light-emission part; a branch path disposed in the light guide part and branching from the optical transmission path; a light receiver for receiving light propagated through the branch path; and a control part for controlling intensity of light emitted from the light-emission part based on the intensity of light received by the light receiver.SELECTED DRAWING: Figure 5
