Robot

Abstract

A robot includes a base; a first arm rotatably connected to the base around a first rotation axis; and a second arm rotatably connected to the first arm around a second rotation axis parallel to the first rotation axis, wherein the second arm includes an arm base and a cover configured to attach to and detach from the arm base, the cover includes a cover main body that covers an upper portion of the arm base and a covering section that protrudes downward from the cover main body and that covers a portion of a side surface of the arm base, and when an outer surface of the covering section is defined as a first surface and a side surface not covered by the covering section among side surfaces of the arm base is defined as a second surface, at least one of wavelength of reflection light on the first surface and wavelength of reflection light on the second surface are different, or intensity of reflection light on the first surface and intensity of reflection light on the second surface are different.
