1. A robot comprising:
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 arm base is rectangular-shaped in a plan view, and the arm base has first and second side surfaces opposite to each other and third and fourth side surfaces opposite to each other,
each of the first and second side surfaces is longer than each of third and fourth side surfaces,
the cover includes:
a cover main body that covers an entirety of an upper portion of the arm base; and
a covering section that protrudes downward from the cover main body and that covers the third side surface and a portion of the first side surface of the arm base,
wherein an outer surface of the covering section is defined as a first surface and part of the first side surface not covered by the covering section is defined as a second surface, and
wherein at least one of:
an wavelength of reflection light on the first surface and an wavelength of reflection light on the second surface are different; or
an intensity of the reflection light on the first surface and an intensity of the reflection light on the second surface are different,
another part of the first side surface covered by the covering section, and
a first distance between the third side surface and the first surface of the covering section, which directly faces the third side surface, is larger than a second distance between the another part of the first side surface and the first surface of the covering section, which directly faces the another part of the first side surface.
