A robot includes a multi-articular arm and a base including a body. The body has a first supported surface and a second supported surface opposite to the first supported surface. A first bracket and a second bracket are connectable to the first supported surface or to the second supported surface to connect the body to the floor surface or the wall surface. Each of the body, the first bracket, and the second bracket has a mounting member such that the base is mounted on the floor surface when the first bracket is connected to the first supported surface and the second bracket is connected to the second supported surface, and such that the base is mounted on the wall surface when the first bracket is connected to the second supported surface and the second bracket is connected to the first supported surface.
