A robot includes a main body, a handlebar disposed on the main body and grippable by a user, a detection unit that detects a load applied to the handlebar, a moving device including a rotating body and moving the robot by controlling the rotation of the rotating body, and a switching unit that switches a support mode for supporting the user with walking. The support mode includes a first mode in which the robot autonomously moves to guide the user who is walking and a second mode in which the robot moves in accordance with a first load detected by the detection unit. When the robot moves in the first mode, the switching unit switches the support mode from the first mode to the second mode on the basis of the second load detected by the detection unit.
