A mobile that can move on a horizontal plane, including a body comprising a contact area in contact with the horizontal plane, a cam movable in rotation relative to the body about a cam axis, the cam having a contact surface in contact with the horizontal plane during its rotation. According to the invention, the contact surface of the cam comprises separate first and second portions, each of the first and second portions having a different coefficient of friction, the coefficient of friction of the first portion being greater than the coefficient of friction of the second portion, the first portion being configured to roll without slipping on the horizontal plane, the second portion being configured to slip without rolling on the horizontal plane, and in that the body is configured to rotate relative to the horizontal plane about a vertical axis perpendicular to the cam axis when the first portion rolls without slipping on the horizontal plane and to rotate relative to the horizontal plane about a horizontal axis perpendicular to the cam axis and to the vertical axis when the second portion slips without rolling on the horizontal plane.
