Mobile device and control method

The invention discloses a mobile device and a control method. Therefore, a technical problem that the existing walker can not control the motion state by itself in the prior art can be solved. The mobile device comprises a body, a drive unit, a first sensor, and a processor. To be specific, the body includes a tray frame, a base plate frame, and a support frame arranged between the tray frame and the base plate frame. The drive unit includes a guiding wheel and a motor; and the motor is used for driving the guiding wheel to move, thereby driving eh mobile device to move. The first sensor that is arranged on the base plate frame and approaches one side of an accommodation space is used for detecting a moving speed of a user. The processor connected with the motor is used for setting the rotation speed of the guiding wheel by the motor according to the moving speed, detected by the first sensor, of the user. In addition, the invention also discloses a corresponding control method.
