The present invention relates to the positioning control technology field of a robot device, in particular to a mobile control device and a mobile control method. The mobile control device comprises an acquisition unit used for obtaining the point cloud data of a robot in a current environment and forming the acquisition data to output according to the point cloud data; a control unit used for receiving the acquisition data and forming a control signal to output according to the acquisition data; and a mobile mechanism for driving the robot to execute the corresponding movement under the action of the control signal. Compared with the prior art, the advantages of the present invention are that: the acquisition unit real-timely acquires the distance information between the robot and the obstacles in the current environment to determine the position of the robot, so that a plurality of emitters do not need to be arranged, and the cost is lower; a range finding mode changes from receiving the signals emitted by the emitters passively to sending out the range finding information actively, so that the resource utilization rate is improved; at the same time, the acquisition devices acquire, the range finding information is accurate, the positioning accuracy is high according to the more accurate range finding information, and the efficiency is higher.
