Mobile robot and safety control system thereof

The invention relates to the technical field of safety control of mobile robots, and discloses a mobile robot and a safety control system thereof, and the safety control system comprises a first monitoring circuit which monitors the movement data of the mobile robot; the second monitoring circuit monitors whether the mobile robot collides with an obstacle or not; a third monitoring circuit monitors whether an obstacle exists in a preset range of the mobile robot or not; the safety control circuit generates a first safety instruction based on the mobile data, generates a second safety instruction based on the collision signal, generates a third safety instruction based on the warning signal, and generates a fourth safety instruction based on the state information of the safety input device. The servo circuit receives and executes the corresponding safety instruction; and the main control board outputs a driving control signal to the servo circuit, so that the servo circuit controls a motor of the mobile robot
