Abstract: The disclosure relates to a method for monitoring a pet by a robot based on a grid map and a chip. A mutual position relationship between the pet and the robot is determined through wireless communication between a wireless signal device on the pet and the robot, and then whether there is an obstacle cell or not between grid cells where the robot and the pet are located in the grid map is judged. If NO, it is indicated that the pet may be effectively shot at a present position and shooting direction of the robot, and the present position and shooting direction of the robot are not required to be changed. If YES, it is indicated that no pet but an obstacle may be shot at the present position of the robot.
