Abstract
A method for controlling a laser pointer projection of a pet companion robot device to interact with a pet includes the steps of: determining a focal length 1 of the camera; determining a height difference Δy between the at least one laser pointer steering motors of the laser pointer and the camera; determining a horizontal viewing angle α of the camera, a corresponding horizontal viewing range is (−α/2, α/2); determining a vertical viewing angle β of the camera, a corresponding vertical viewing range is (−β/2, β/2); determining whether the touch screen of the wireless remote-control device is touched; when the touch screen of the wireless remote-control device is touched, determining the corresponding coordinates (i, j); calculating an angular difference Δθ between the camera and the at least one laser pointer steering motors; and calculating a horizontal steering motor rotation angle θx; calculating a vertical steering motor rotation angle θy.
