Self-propelled robot and method for distance determination in a self-propelled robot

摘要

The robot i.e. robotic vacuum cleaner (1), has a panorama camera (8) for recording images of surroundings of the robot, and a control device (7) is arranged for evaluation of images of the camera. A laser diode (10) is arranged on the robot, where the diode emits a laser beam (11) in the vicinity of the robot. The control device is arranged to receive the images of the surroundings to detect the laser beam projected onto an object i.e. wall section. The control device determines a distance between the robot and the object based on position of laser reflex (12) on the images. An independent claim is also included for a method for performing a distance measurement with a self-propelled robot.
