Title: OBSTACLE DETECTION SENSOR FOR ROBOT
Abstract:
An obstacle detection sensor for a robot. The robot is provided with at least one linear laser emitting device (1) facing the ground in front of the robot; at least one digital imaging module (2) is provided in the front of the robot at a position lower or higher than the linear laser emitting device (1); the digital imaging module (2) is mainly used for feeding projection lines of linear laser rays at a projection position in front of the robot into a CCD or CMOS photosensitive elements of the imaging module (2); whether the projection lines of the laser rays on the ground are blocked by obstacles can be determined according to positions and shapes of the laser rays on the photosensitive elements; the linear laser emitting device (1) is a plurality of "一"-shaped linear laser emitters (11) that have small field angles and are arranged side by side on the same plane. The plurality of "一"-shaped linear laser emitters (11) can extend a "一"-shaped line before leaving a robot body, so as to have a larger coverage range than a single "一"-shaped linear laser emitter.
