The sensor uses a red visible point laser, so it is very suitable for some maze mapping tasks, for example, because it is not blocked by nearby objects like other distance sensors with a large field of view. The range is from 1 cm to about 10 m depending on the conditions (external lighting, target reflectivity\u2026). In this case, a small LEGO EV3 motor is used to rotate the compact mirror, so the entire 360\u00b0 area can be scanned. An additional optical sensor is used to reference the mirror position.<\/p>\n\n\n\n<p>Thanks to this project, we were able to test several new features implemented in Open-Cube &#8211; I2C communication between multiple O-Cs, wireless code upload in micropython, and more.<br>Authors: V\u00e1clav Poustka and David Steinmann, 2nd year of bachelor studies, Cybernetics and Robotics, Faculty of Electrical Engineering, Czech Technical University in Prague<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"982\" src=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot1-1024x982.jpg\" alt=\"\" class=\"wp-image-1236\" srcset=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot1-1024x982.jpg 1024w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot1-300x288.jpg 300w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot1-768x737.jpg 768w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot1.jpg 1081w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"749\" height=\"927\" src=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot2.jpg\" alt=\"\" class=\"wp-image-1237\" srcset=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot2.jpg 749w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/robot2-242x300.jpg 242w\" sizes=\"(max-width: 749px) 100vw, 749px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"548\" src=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-1024x548.jpg\" alt=\"\" class=\"wp-image-1241\" srcset=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-1024x548.jpg 1024w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-300x161.jpg 300w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-768x411.jpg 768w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-1536x822.jpg 1536w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/pcSW1-2048x1096.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">PC application for LIDAR data visualization and robot control<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"736\" src=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/rangefinder-1024x736.jpg\" alt=\"\" class=\"wp-image-1238\" srcset=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/rangefinder-1024x736.jpg 1024w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/rangefinder-300x216.jpg 300w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/rangefinder-768x552.jpg 768w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/rangefinder.jpg 1253w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">O-C Laser sensor<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"565\" height=\"301\" src=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/module1.jpg\" alt=\"\" class=\"wp-image-1239\" srcset=\"https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/module1.jpg 565w, https:\/\/open-cube.fel.cvut.cz\/wp-content\/uploads\/2025\/06\/module1-300x160.jpg 300w\" sizes=\"(max-width: 565px) 100vw, 565px\" \/><figcaption class=\"wp-element-caption\">U85B laser rangefinder module<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>A nice project to test the newly available Open-Cube sensor &#8211; a laser rangefinder based on the &#8220;U85B&#8221; module extracted from the commercial handheld Asist LM030.
