you do with a laser? Is it used for guiding the robot or can the RCX detect

| I've found that shooting a laser pointer at a bicycle reflector gives a good enough return (to a light sensor right next to the laser source) to be detected. You can use this for navigation, as the RCX can turn around and find strategically mounted (...) (25 years ago, 14-Nov-99, to lugnet.robotics)
