(...) I've made one. A wall follower. I set the sensor to raw mode and looked at three ranges. It tried to stay in the middle range, which for this 'bot meant lightly touching the wall. The wall follower had a bumper analogous to a highly curved (...) (22 years ago, 12-Sep-03, to lugnet.robotics.rcx)
