(...) I found a yellow LEGO rubber band on the TECHNIC table, so I took it home with me since most everyone was gone by that point. That's probably not a big deal, unlike an entire train regulator. :( (19 years ago, 6-Sep-06, to lugnet.robotics)

(...) Well, sort of. First, what the US sensor returns is the range of the nearest sound-reflecting surface: but it's not a pencil thin laser beam of sound, so the same object might be detected at slightly different angles, making the object apeear (...) (19 years ago, 6-Sep-06, to lugnet.robotics)

(...) Actually, my counter was mechanical, in that each ball temporarily opened a normally closed touch sensor, and the RCX was just counting touches. For an optical one, you can use a ball breaking a lightbeam (two light sensors pointed at each (...) (19 years ago, 6-Sep-06, to lugnet.robotics)
