There is the classic Polaroid ultrasonic range finder. I think someone here was working on one of these or similar for lego? They work on the reflected signal approach. Now I thought you wanted to do off board triangulation. You can accomplish that (...) (25 years ago, 30-Nov-99, to lugnet.robotics)

Subject says it all... Whether you have a Hannukah bush, a Kwanzaa shrub, or a Christmas tree, it's your DUTY, if you have any trains at all, to get them running around the tree. This will be year #3 for me. Good clean fun. (25 years ago, 30-Nov-99, to lugnet.fun.holiday)

My pieces seem to be getting jumbled and make half the time spent building, looking for that piece I know is somewhere. You guys have any good ideas for neatly storing a set that includes * RIS 1.0 * 1.5 upgrade kit * robo sports set * extra motor (25 years ago, 30-Nov-99, to lugnet.robotics)

|

Thinking about the door frame from 6195 made me think again about a part variation I noted the other day while I was sorting out 20 copies of 6444 Outback Airstrip. While sorting, I always put together all the pieces of any windows and doors. 6444 (...) (25 years ago, 30-Nov-99, to lugnet.general)

Like Pete said, this won't work. When people use lasers (or sonar) to measure distance, they reflect the signal back to the source and use phase shift to make the measurement. The proposed scheme would have to compare arrival times between the (...) (25 years ago, 30-Nov-99, to lugnet.robotics)
