(...) It's easier and heavier to do it with battery boxes. I have more then enough of those. In the MIT contest, how do they handle this? Derek (20 years ago, 1-Mar-05, to lugnet.org.ca.rtltoronto)

(...) I don't know, I've been trying to find the MIT contest webpages but I haven't been able to turn them up. I think there was a size and weight restriction in the original contest. Actually, come to think of it, all I remember was Alan Alda in (...) (20 years ago, 1-Mar-05, to lugnet.org.ca.rtltoronto)

(...) Derek's got a good point - lead bricks aren't necessary - lots of battery boxes with dead batteries, or, 8466 tires. I would suggest a digital postal scale for event day, or a mechanical LEGO-built scale. Anyone UNDER the defined weight limit (...) (20 years ago, 1-Mar-05, to lugnet.org.ca.rtltoronto)

(...) Another thought is to use some external source to hold the beam still for the first 10 to 20 seconds of the contest, allowing both robots to do their stuff, and then let the beam go. That should have the effect of slowing down the super-fast, (...) (20 years ago, 1-Mar-05, to lugnet.org.ca.rtltoronto)

(...) Yeah, the center of gravity of the whole assembly is ABOVE the beam, so the whole thing is by definition unstable. Weird. I didn't quite get it either. Are we missing something? My thinking is (and I built a quick model from LEGO) that we (...) (20 years ago, 2-Mar-05, to lugnet.org.ca.rtltoronto)

(...) Well, be aware the tiltiwhatever the hell was a "live" contest. The students had to control their machines using air pumps by hand or something and they were given like four air lines into the machine from a stationary control point. Calum (20 years ago, 2-Mar-05, to lugnet.org.ca.rtltoronto)
