Hi,
I finally found the time to put a web page up for the bots i built two years
ago:
http://www.lowpoly.com/lego/index.htm
First bot is a lego only vacuum cleaner bot on a 3 x 2 wheeled synchro drive
chassis.
The vaccum worked, the synchro drive only until errors accumulated, which
was soon, unfortunately.
Second bot is a chassis for a lawn mower, also with 3 two-wheeled platforms
but this time they are spring suspended. Just as a size ratio, this one uses
the wheels from the last super car.
Many pics, the page may take some time to load.
Stefan
PS: I remember I need a disclaimer concerning LEGO? Where would I find that?

| Thanks everyone for the comments. Iain: I know the offset solutions. Two wheeled seemed to be a lot more stable back then. Rob: Good stuff on your page. Do you thing BrickOS will read the rotation sensor faster? That might solve everything. BTW, I (...) (22 years ago, 10-Jan-03, to lugnet.robotics)
