There is one solution for staying 100% Lego and putting 4 sensors on the
same RCX input. Therefor you should be able to sense which direction you
were getting bumped. Lego made Cybermasters in Europe a couple of years ao.
This was a pBrick like the RCX. The interesting thing was it had 3 touch
sensors in it, each of which had a different resistance value. If you used
1 each of these in parallel with one from the RIS kit, you could read one of
4 different values in raw mode.

| (...) Oh I wish I had some of those touch sensors! One person from rtlToronto has a set and there is much envy from me to him. Right now I'm using lamp bricks, which isn't that great, really, but does work :) Thanks for the heads-up! Dave K (...) (21 years ago, 3-Dec-03, to lugnet.robotics)
