If my 'bot 'knew' it was getting hit from behind, it would have known to • go
forward, or forward/turn, in order to 'get away' from the offending • 'bumper'.

Even if you progammed random stimulus, there would still be a chance for • my
'bot' to go backwards, right into the 'jaws' of my opponent.  If it were • me,
random movements *away* from the direction of the bump is the best • alternative.
And to do so, you need to know from which direction the bump came.

Anyway, collection vs. debate--this is swinging more towards debate :)

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)
