Heh, I ripped the front end off as well. Other than that, I did the
exact same mods. Wow. :-)

I've got the sonar going - it's neat for looks, but I'm still
working on putting enough code behind it to make it fast and functional -
servos are SLOW! (Ping, move, THWACK, ping, object 1 cm away... ;-) How
are you going to get all those IR sensors on? How will you interface them
to the HB? Once thing I've noticed is that the timer lines get used up
really quickly... :-( I'm out! I stuck two microswitches on the front of
my bot, but I'm disappointed with their performance - they keep falling off!
I can seem to find a good way to attach them... I also need to work on the
"arm" they use to sense objects, it twists and breaks easily.
Ok, it's time for a complaint against the CAT D10. It doesn't turn
well when it's heavy, on carpet. I've mounted a sub C nicad pack, the HB,
sonar, etc on my bot, and now it's almost to heavy to be able to pivot
itself. I tell it to turn, the treads slip on the driving wheel thingies,
make a bunch of bad noises sometimes, and then it finally manages to throw
itself around. Bad. I really wish it would perform better turning,
because it does just fine going in a straight line! :-)
