Hello,
I have been looking for info on how to build a posi-trac differential, which
supplies power to the wheel with the /most/ resistance instead of the least
as with a regular differential. I was hoping the functionality was
mechanical, but I am starting to guess it is computer based. Any hints?
BTW, this is all due to the steerable shrimp I have been aiming towards
since I first saw Mr. Ferrari's page.. I had a lot of brick bay shopping to
do before I got to where I could build it, as well as waiting for my (first)
RCX to show up. Now I am in he middle of the move with the shrimp skeleton
in one city and the RCX in another, oh cruel fate...

At any rate I had started with a similar design but have since been
influenced a lot by this design:

I am highly inspired to get this move over!
