Thanks agian for the knowledge folks

Here is our updated plan. Lets see if we understood the feedback correctly.

Re: Will this circuit work?
 

If the devices you are using are in compliance with <R92>, you should be all set. That being said, I'm not sure that they are...

Re: Will this circuit work?
 

That looks good to me.

Switch one is normally open

Switch two is normally closed

I think that will work well. Motors in Parallel??? I mean sure why not harder to physically wire but sure...for this application series will be work just fine

Re: Will this circuit work?
 

That's not correct at all. Motors in series would get approximately half the voltage and spin half as fast. In a Minibot race you really don't want to do that (for the way up at least).

Re: Will this circuit work?
 

Yes the voltage drop across them would be cut in half.....Yes right DUH.....Sometimes I loss my head

If the "shunt fields" are just coils that they manufacture out of the allowed wire, then they should be fine, if they are anything more than that, they might have trouble. That being said, the "shunt fields" aren't really necessary, the minibot should do just fine if it is simply turned off. if this makes it fall too slow, I suggest a loop of lexan for a bumper.

JJ,
If switch number one is normally opened until you contact the tower and switch number two is normally closed until you reach the top, then this configuration should work. What remains is how to get the minibot down.
For those lurking here, the motors don't contain shunt field coils since these are permanent magnet motors. This is just a drawing.
