I'm making  the sumo bot(one remote control and one with sensors) for the science fair at my school and i was wondering could i use another microchip because it's kinda hard to find one of those before this summer.And another question show i have an on off switch on it or something else or what?and would a ps2 controller work as a remote control?and charging NiMH battery packs i dont get how to charge them I want to know how to charge them before i buy some

Could you please clarify?  It's hard to understand what you're asking.

Are you asking if you should have an on/off switch?  If so, it's up to you.  You could just plug in your power supply every time though if you want to keep it simple.

As a tethered control, you could probably hack it as such.  Google it.  As a true remote--i.e., untethered--good luck.  You might as well buy a real remote if that's what you're going for.

Get a universal charger.  They're pretty easy to use.  Or, just use standalone AAs.  You can stick them in a battery holder (available for example, at RadioShack).  Then you can stick them in an ordinary walmart charger, and put them in your battery holder when you're ready to use them.

A cerebellum microcontroller is really hard to find was the first question. I accidently spelled it wrong and I dont get your answer to the on/off switch queston and a universal charge is one that can charge AA and AAA right? The one that plugs into the wall?

Hal9000:
Yeah, the battery charger will probably plug into the wall. Like this:

If you are doing remote control, this post is pretty good, showing that you don't need a microcontroller for remote control!:

Plus, as far as autonomy with the sumo goes, this $50 robot tutorial could be of use, and uses an avr:

Good luck!

Thank you for the help and an rc robot doesnt need a microcontroller?And I making an rc sumo robot and an autonomous sumo bot but what microcontroller should i use instead of a cerebellum one? and where can i get all the supplies for the sumo bot and why do i need 3 servos?
