Combat RC / ESC/BEC controllers and motors- Brushed and Brushless

Hey LMR I was hoping you could help me with a few questions the internet/google cannot fully teach me haha.

So I am thinking about maybe making a combat robot/battle bot (http://www.robotmarketplace.com/therobots.html) whatever you want to call it with some left over cash. So I have some questions on Brushless and Brushed motors.

What is the difference between Brushed and Brushless? So far I understand that one has three wires and the other two- +, - , brushless has a servo wire( to make it simple for me ;)    So what am I missing? Is one geared or what?

Future ideas- robots and paintball

-http://letsmakerobots.com/node/25679 (ill try to get my robot post on that one going, almost done :] )

So Im sorta running out of ideas that are worth using and cheap enough. 

For example-http://letsmakerobots.com/node/23474 i learned it was a little too expensive for me - a kid- to make and experiment.

Microphone programming on picaxe

Summer is here and I am trying to do as much programming with my robot as possible... so....

Ok I was looking for a forum or something on programming a microphone for picaxe so I can play it back on my speaker but found nothing. If anyone knows of a forum that has done this already please tell me! 

Ohterwise I want to hook up a microphone witch i believe i know how to do- http://www.rev-ed.co.uk/docs/picaxe_sound.pdf

but I do not know how to program it at all. So if anyone has more knowledge than me(which is a good possibility) then please tell me. 

Sharp programing on picaxe

Ok so I want a basic obstacle avoiding program with my sharp sensor. It is made on the start here robot. The programming language is picaxe basic. After hours of trying I still cant get it going correctly. So i hope u can help me. Thanks

The idea- It is supposed to read the distance and then decide whether it is far enough away to proceed forward or to go to sub program ahead (go backword, I know confusing haha sorry). So if you have any ideas please tell me. Better yet revise my program or make a new one and show me it. Thanks! First time with sharp.

Paintball gun wieght- approx.- 4 lbs

Remote Controlled combat robot

Hello everyone and thanks for the help. I would like to know what kind of motors I would need for a rc vehicle to move around 5-10 pounds at max, If you could tell me how this torque thing and rpm applies to wieght and pulling ability I would extremely appreciate it. Also it needs to be able to handle tough terrains- mud, hills, debri, etc. - An outdoor fighter.

It will have a paintball or airsoft gun mounted on it and that i am thinking will be moved up and down by a servo and shot (the trigger pulled) by a servo also. 

Gives other players, soldiers, a new perspective.
