Im new at robotics and need HELP.

(1/2) > >>

itln:
I have built 2 robots from kits and want to start building from scratch. But I have almost no knowledge on what parts do and how much they cost and I hate to have to do all that research. I want to talk to a real person and not just a book or web page.

itln:
I know I need to do research. But I've bought 2 books and am getting nowhere. I just wish there was a free online scource that told you everything. I read plenty of sites but I never really grasp any of it. Also another factor is cash. I have read dozens of sites that say Im going to need hundreds of dollars (normally 100 to 200) and I am really tight for money lately. I can buy mabye a third of the stuff they want me to and then what do I have. Half of a robot that can roll down a hill but I have to push it first.

a friend of mine built this as his first bot:

with the sort of money you are looking at it would be a good option.
the most expensive components would be the motors.
you have to but the guy's book for instrucions but it's suposed to be a good book.

That does not look that bad but I've done a line following robot before. I'm looking to make a cheap robot then put in a microcontroler I got for free. Problem is I don't know how, where, and what I have to hook it up to. I'm afraid that even though I got a microcontroler I am going to have to buy crap loads of special parts or sensors. Kinda lacking on money.
P.S cant find any 6v MiNh batteries for this project.

dunk:
what kind of microcontroller do you have?
some require expensive programmers and some don't.

as for sensors, start simple. bump sensors can be made from any push switch.
