Help with programming...

[hemanth]

Im new to robotics and programming. I just want a code for a simple 4 wheeled bot to either go forward or turn(by letting wheels on the Left hand side spin in a direction and the other 2 in the reverse direction). can anyone generate a code for me<any board is fine, I still havent purchased 1!>

any sensors or buttons, what do you want to activate the turn.

when i know this i'll give it a shot.

$50 robot tutorial?

turn it into a 2 wheeled 1 castor robot and you can use simple diferential drive.

then take the mcu and code from the $50 robot tutorial.

I would suggest buying a programable robot kit. It would come with the board plus the code.
You will be able to more than just going forward and turning.

Only 1 switch for keeping the entire bot on or off, no sensors

what will cause the robot to turn? or you just want it to be a sequence.

will you use servos or motors?

servos...but every action is done manually(no sensing obstacles and turning, etc)

I mean what do you want to make it turn.

A different switch?(each time you hit the switch it turns 90 degrees right?)

As you just said you wanted a swith to turn the bot on and off.

This turning behavior is akin to a tank (or any tracked vehicle).
Find the Surveyor C source code from their website, it might help you understand how it's done.

My Surveyor makes its turns like you mentioned.
