first robot

were do i start in building my first robot. what do i need to know?
thanks in advance

You need to tell us what you know already, and what you want your robot to do.

Also, probably best not to change topic mid-thread.
Topic split.

thanks for the advice.

well i know the stepper wont work,this is stepping above what i have done with arduino. arrays is all i have worked with. what my plans are is to make a land rover of sorts that gos back forwards turns in a dime maybe even carry sensors cameras ext.

thanks in advance
