What sensor should i use for my robot? Answered
Right now my robot has a twin motor tamiya gearbox and 2 wheels in back and a servo with 2 wheels hot glued to it in front for steering and an arduino duomilanove for the brain and it works pretty good except there are no sensors so its not really a robot at all! What I want to do now is buy a sensor that will be able to make my robot avoid obstacles and my track my hand or something. I have ben looking at some sonar sensors, ping sensors, and those sharp ir sensors but i don't know what to pick. It would be great if someone could help me out also I am just getting started so something not tooooo hard to use i mean im up to the challenge though.
