I've actually decided to change my first robot.I am not going to make a lightseeking robot after all .i am still not sure what i'm going to do wit my robot,but i know i will be using some wood as my base and my base will be a T-shape. I will be using two 3 volt motors for my drive mechanism. Maybe I'll have a robot that uses touch sensors to find it's way around. I still don't know,but I'l have lots of time to figure it ot over summer vacation.
