[HELP] Building fastest line follower

Hello guys…
I’m planning to build fastest line follower. I want the right components for it. I have previously built a line follower using Arduiono uno, L293D, 150rpm motor, and 5 IR sensor. The IR sensor which I built isn’t that reponsive and it has created hell lot of problems to me.

So, in building fastest line follower, guide me in choosing the right componets for it. Is arduino uno (Atmega328) sufficient for my project?
I’m planning to go with Pololu’s 30:1 Micro Metal Gearmotor HP (any suggestion on that?). For controlling the motors I mentioned, is L293D enough? And What about IR sensors?

Thanks in advance.

I’d be happy to answer any questions you have about our products, but we can’t choose all your components for you. However I do recommend replacing the Arduino UNO, the L293D, and any clamp diodes with a single Baby Orangutan B-328.
