Let's Make Robots!

linefollowing

Line follower project

Hi guys, I'm working to build a linefollower robot to compete in both linefollowing and maze solving contests, but I've a few questions and problems I hope you could help me resolve.

MOTORS:

Well, the first problem are the motors. At the beginning I was using two 3v - 6v motors and this worked fine, but I had to duplicate the H-Bridge chip on my Picaxe 28X1 Started Pack due to the high amperage they required.
