hmm.

I'm thinking of using a combination of all three options. First have the bot find detect the IR signal, and head to it till it gets about 3/4 there. This would be for speed; then turn off the IR detection; by then the robot should be on the white lines, then use those to get to the object. Afterwards, once the ball knocked out, have the bot turn around and head for the balls.

This way you get speed of the heading straight with IR mode, as well as the precision of line walking.

atleat I'll try that ;-). Sounds like fun.
