Have your bot learn rotations. Have your bot follow the curves along the wire. And have it at least follow it in its general shape.
What I changed
1. Change all program to rotations.
2. Make the program go farther for the straight aways and set them both by 10.
3. Change both turns by taking away one rotation.
What I Learned
It is very had to follow a wire exactly especially when it moves if you or other bots run in to it. But making the general shape is a little easier. It takes a while to find exact measurements by guessing so the best way is looking at the course and figure out rotations to distance.
