This is not ideal.

As a first whack, OK (despite the very big lack of safety), but now at least get a big fuse or circuit breaker in there.

Very much preferred at this stage - a week in - is to have the RoboRIO controlling it through a motor controller. This way you can:
1. Adjust the speed very finely so accuracy is spot-on
2. Use a speed sensor on the motor or wheel to (try to) keep the wheel speed constant, so ball #12 goes to the same spot as ball #1.
3. Get a better idea of what you will see in reality when the robot is actually doing the controlling (The motor controller doesn't give as much voltage to the motor as a direct connection might).

All of these point more towards success. Yes they require effort, but do you want to win or watch?
