I'll speak from 3 seasons worth of Driving experience.
1. Listen to those who try to help you! They usually know what they are talking about.
2. Dont be intimidated by asking the programming team to fix stuff in the code. Remember, as the operator, everyone works for you for about 2 min.
3. Dont have tunnel vision. If you are driving on the left side of the field, and dont notice someone on the right jumping waving their arms and screaming your name, find a new driver!
4. Listen to you coach. They dont have anything to do BUT watch the field.
5. Dont be afraid to rough it up with other robots. Sometimes the only way out of a situation is to push.
6. Nobody should ever be mad at you for breaking the robot. Remember, it is probably mostly aluminum and aluminum isnt exactly known to be commonly impact proof.
7. Use your judgement, if you dont like a situation such as driving onto someones ramp, dont be afraid to say no! Remember, its your teams robot, and it would be yours taking the hit if anything went wrong.
Good Luck, and have fun!
