This year we got this award at Dallas Regional. A very rewarding thing for a 3rd year team (which dramatically sucked during its first 2 years).
Our robot had nothing too special however we used a dual elevator system which i have not seen at any other team. Many teams snaked their treads or wires to pull all the elevator to all the way up but our elevator was actually made out of 2 seperate elevators. If one of them fails the other can take over and score and often the positioning was better than most snaked elevators.
We used 6 inc mecanum wheels with shaft drive. Our autonomous worked 50% of the time but we did not ram into any one.
Nonetheless we did not use any sensors to track our movement in the autonomous but we used timed movements. (hours of practice needed and still room to improve.)
Our elevator was using a very simple servo to hold the tube with a finger at its tip. This finger started at 0 degrees at the beginning and when robot reached the racks servo moved to 90 degrees to drop the tube to the rack in front of us.
I would love to thank that post available on Chief Delphi that taught this LabView rookie how to use timers and loops in a more effective way though.
