Even with the 46.4% chance that there will be a 2 or 7 vision tetra, it is *extremely* hard to get a robot to drive straight, even with encoders and gyros, for 27 (actually about 20+) feet.
You do the math, if your 9" diameter wheels are off by 0.1 inches, how much horizontal difference will there be between the left and right sides after 20 feet of matching wheel rotations? What position will your robot be in when it drives through the positions 2 and 7 and what will the orientation be when you arrive at the center? What tolerance do you have to actually get the tetra on the goal in a scoring (meaning you can't be touching it) position?
And can you do it all in 15 seconds?!?!?!?
Contrary to Team 25 (offering the Tiki trophy), we *know* it *can* be done, but a bunch of semi-controllable variable have to align *after* the 46.4% has been achieved!
