If you make it to the wall in less than 3 seconds my hats off to you!
If you draw out the line your bot follows from starting position, to the boxes, and calculate the max possible acceleration, including the turn, then you are pushing the laws of physics to get there in less than 3 seconds.
Im not saying it cant be done ( didnt you see the :c) in my post?)
if you are getting there really fast you must have sacrificed something, accuracy, weight (how heavy is your bot?), number of boxes you can hit...
Getting to the wall first is not the whole story - you want to take out 3 or 4 columns, push ALL the boxes into your scoring zone, do it consistantly
and still have a bot that is able to push other bots around, hold its own on top of the ramp...
I wouldnt be too sure about a 180 turn being faster than a V turn. either way your bot starts out heading south, and it has to accelerate to head north - whether its by a sweeping 180 turn, or a back and forth V turn - you are still converting all the momentum of your bot from one direction to the opposite direction.
Gettting their first makes a big difference:
1. you hit the boxes first, you send them flying in the direction you choose - sometimes over the top of the slower robot coming up the other side
2. you have more momentum when you hit the slower bot
3. you are on your way DOWN when you hit the slower bot - gravity is on your side
4. your bot is more stable hitting another on the way down, then being hit on the way up - less likely to be tipped over backwards.
Our general strat at the Canadian regional was to let our auton mode hit the wall fast (we got it down to about 4 seconds) - our flying squirrel spanned 5.5 feet and always took out at least 3 columns - the bot stopped in the scoring zone so the boxes were all 'keepers'
and then we pretty much stayed on our side of the ramp to get as many boxes in the zone, protect our stack, build a stack if we needed to
then hit the ramp at the end.
We were doing very well with this strat in Canada. We were ranked 8th in our second last seeding match, and were averaging 140 points (winning most of the time).
We lost our last match and dropped to 16th, but we were picked in the first draft by the 5th ranked team.
