R492_e05a R492_e24a
This bot looked so much like ours that many people didn't know the difference. Both collected balls and delivered them by tilting the basket over the goal. Both lined their basket with rope.

824 Roosevelt HS, WA push, tether, low ball gather R824_e15a
833 Hawaii Prep Academy, HI push-pull
R833_c03 R833_d00
The picture at right is special because it shows 833 in a fight with our robot, 997. Sorry, I don't know who was winning. But I understand that we typically were able to push them around. On the other hand they were fast enough that they could get between us and the goal and so block us from dumping balls into it.

R997_b22 R997_c12 R997_c14
Our bot was generally fast at collecting balls. And at precisely 130 lbs it was able to push smaller bots around. It was a very strong contender and after the first two rounds was in the #1 rank. However after that we had an amazing string of bad luck and we lost all further matches. In most cases our alliance partners bots failed, and this happened with partners who were basically very strong entries.
998 Soldotna HS, AK gumball catcher R998_c12
M1 Mystery Bot If you know who's bot this is, please send me email saying who M1 is.
M1_a06a
Here you can see the use of a "tether" to locate the bot in two zones at once. We considered implementing a tether, but the postings from the first officials said that if a tether had the possibility for entanglement then it would disqualify the bot. When we got to the event we saw plenty of bots that were capable of entanglement. But the judges were not using that standard. Instead they only disqualified a bot if it actually entangled a competitor. The experienced teams may have suspected the judges would pull this switcheroo. As a rookie in a state with no experienced teams we didn't even have access to a mentor who knew the history of the judges interpretations of the rules. So it goes.
M3 Mystery Bot If you know who's bot this is, please send me email saying who M3 is. M3_d19
M5 Mystery Bot If you know who's bot this is, please send me email saying who M5 is. M5_e20a
