Re: FASTEST 2008 ROBOT

I will be seeing them this weekend, so I will make sure to ask, but I wouldn't be surprised to see 930 in the 25 range. I know Wobot 141 was 22 in high gear if I remember correctly.

Re: FASTEST 2008 ROBOT

what about 1024 and 1114? both pretty fast bots..

Suprisingly we were only about 13-15 fps. Wobot was significantly faster then us when they went into high gear. We just concentrated pretty much completely on laps. Our max laps in tele was 11(dunno what were gonna do this weekend... laps or defense depends on the rule changes i guess). This just shows you don't need to be fast to make laps

Re: FASTEST 2008 ROBOT

I think 254's bot was crazy fast... They probably could have done 6 lines in auto easily given the time...

Our team focuses on continuous improvement. We knew that bringing our St Louis game to New Orleans would be foolish. (Though, I think we all wish the auton would have been up to the STL level.)

364 has an incredible machine, and they are a great team. I'm looking forward to seeing them again at IRI. It was cool to see such a great hurdler could also function well as a lap-bot.

This is true. We are geared at about 20 ft/s free-speed. During the build season we were geared as high as 30 ft/s free-speed, but this turned out to be foolish.

Our goal was to build a robot which was fast on the field, not fast in a drag race. Our experimentation and iteration showed that we were faster and more consistent with a slower top-speed (it is weird to describe 20fps as "slower").

This is why we would get beat easily by some other lap-bots in drag-races, or in open-field lap-races. However, this system was not intended for either of those scenarios, ours was designed to compete in a FIRST Overdrive match, with 5 other robots. *shrug*

We may be one of the fastest robots, but we are not the fastest.
Kudos to all the teams who can toast us!

I definitely noticed 148's transition to a defensive bot, especially at the championship. I congratulate your team's success. I believe I watched one of the videos with your team geared to 30FPS. When Tumbleweed went around a corner, it tipped on its side (can't really say one or two wheels). I would hate to keep control of the robot going at that speed.

Our robot is geared right around 15FPS, with 6WD and 4 CIMS. We could have been much faster if we had wished, but we ended up going with a mid-speed robot with a lot of power. In autonomous we had to ramp up our start because we would make a wheelie. I believe our robot is fast enough and strong to be competitive. I only really wish our hurdling ability was a little better, but we were worried about our COG with more mechanisms toward the top of the robot.

Re: FASTEST 2008 ROBOT

Team WOBOT had a pretty fast robot too. about 21 fps. It was only about 16 fps at the Wisconsin and West Michigan Regionals, but we bumped it up by fixing some glitches in the code to 21.

Re: FASTEST 2008 ROBOT

102...they are qwicked fast. I believe 27 feet persecond correct me if I'm worng.

Re: FASTEST 2008 ROBOT

i believe we maxed out at 11 laps at Bayou(according to Bomb Sqaud) with Bob only going 15ft/s.

we also saw 148 in Bayou, we just had no idea you guys were playing the defensive role.

u were known for the laps in St. Luis so when we saw you guys we were confused.

I can confirm this.

102 was the fastest robot in FRC this year. They were not the quickest to accelerate, but their top speed was faster than anyone else I saw*.

Team 102 won the FIRST Finale Asphalt Challenge by covering a 110 ft. course in 4.45 seconds. This AVERAGES out to almost 25 feet per second. Their top speed was above 28 fps, I would assume. Other "fast" robots ran this course at no faster than 5.5 seconds.

On the Overdrive field, 102 was able to get good speed in the straightaways, but they were slower at accelerating compared to a few other robots.

Re: FASTEST 2008 ROBOT

Eagle Corps Robotics (Team 1158) pulled 10 laps at the San Diego Regional and averaged over 8 laps per match at the Colorado Regional.

Re: FASTEST 2008 ROBOT

Hay Andy, what gear boxes was 102 using? :)

16 laps? really? can you post a link to that match?

I also thought 1114 was pretty fast, but they assured me it was only geared around 15 f/s.

If I had to choose my favorite 'fast bot' it would definitely be Cheesy Poofs. I just loved their robot and their techniques on how to not only have a fast drive, but fast slide, etc.
