Is this actually true? John? Other 148 members? That seems like something even 148 wouldn't attempt.


Our drive this year was geared for 18.5 ft/s in high gear after accounting for losses. Before losses, the theoretical free speed was something like 22+ft/s.

I discussed this in another thread, but controlling the robot at that high rate of speed is not something to take lightly. Here is the other thread- Post #s 8, 10 and 12 were my comments on driving at that speed: http://www.chiefdelphi.com/forums/sh...42#post1085342

Some teams routinely can handle the high speed, but it is certainly not for everyone. My main point is don't assume you can drive that quickly and be able to just control it like you could a slower robot. Make sure you have good reasons to go for it, you've done the math, have a solid design and a good strategy for control and you will be ok.
