 When we got it tuned to the point where we were (reasonably) confident it wouldn't slam into Dave's ankle, we quit for the evening. - Kevin Watson [more] |

Re: 6WD vs 8WD
Gearing was never mentioned, now was it? I'm sure it's possible for a 90-lb robot to be geared to move at 50 fps. How long it takes to get up there, though, might take longer than the length of the field.
Chris, the implication was that traction limiting happens at that acceleration for a 90-lb robot, not that the robot was geared high. It's extremely rare to see a robot geared that high, or traveling that fast, but it could happen. Some of the lapbots from 2008 had pretty fast speeds and good drag-racing potential, IIRC, though the field in 2 seconds is pretty fast for an FRC robot. Being traction limited may give a higher maximum top speed than gearing allows. However, top speed is always limited by gearing. |
