Team 467 Driving while holding the ball

You could also do a power ramp (e^x) or a quadratic (x^2) or a cubic (x^3). The posibilities are really endless...

Ahh, but they all return roughly the same result The easiest way to implement an exponential curve, I believe, is by using the Taylor (or Mclaurin, in this case) expansion. In the case of e^x, the expansion is 1+x/!+(x^2)/2!+(x^3)/3!... I would not be surprised if calculators do this same thing to compute powers.

Re: Scorpion... LOL! That's what one of our team members said it looked like too! I have a feeling that is what it will be called.

Re: COG... while it did "pop" back a bit, it's actually quite stable.. there's plenty of weight in the bottom (the last weigh-in was 91 lbs), but there's still more to add, including the "skin", some more wiring, and we've already added more strength to the drive sections (all custom built, btw).

Re: ramping... we do have a ramping algorithm, that we've used successfully for the past couple of years, but I'll let our programmers comment on that. You can see last years (Rack & Roll) robot in the background too.

Here's another one:

These are all in low gear, by the way.

Have you drive it on carpet yet?
