Re: What's your plan for Autonomous?

We do plan to have multiple autonomous routines, so we can adapt to our alliance.
  • The simplest is basically the same as the "mobility bonus" from last year - just drive forward a fraction of a second.
  • The main one is to build a 3-tote stack and carry it into the auto zone. We're already planning a largely automated "align/stack/lift" bottom-stacking routine for tele-op using a pair of Sharp optical range finders, a string potentiometer, the camera, and touch sensors on the lift; the algorithm should work equally well for grey and yellow totes. To score a tote stack, we just need to dust off our old reflective target code and use it to get close enough to each yellow tote to make the A/S/L work. We start behind the right tote (as viewed from our alliance wall), A/S/L, back up, drive to the next, A/S/L, back up, drive to the last, A/S/L. Then, to get everything into the auto zone, we spin 180 degrees (we have a gyro) and drive forward until our "curb feelers" find the back scoring platform. Then we back up a few feet, drop the load, and back away a bit more.
  • More TBD. Our grabber should be good at getting a single RC, but not at moving all three, or at getting them from behind the landfill, so we just add some minor variations, such as a tote stacker that works on the alliance wall side rather than the step side, and a driver that also takes advantage of the curb feelers.
