We were actually supposed to receive the EDU yesterday but it arrived today. Wonder what went on?

FIRST used ground shipping.
I FINALLY got to the point of being able to compile and upload to the new eduRC. Whew.
And, the results are really cool. While we still don't have our R/C controller yet, I programmed it to do a few things. First off, I'm using my crab-drive edubot that I built before we got the new controller. I've gotten it to basically strafe around in different shapes, circles, triangles, squares, etc.
I'm having a bit of a problem w. the servos though...
The Range of the pwmXX variables is still 0-255, right? For some reason, The HiTec Servos from last year's kit wont go all the way around to 0 when 0 is sent, and wont go all the way around to the other end at 255. They do center at 127, though. I tried a few different things, but I'm still having some issues getting them to go from 0 deg (0) to 90 (127) to 180 (255). And Yes, I know that the servos actually have over 180 degrees of rotation, so these numbers aren't 100% correct, but the problem is that they won't move enough. I'm not sure why. In all my previous work with servos, I haven't had this problem...
Anywho, I'm trying to find a small portion of free web space I can link to to post up some video of the bot in action. We're still in the process of getting our "new" domain set up.
