If anyone remembers our 2001 bot, it had an arm with a range of motion close to 180 degrees and a rotating wrist at the end of it. Meaning that, when positioned the right way, the arm could lift the front two wheels off of the ground. I wish I had a picture of us doing this, but if you look in the CD galleries you should be able to get an idea of what I'm talking about. Although it hasn't been tested, I'm sure that it would be able to lift the front wheels enough to get up the step. Then it could rotate the arm 180 degrees to lift the back wheels up enough to get up the step. This would only be possible with a bot with 4 wheel drive though.
