hehe, well LOLA my teams stacker bot is competing tomorrow. We've been working hard on the code to make stacking easy. So hopefully we will be able to stack quickly and well. we have some nice advantages which a lot of other robots didn't have. A cavity to protect our stack, and a flexible(it can pick up and use boxes on most sides) arm. We have a maximum hieght of 6 high for top stacking. Also we have a vector drive to line up the grabbing of boxes quickly and to use our arm as a giant wing.
I can't weight to see our robot in competition.
