Perhaps, I don't know since we didnt win the competition.... We may just to be able to have a base to be able to experiment with AI and obstacle avoidance. -- andrew (with my 7 month daughter playing with the keyboard and mouse as I try to type.) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
