What size 80/20 did you use? It looks like the 1.5" x 1.5" 80/20 was used for everything. You can use the 1" x 1" 80/20 for most of the chassis frame to help save weight. If you want to try to cut back on the weight of the robot, here are a few helpful ideas:

There are a lot of "extra" 80/20 pieces on the robot that you might be able to take off if other joints are strengthened. Also, if you have the machining facilities used to mill the holes for the 80/20 corner joints, you might be able to machine pillow blocks for the axles out of regular aluminum stock rather than 80/20, as it may save you a bit of weight. On some of the 80/20 members on the frame, they overlap another piece. You can knock off a few inches of the 80/20 (and knock off a bit more weight) by having all the joints be "butt joints" that join together in the same plane (rather than skewed joints).

Otherwise, this looks very nice for a robot built in a month, let alone by a rookie team. You guys should do well this year.
