I'll buy at least one!
But it really should include
team 1899. Using laser cutter, common "door skin" plywood, a bit of epoxy and some brilliant CAD, they have created the lightest, stiffest, cheapest robot frame at worlds.
Okay... technically I haven't seen
all the robot chassis going to worlds, let alone conducted stress tests and detailed financial analysis of them, but I'm more than confident that they deserve to be "in the book".
And, for the record... this isn't one of those million dollar lasers that cuts steel... this is a relatively affordable wood/plastic type of machine. I encourage you to try standing on one of their backup chassis!
