We've been all across the board.

96. ALL WOOD. Even the wheels!
97. Wood/Steel frame Hybrid. This bot Rocked! 2nd place in NJ
98. All Steel frame, all alumin upper chassis. 2nd in NJ again
99. again, all steel, and alumnin upper chassis
00. Aluminin Frame. Actually, the whole bot was aluminin
01. Aluminin / Bosch Hybrid
02. All Bosch. She was a tad heavy, but we have never had a bot that wasn't within a few ounces of the limit.

Another funny correlation. 96 and 02 had the same drive train, two wheels.
all the other years had skid steer. (Think like a tank)
