back in 1999, our robot had a 'net' made of 1/32" lexan strips, 1" wide. There were over a dozen linear feet of these strips. I was one of the team of students that used an industrial hole punch to knock out as much weight as possible from those strips (yes, we had gotten down to that). We punched about 2000 holes in a hexagon pattern by hand.

we also trimmed all the clear parts of our logo out of the 1/32" poly sheets they were glued to, saving another few ounces.


I also recall that we used hanging scales that year, two of them to weigh the whole robot. We were still overweight by 6 lbs a day before ship, the team went back to work trying to find more things to remove, and then I noticed that we tared the scales right side up, but used them upside-down (including the weight of the scales in the robot measurement). Since they were borrowed from the shop at the power plant, they were exactly a kilo each, so I saved us 4.4 lbs. The remaining 1.6 pounds meant the loss of a mechanism, though (we had two ways onto the puck that year, and removed one).
