In past years, we always had a problem with weight.
In 1999 we finally got smart and decided to plan for weight reduction in every single part.

Rule #1:
Every single part that can be legally modified can be made lighter. Most off the shelf parts are over-designed for our applications (ie.we webbed out all the gears that we bought).

Rule #2:
Know thy densities:
Steel = 0.3 lbs/cu-in
Aluminum = 0.1 lbs/cu-in
Lexan = 0.045 lbs/cu-in
PVC = 0.05 lbs/cu-in
Aluminum can replace steel in 90% of your applications.
Lexan is heavier than you think - don't make it too thick. 1/4' Lexan is much heavier than .060' Aluminum.

Rule #3:
A robot looks cooler when it has a structural look that you get by putting symmetric hole patterns in your large sheet parts.
