We work on figuring out a light weight design for the "upper" stuff, and don't worry so much about the bottom of the robot. Once you come up with a basic design of how to make the manipulator stuff work, then spend a few more days thinking of ways to make it much lighter, using different materials, design ideas, etc. Our logomotion robot had a very light weight structure holding the arm, and the arm and claw weighed very little, and were made mostly with materials from the local building supply places like Home Depot and Lowes.
Lightweight stuff includes using thinwall square aluminum tubing and ABS sewer pipe, 1/4" plywood, thin Lexan sheet, thin aluminum sheet, etc. Figure out how to put things together with lightweight fastening methods, such as rivets.
