My study suggests that you need to be about 1/16 or 0.064" sheet Aluminum. 1/8" is too much. 3/8" is a tank for a chassis with no ability to to add anything.

Do a weight study. At most you should have 40 pounds allocated to chassis, gearboxes, motors, chain, and wheels.

Depending on your approach above 8" above the floor, you need a lot of stuff, motors, actuators, hinges, etc. to make an arm or whatever work for you.

Any comments on designing for weight are welcome.
