MATERIALS

Found a neat material useful to making robots? Know how to work it?
Let me know!

Advice on choosing materials for your robot:
Lighter robots are always better. Always.
Lighter robots require smaller motors, hence fewer batteries.
Smaller motors and fewer batteries mean cheaper.
Heavy robots require stronger materials or will tear itself apart.
Lighter robots do less self inflicted damage when ramming walls.
If possible strengthwise, always opt for the lightest materials.

Aluminum
Basic light weight yet strong robot building material.

Balsa Wood
Extremely light weight for flying robots.

Carbon Fiber
Extremely light weight and strong for tiny battlebots and flying robots.

HDPE
Light weight plastic, cheaper than aluminum, and very easy to machine.

Styrofoam
Light weight, easy to shape, and extremely cheap.

Vacuum Forming
Mold polystyrene sheets into ANY light weight shape desired.

Velcro, Tape, and Epoxies
Fastening material used as major structural components.
