This is the main component for this robot. The most expensive.
You might get them free or pay from 1$ to 4$ each.
the SPDT switchs need to be really sensitive! These switches are the most expensive part of the robot... around 1$ to 4$ each. The one I use are from Cherry.
If you recycle old electronic, it might be all FREE! Try searching old VCR, PS2, old toys, printer, etc
Back then, I use to recycle everything, I got everything FREE, old VCR are very good for gears and something SPDT switchs!!! Playstation have great motors, the one that makes the laser move.
-- edit july 5 2008 I was surfing the website and found this cool instructable

His name is Nick and he is 14 years old!
He told me that is was going to build the beetle robot this weekend because he has all the parts!
He took the time to recycle. :P I did the same thing when I was his age! :)
At the end of his tutorial, I saw a picture of the blue recycling bin of is municipality - Blainville! That is like 10km from where I am living while making my internship!!
The world is small!

KHS Gear Fluid PG 1000 is a high performance, anti-wear gear oil for the lubrication of worm gears, highly loaded gears and applications where high resistance to micro-pitting is needed, for the use in food and beverage processing equipment.
The 2-speed transmission features smaller & lighter parts: carrier for the 2-speed gear, alu drive flange with the 1-way bearing, and gears from the well-proven NT1. All this combines to give better bottom-end power and acceleration.
The 2-speed gear adapter is CNC-machined from Swiss 7075 T6 for precision fitment of the 1-way bearing, and allows for super-precise and wobble-free installation of spur gears. The high-quality 1-way bearing is hand-ground before installation for maximum running precision and strength. The 2-speed adapter is manufactured from hardened steel.
The spur gears are made from graphite material for improved durability. The special graphite material is also very light which helps to decrease the weight of rotating parts for improved acceleration.
The spur gears are molded with a special technique allowing the gears to be absolutely true, thus improving the drivetrain efficiency. Each gear is stamped with a tooth number for easy identification.
