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.http://www.cherrycorp.com/english/switches/sealed/dcjk.htm
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 instructablehttps://www.instructables.com/id/Recycle-old-PCB-components/
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!!
