This isn't exactly a robot video, but a way to make robot parts with your kitchen oven & vacuum cleaner:

For detailed instructions on how to make the vacuum former (in an hour or so) see the "Instructable":

www.VacuumFormerPlans.comYou might also want to get Doug Walsh's classic little book, "Do It Yourself Vacuum Forming for the Hobbyist." He figured out most of this stuff years before I did. You can get it from
www.build-stuff.com(He's also selling some nice surplus Thomas vacuum pumps, which also work as compressors, for under $100 shipped. They could be useful for robot pneumatics, as well as for a high-powered vacuum former. BTW, I have no stake in that business; I just like his stuff.)
