Yours truly is about to teach a mixed media class and wanted to try making some stamps to enhance my (and my students') collaging experience. Stamps are used to create background patterns and give interest to surface design in 2d mixed media techniques. There is a variety of stamps available both online and in craft […]
Frogbots! Solar-powered, at that!

I missed the full segment of this story last weeks on "Discovery Channel's @discovery.ca" program, but fortunately, the've put the segment online at their website. I seems that JPL (Jet Propulsion Laboratories - NASA essentially) is working on a solar-powered, single-footed robot frog. This seems like a GREAT idea for extra-terrestrial planet-surface locomotion. Check out the videos and see for yourself. Additional information at Space.com Even more technical information is here and here, in these Adobe Acrobat files from one of the researchers, Paulo Fiorini. Here's his homepage. And this is his dedicated Frogbot hompage - lots of interesting info!
Oh, and if you scroll to the bottom of the Discovery Channel / EXN page, you'll find a nice video clip of our favorite Roboticist, Mark Tilden. They shot this a few years ago, and I'm glad to see they resurrected it to be on this page.

Escaps back in stock!

A little while ago we received an email from an observant Mr. Pavel Ryabinkov, the site-admin of www.myROBOT.ru, who was asking us to relay a question to Mark Tilden: Could you answer, can it be considered the official date of birth BEAM-robotics November 10, 1989?I was basing this question on the message Brian O. Bush: […]
