Matthew Borgatti has built an air-powered, 3D-printed robot tentacle that waves in a friendly fashion and lends a helping hand. It is in no way erotic. Nuh-uh, not at all.
So, with a very nice looking tentacle in hand, it was time to start experimenting with robotic air control. I believe I’ve found a system that works in a pretty simple and straightforward way. It still needs some work when it comes to the programming end, but I think the mechanics are well sorted. The idea is to pulse air into the tentacle using a solenoid valve, and have a constant bleed on the line so that flex will entirely be controlled by how long the valve stays on. It’s sort of a low frequency PWM. I’d like to get this working using a visual interface in Processing but, given how little I program, progress has been slow. I’ve got a thread on Adafruit with what I’ve come up with. In the meanwhile, you might like to check a rough video of the trefoil inflating.
You’ll know Ben Hatke as author of Boing Boing-beloved illustrated kids’ books like Little Robot and Zita the Space Girl, but as this Children’s Book Week video shows, Hatke is a literal fire-breathing, acrobatic, sword-fighting superhero!
Rogue archivist Carl Malamud writes, “In 1993, I started a radio station on the Internet, engaging in activities that later became known as podcasting and webcasting. I’m pleased to say that I’ve finished uploaded the archive of Internet Talk Radio to the Internet Archive.”
3D printing has been one of those “next big thing” innovations among early adopters and the tech circle in-crowd for a few years now. However, the prospect of creating your own three-dimensional objects is still in its relative infancy with the general public. While the idea itself is fascinating to most, high prices and the […]
White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
Why buy one of those expensive and confusing universal remotes, clogged with enough buttons to launch a space shuttle, when you could accomplish the same electronic control right on your favorite mobile device? The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
