Electric Screwdriver Robot Hand

August 1, 2008 by 1 Comment


Here’s an interesting grabber hand built for use on an ROV. This grabber is a novel use of a very common and extremely cheap electric screwdriver, that is probably found in everyone’s toolbox. It is also a great way to reuse that small electric screwdriver you have kicking around that uses proprietary batteries that are not worth replacing. Many of the ROV’s covered previously could benefit from such a powerful device built from very common materials off his parts list. Because the screwdriver was extremely cheap the designer chose not to completely seal the housing.

It seems like this simple design that could be used in many robotic projects and by simply changing the jaws could yield other creative uses. The first thing that comes to mind is to upsize this hack into something bigger and stronger. Either way, you might not want to get your fingers in there.

Robot Red Snapper

July 30, 2008 by 8 Comments


Engineers at the University of Kitakyushu have built this red snapper robot. Intended for wildlife surveys, this robot sports an array of sensors as well as a hand painted silicon body. It is decidedly more realistic looking than the Robofish and the Essex University robot fish. They say that the life like construction will aid in getting information about natural behavior of sea animals since it won’t stand out. It features a “unique” propulsion system that allows it to swim like a real fish. More information on that system would be nice. You can see more pictures of it here, but the descriptions are all in Japanese.

Hackit: Crap Modding

July 29, 2008 by 30 Comments

When Boing Boing Gadgets posted about this $13 robot hand music box, we immediately thought “OH EXPLOITABLE!”. Over the years, we’ve acquired quite a bit of cheap trash just operating under the assumption that we would turn it into something else. Most of our acquisitions are Woot‘s fault. Just this morning we were dismayed to find out that the purveyor of cheap electronics had already sold out of animatronic Elvis heads. Now that would have been fun. We’ve purchased things like Tony Hawk helmet cams, jumbo remotes, Bluetooth headphones, Gyration mice, IMFree chatpads, and many other items of questionable use thinking that some day we’d use it. How about you? What sort of irrational purchases have you made and what would you do with a $13 mechanized hand?

[Just as we were wrapping this up, Woot posted a $49 HMD; you better believe we bought that.]

Build A ROBONOVA-I

July 23, 2008 by 14 Comments


On the latest episode of Systm, they talk to [David Calkins], founder of the RoboGames competition, about humanoid robotics. The robots featured in the episode are Hitec’s ROBONOVA-I. The ROBONOVA is about a foot high and has 16 servos with support for up to 24, all connected to an Atmel controller. The episode is quite long: At around 15 minutes, they demonstrate the programming enviroment. You can program it traditionally or pose the bot to work out the motions. At 30 minutes, [David] mentions that next year’s competition will allow airsoft weapons to be attached, but bots have to be controlled from a first person perspective. If you’re interested in one of these kits, they have a ROBONOVA special of $900 or as low as $500 for educational institutions (that’s us, right?). Now is the perfect time to get one since you’ll have nearly a full year to prepare for RoboGames.

BiPed Robot Version 3

July 11, 2008 by 4 Comments

Instructables user [alex.v] posted version 3 of his BiPed Robot. This robot is designed to mimic the control and movements of a human’s lower body. It has 12 degrees of freedom and a nice custom framework CNC’d from acryl sheets. The electronics consist of servos controlled by a custom board built around an ATmega8 and 3 ATtiny26s all programmed in assembly. He also has custom desktop software written in VB which allows direct control of the robot and graphs sensor data. His site contains pictures, videos, and design materials.

7 Really Creepy Robots

July 11, 2008 by 1 Comment


Creepiness is a hard feeling to objectively evaluate, but we dare you to not get creeped out by these realistic robots listed by Cracked.com. It’s the uncanny valley of robots that are almost, but not completely lifelike, and which repulse most humans. It begs the question: how could you resolve the uncanny valley problem? Would you build a robot to look exactly like you, as [Hiroshi Ishiguro] did, or would you build one to look like a famous figure, like the Albert Hubo?

Dancing Wall-E And Rhythmic Synth

July 10, 2008 by 9 Comments


Whether you loved, hated, or didn’t see Wall-E, it’s hard not to fall in love with the iDance Wall-E toy. Connect him to an audio source and Wall-E will dance around like an epileptic Billy Bass.

[Gian Pablo Villamil] at NYC Resistor wondered whether it would work with his custom made Rhythmic Synth, and to his and our delight, it does! The Rhythmic Synth is an older project of his; it is a simple rhythm generator with 4 pitch knobs, 4 modulation knobs, and 4 phase switches. The case was taken from an old external Iomega CD-ROM drive.

Getting the Wall-E to dance isn’t much of a feat, but something about the dancing combined with a synth with embedded lights just screams robot dance party, and that can never be wrong. We’d love to see the Wall-E dancing to a cleaner, more complete synth: maybe this one. Check out Wall-E busting a move after the break.
