Beer Shooting Dorm Fridge

When we first heard the parts list for this project, we weren’t too impressed. It has an iPhone connecting to an IObridge etc… But then we heard the next, and most important part, an air cannon and an assortment of beer. We were sold. As you can see in the video after the break, a fancy iPhone interface lets you select your beer, then dispense it into the cannon for delivery. The next step is to aim using a web cam mounted at the cannon and let ‘er rip! The beer is fired across the room and into your hands. We suspect that the amount of cranial injury, holes in the drywall, and shattered glass will greatly increase in frequency as the night goes on. Awesome.

How To Be A Dinosaur For Christmas

December 21, 2010 by James Munns 22 Comments

Well, this metal suit might not make you a dinosaur, but it would be perfectly possible for you to play one on your computer. Retailing on eBay for a mere $2,397.99 OBO (plus Freight for a 350 pound box), this device was made and used for the motion capture of Ugobe’s Pleo Robot. With the right external components (no word on what those are), it would be perfectly possible to get this suit up an going back on Motion Capture as all the onboard electronics are included. This setup would be perfect for anyone planning an animated dinosaur movie that needs some reference movements, or for any mad ~~scientist~~ engineer who needs a control rig for a 40 story robotic dino of death. The possibilities are endless!

The Heinz Automato

December 17, 2010 by Chris Nelson 27 Comments

[Bill Fienup] and [Barry Kudrowitz]’s robots, The Automatos, have been leaving a sticky path of destruction all over the internet. Their sole purpose: to crap ketchup. They accomplish this feat by dumping a CO2 cartridge into a ketchup bottle at the push of a button, leading to some pretty awesome results. While the details are a little sparse it appears that they are using RC cars for the base and a small air gun CO2 cartridge to push the ketchup. The latest version aka the Atuomato 4 appears to be multi-actuated and can shoot more than once for maximum ketchup proliferation. See some videos of it in action after the break.

Inventing Robot Athletes

December 14, 2010 by Mike Szczys 19 Comments

The human body is an amazing instrument from an engineering standpoint. Replicating just one part of it proves extremely difficult but these athletic legs show a lot of promise. This is the work of a Japanese researcher named [Ryuma Niiyama]. He’s been working on the design for years, and is now using pneumatic actuators to mimic the muscles in a human leg. The lower portion of the leg uses a spring mechanism that resembles some running prosthetics currently in use. These serve as a spring to store energy and reuse it by bouncing against the ground. He’s trying to teach his robot to use these legs; taking it through a learning process necessary to use the thigh actuators for locomotion and balance. We were surprised at how life-like the motion in the video after the break is. Even when falling down the movements are very life-like. We thought the movements of Little Dog were real enough to be creepy, and this robot may be close enough to our own mannerisms to fall into the uncanny valley.

Kids Type With Their Eyes, Robot Arm Prints Their Words

December 11, 2010 by Mike Szczys 12 Comments

F.A.T. took it to the next level, combining a couple of their projects for the Cinekid festival. This contraption lets kids write their names with their eyes for printing by a robot arm. The first part is a glasses-free version of the EyeWriter, originally developed as an assistive technology. The system uses some IR LEDs to generate a reflection on your eye that a PS3 camera can pick up and use to precisely track your gaze. Just look at each key on a virtual keyboard to spell out your message. From there, a robot arm used previously in the Robotagger project prints out the name on a big sheet of paper the kids can take home. This is cool, but more importantly it’s a great way to inspire the next generation of hackers and engineers. Check out the video after the break.

Next-Level Robotic Hijinx

December 3, 2010 by Joseph Thibodeau 10 Comments

Oberon is a wheeled remotely operated vehicle that [LucidScience] built based on an electric wheelchair. The detailed and helpful build log is valuable enough even before considering the vast potential of Oberon’s intended use: strutting around town, scaring the neighbours.

We’ve seen other ROVs before, of course, but none with the same kind of War of the Worlds “real-life invasion” kitch. Running down hapless pedestrians or raining hell upon your enemies are great and all, but once you’ve destroyed the surrounding population you’re out of laughs. Not so with Oberon, with which you can convince Mr. Nutcase down the road to go on wild quests for the glory of the new robot empire. The fun doesn’t stop there–enjoy the Hubbard side of life by starting a cult to worship the great Oberon and enjoy decades of financial payoff and moral depravity…all from the comfort of your own living room!

It would be wicked rad if we could move forward with this idea by combining the abilities of specialized ROVs like this camera-bot and this termite-killer-bot. Face it, who wouldn’t want a smooth-talking camera-snapping chemical-spraying avatar for christmas?

Pencil Balancer A Bit Noisy For Desk Use

November 30, 2010 by Mike Szczys 22 Comments

Who wouldn’t want to install this little bot as your newest pencil holder? Place a pencil tip-down and it will keep it from falling using two motors. There is a Dynamic Vision Sensor for each axis that provides feedback, but it’s not the same as using a camera. These sensors pick up changes in pixel contrast, outputting a positive or negative number based on the direction the pencil is beginning to fall. An NXP2103 running at 64 MHz reads in the values and drives the pair of servo motors accordingly.

If you’re interested in the nitty-gritty the full paper is available from the page linked above. It goes into great detail about the algorithm used, and includes plots and histograms showing the data capture during a balancing session. Or you can skip the eggheaded exercises and watch the video after the break.
