Halloween Prop: The Ground-breaker

[casafear1] has put out this video detailing how to build the “ground-breaker”, a zombie escaping from the grave. It is a simple frame for the arms and shoulders, with a couple pneumatic pistons to make it jerk as though it were pulling itself from the grave. He goes into a decent amount of detail explaining the physical construction, offering several tips to prolong the life of this prop. Unfortunately, he doesn’t enlighten us as to his control scheme. Is it manually controlled? Is it automated? Does it get activated by passers by or is it always going?

Last year, we posted most of the Halloween projects after Halloween. This year we would like to try to get you those ideas and inspiration far enough ahead of time to help you put them to use. Send us your favorite Halloween projects so we can get them published.

Radio Controlled Beetle Flight Footage

September 25, 2009 by Mike Szczys 33 Comments

Earlier this year we were amazed when University of California researchers controlled a beetle via electrical implants. The video available at the time of the original report showed beetles tethered in place while electrical stimuli was applied via the chip. New video of free flight is has now been posted. Although the motion is rather sporadic, it is obvious that simple commands to start flight, stop flight, and turn left or right are having their intended effect. Check out this cyborg action after the break. Is DARPA one step closer to unleashing legions of insect warriors on unsuspecting masses? Continue reading “Radio Controlled Beetle Flight Footage” →

Junk Bots Win Awards In Vietnam

In a national competition for creativeness in children, junk bots have reigned supreme. Pictured above is a detail from one of [Vu Van Thankg]’s junk bots. Created entirely from parts pulled from the trash, this thing has 11 motors which supposedly allow full arm and hand control. We know you’ll be upset at how little information there is, but the pictures alone show so much. Just look at the rig he put together for this arm. If that isn’t inspiring, we don’t know what is.

Pool-playing Robot + ARpool

Enjoy losing at pool? Well the folks at Queen’s University just made it a whole lot easier. The Deep Green robot was created with the purpose of playing a flawless game, allowing it to beat even the most skilled human players. More than a couple of research papers have been written on the project. A ceiling-mounted Canon 350D tracks the position of all of the balls, in addition to another cue-mounted cam (for higher shot accuracy). Using a bunch of calculations, and a computer (probably more advanced than an Arduino), the Deep Green is able to strategize and play. Very well.

On a positive note, another team from Queens is working on a seperate but related project: ARpool (as in augmented reality). It was created to make playing pool easier. The website does not provide much info, but it seems to project different moves onto the pool table, allowing an inexperienced player to tell whether a shot is at all possible.

Mail-E Email Checker

[Totoro] sent in this cool little email notification device he made. Using a paper model of Wall-E, he added some servos and connected it to his computer using a PIC. Mail-E has independent arm rotation and head rotation. He admits that the PIC processor is major overkill and plans some upgrades such as making it wireless and using a little better suited chip to control it. Not bad for a proof of concept.

The Blind Juggler

The Blind Juggler is a robot that juggles or bounces balls in a controlled manner without any sensory input. It is basically just a linear actuator with a paddle on the end to smack the ball back into the air as it returns to the ground. The crazy thing is, it is doing this based purely on pre programmed math. There are no sensors telling it to make any adjustments. While we could envision this functioning, we would never have expected it to be as stable as it is. You can see in the video above that they can actually move the entire robot around while maintaining the bounce. Also check out the pendulum version, instead of just actuating vertically, it is mounted as a pendulum allowing the ball to travel back and forth in an arc.

Bar2d2 On The Discovery Channel

Happy-hour

The friendly robotic bartender we’ve covered a couple of times before hit the airwaves last week. [Jamie], the inventor of Bar2d2 sent in a link to video of the barkeeper in action. The story runs from 0:30-4:40 and covers a bit about the build, the conversion to automatic drink mixing, and plenty of happy liquor-guzzling party goers.

We get a good look at the drink ordering interface called Lazy Drinker. It runs on a laptop and communicates wirelessly with Bar2d2. Looks like you can get your hands on the software for free but the hardware, either in kit form or assembled, is going to cost you. Want to see how the dispenser kits are put together? Don’t miss the illustrated assembly instructions.
