25C3: Cheap Swarm Robotics

swarm-2

The Formica project was our favorite presentation at 25C3. The goal is to build open source swarm robots as cheaply as possible. The team ended up building 25 robots in an assembly line fashion. With enough lead time, the price could get as low as £15 each. Each bot has two direct drive cellphone vibration motors with tiny neoprene wheels. They’re controlled by an MSP430 microcontroller. The only really specialized chip is a charge controller so the bots can charge without any intervention. They have copper skis on the front that touch the ground plane plus antennas to contact Vcc. On top of the bot are three IR detectors for both navigation and for transferring firmware updates between bots. A reflective sensor is on the underside for detecting “food”. It looks like a great design and any easy way for anyone to start researching swarm robotics.

How To Properly Dispose Of Fruitcake

While doing serious fruitcake research, (no, really) we stumbled across the Great Fruitcake Toss held every January in Colorado. The particular entry above caught our eye. Omega 380 was built by a group of Boeing engineers and currently holds the distance record of 1,420feet. It’s a large compressed air cannon. All pressure is human generated using an exercise bike turning a pump. Apparently the team’s first contest entry was a classic surgical tubing slingshot. It eventually broke down during a very cold year, so they switched to this newer design. You can see more videos on the Operation Fruitcake blog.

MBTA Drops Lawsuit Against MIT Subway Hackers

December 23, 2008 by Eliot 8 Comments

The Massachusetts Bay Transit Authority (MBTA) has dropped its federal case against three MIT researchers, “the subway hackers”. This happened in October and now the EFF brings news that the students will be working with the MBTA to improve their system. The overall goal is to raise security while keeping expenses minimal.

This whole mess started in August when a gag order was issued against the students’ presentation at Defcon. It’s a shame no one ever saw it because it covers a lot of interesting ground. A PDF of the banned slides is still online. They performed several attacks against both the subway’s fare system and physical security. Our favorites by far were using GNU Radio to sniff the RFID card’s transaction and bruteforcing Mifare Classic with an FPGA.

Year In Ideas

The New York Times has published their 8th annual Year in Ideas. It’s a collection of interesting research and policy changes that have happened in the last year. They cover several projects that we’ve found noteworthy in the past. Pictured above is [Max Donelan]’s power generating knee brace. It generates power as you perform mundane daily activities. Another pick was the Brickley Engine. It has a unique piston layout to reduce friction for increased efficiency. We were particularly interested in the research that discovered drone pilots become exhausted far quicker than pilots in real aircraft. It’s doubtful that this problem of “sensory isolation” will go away and we wonder what other fields it might appear in. They even mention [Josh Klein]’s crow vending machine. You’ll find something to pique your interest in the Year of Ideas, even if it’s DNA forensics for dog poop.

MINI’s Augmented Reality Ad

We were surprised last month when we saw augmented reality being done completely in flash. It hasn’t taken too long to go mainstream though. MINI has incorporated it into a recent German language magazine ad campaign. The fiduciary marks actually work quite well with MINI’s established ad format. Visit the ad’s URL and hold the magazine up to the webcam and a 3D model of the MINI Cabrio will appear. They have a PDF of the ad that you can print and use if you don’t have the original. Unfortunately, it doesn’t seem to have cross-platform support.

Walk/drive A Dog/motorcycle

robo-dog1

This hulking monster was created by the Mutoid Waste Company because, well, why not? Part dog, part motorcycle it walks/drives and breathes fire. Constructed from all salvaged parts, this thing is a testament to recycling. Either that or it is the harbinger of the robot apocalypse. Regardless of the possibility of it enslaving all mankind, we want one. Be sure to watch the video.

Ripsaw MS1

The Ripsaw MS1 is an unmanned ground vehicle built by two brothers in Maine. The tracked vehicle can go 0-60 in 3.5 seconds with an 80mph top speed. In its current form, it has a 2000 pound capacity, which opens the possibility for many different types of weapon systems. Control is provided by two people: one driver and one gunner. They work in independent remote stations. The Ripsaw could potentially be used in any application normally reserved for a tank. It could lead a charge without putting soldiers at risk.

We’ve been watching this project mature since 2005 when it was being marketed as a Grand Challenge competitor. This week it’s being demoed at the Army Science Conference. Check out footage of it in motion below.
