Inexpensive Powerful Router Based Robot

[Andrey Mikhalchuk] Has posted some great instructions on how to build an inexpensive router based robot. Starting with a Linksys WRT54GL, he takes us through the process of disassembling and modifying it to directly control servos.  He has put together a custom version of OpenWRT Linux that you can download from his site.  After testing to make sure everything is functional, he goes through a quick and dirty chassis build.  As you can see from the picture above, there are lot of household items thrown in there such as rubber bands and zip ties.  After adding a camera mounted on two servos for x y movement, he fine tunes it and lets it go.

This project looks fairly simple, cheap, and fun.  It may look familiar as it is very similar to our Wifi Robot post from August.

Crabfu Challenge Winners Announced

The Trossen Robotics Blog has announced the winners of the “Crabfu challenge”. The challenge, issued by [Crabfu] was to make a robot that was full of character. It didn’t have to have a purpose or be autonomous, it just had to be full of character.

The first place winner, pictured above, won us over when he “blinked” a few moments into his video. Strange how something so simple can add so much life. Continue reading “Crabfu Challenge Winners Announced”

Backup DVD Burning Robot

[Aaron Shephard] at mini-itx.com just finished a backup DVD burning robot based on an EPIA M10000 Mini-ITX motherboard and scavenged parts. A Perl script interacts with stepper motors, LEDs, and sensors through the parallel port on the motherboard. The robot inserts DVDs for burning, flips them for labeling, and stacks completed discs in a pile. Coasters are rejected to a ‘penalty box’ for easy disposal.

We’ve also covered some other optical disc duplicators in the past.

Hack A Day Fail Contest Winner

We had a lot of entries for our Fail contest; there can only be one winner though. We liked [Gordon LaPlante]’s entry pictured above most of all. It’s big, it’s broken, and it’s black and white; that certainly sounds like us. [Gordon] wins $100 worth of No Starch Press merchandise.

There were plenty of other honorable entries. You can view them in the Hack a Day Flickr photo pool. We saw a couple themes emerge during the contest and have highlighted some of them after the break. Continue reading “Hack A Day Fail Contest Winner”

Giant Mechanical Spider Awakens In Liverpool

While we were away, we missed the story about the giant mechanical spider in Liverpool.  That spider has come to life, and you can watch the video courtesy of the BBC.

Named La Princesse, she an art project designed to build tourism and boost the economy.  Developed by french company La Machine, she looks amazing.  It looks as though it takes 9 people to pilot her, possibly another running the crane she’s suspended from.  Watch the video and see her reach out and tap an onlooker’s umbrella with one of her legs.

Autonomous Paintball Sentry Gun


[Alan] pointed out this great commercial paintball sentry gun. The gun has a low power motherboard running Ubuntu connected to a firewire camera. Two high torque motors control the pan and tilt of a Tippman 98 custom. The control box allows for easy setup. You can change the sensitivity, color tracking, and firing modes. It also has a remote kill switch. All around a nice looking machine, but at $3K we doubt many of you will be buying one. Beta test video embedded after the break.

British Bots Compete For Attention


The British military held a competition to find the newest batch of robotic surveillance drones. The article mentions that they compete in a mockup village, but sadly we don’t get to see any of the action. We strongly recommend watching the video so you can see some of the robots. There is an interesting helicopter concept that has angled props for better stability and lateral motion, but more importantly you get to see the little guy pictured above. He very well could be Wall-E’s great grandfather. Though his constant buzzing around during the interviews is slightly annoying, his little camera mount looking all around is instantly endearing. If he doesn’t win this contest, he may have a shot at the [crabfu] challenge.
