This tip was submitted by [Mike], with the original information seen in this post. When I passed the story along to our writer [Mike Szczys] I didn’t send along the entire email conversation. This bot is noteworthy because it has taught itself to walk. In the build log you can learn about how it has created its gait and altered it based off of the vision. There are also some great pictures of prototypes there too. While we can all agree that it isn’t as impressive looking initially as the A-Pod, remember that it wasn’t programmed to look impressive.

Veteran Robot Features Eight Legs And BeagleBoard

February 11, 2010 by Mike Szczys 18 Comments

This spider-bot was built by [Zhanx] during his deployment in Iraq. He didn’t have prior hardware building experience and started out on this project when he received an Arduino to play with in September. Must be a fast learner! The parts are laser-cut from ABS plastic and connected to 24 servos. He sourced an SSC-32 serial servo control board to take care of the motor connections.

[Zhanx] has since migrated from the Arduino to a BeagleBoard which you can see perched atop the body in the video after the break. This should give him plenty of speed and power to improve the movement routines. There’s some nice work here but adding rubber feet, like on yesterday’s hexapod, wouldn’t hurt.

Dexterous Hexapod Rocks An Atom Processor

[Matt Bunting’s] hexapod caught Intel’s eye (and their wallet). This coordinated little bot runs Ubuntu on an Atom Z530 processor, popular in netbooks like the Dell Mini 10, and uses a webcam to coordinate and monitor its motion. Intel picked up two of them from [Matt] to exhibit at trade shows. As you can see, the 18 servos provide some gorgeous motion to the beast. It’s no DJ Roomba but it approaches the zen-like perfection that is the A-Pod.

Lego Spider-bot

February 3, 2010 by Mike Szczys 11 Comments

[MkMan’s] LEGO spider robot combines pieces from a Mindstorm kit with a few milled plastic parts. The legs are a locomotive concept called a Klann Linkage. They operate in pairs and convert the rotational force from one motor into movement for two legs. Here, a total of four rotating gears moves eight legs, besting the hexapods we saw a couple of weeks ago in both leg count and motor economy.

Each limb is made up of five pieces plus one base for each pair. That makes eleven pieces per pair and a total of 44 for the entire robot. [MkMan] milled these parts out of 3/8″ HDPE stock. He’s made videos of forward motion and turning which we’ve embedded after the break. Even on a polished surface the bot looks fairly efficient at getting around.

Icosatetrapedal Robot

24, Icosatetrapeds have 24 legs. This robot, built by [Monica Anderson] back in 2005 has 24 pneumatic soft legs. The motion is fantastic, like watching some kind of sea creature walk. Though it only goes about 1 meter per minute, we just couldn’t stop watching. The compressors were scavenged from some military equipment designed for nerve gas detection, and the brain is a mac mini. The rest is just valves, solenoids, wood, and tube.

Snow Blower Robot

February 1, 2010 by Caleb Kraft 23 Comments

For those of us who are stuck in the middle of a cold and snowy winter, this project will seem like a stroke of genius. [Jimmy Bui] has put together this robotic pushing platform. While it is seen in the video (on the linked page) pushing a snow blower, it seems to be simply bolted on. This means it could push pretty much anything, such as a lawn mower. The platform itself looks like a common layout. He’s using the base of a motorized wheel chair, and some scavenged bits to protect the circuitry. He says that he built it after seeing elderly people having a hard time shoveling their driveways in his neighborhood. They don’t say if he loans it out to them now, but we suspect that he does.

Robot Band Gives Us So Much To Make Fun Of

January 30, 2010 by Mike Szczys 14 Comments

[Pat Metheny] has a robot armada backing him up when he performs on stage. They’re going on tour and he’s done an interview explaining his mechanical band. Like the auto-drummer, this setup uses multitudes of solenoids to play the percussion instruments, each getting commands from a computer. It’s pretty wicked to see him use his guitar as a marimba controller; it’s so responsive that he can tremolo and the solenoid follows in kind.

But there’s a lot more going on here. We love to see crazy facial hair from time-to-time, but this guy’s just got crazy hair! This easy listening isn’t exactly hair-band material but more like live-action Animusic. It’s also reminiscent of the automated orchestras at House on the Rock, an attraction you may remember reading about in American Gods. It’s fun to kid, but whether you like the music or not, he’s certainly talented when it comes to this genre.

[Thanks Grey]
