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.

5 Legged Locomotion

When designing legged robots, we generally see an even number of legs. Mainly, we think, it is due to us modelling things after nature. But with robotics, you’re free to do whatever you want. [Iketomu-san] has built this unsettling 5 legged robot out of parts he had lying around. The gait is fairly interesting. He mentions that it could be used for robot fighting, where the odd leg would serve as a prop from behind and the two legs up front could be weapons. What kind of gait or use can you come up with for this thing?

SpiderBot Prompts Laser Envy

January 21, 2010 by Mike Szczys 14 Comments

[Daniel’s] horrifying hexapod makes us wish we were sitting next to a laser cutter. The parts are cut from 4.9mm plywood and include laser-sculpted sections to allow the twenty servos to properly seat in their mounting spaces. We would suggest that you build it in secret so as not to ruin the surprise when your house mates come home to find this romping around their room.

Sadly, we couldn’t find video of this in action but go look at this other hexapod if the still shots aren’t good enough. Adding two legs to the party, you behold the video after the break of the 8-legged spider milled from ABS.

Robots In Space

SPHERES (Synchronized Position Hold, Engage, Reorient Experimental Satellites) are experimental robots made at MIT for the purpose of testing robot locomotion in space. As you can see in the video above, they are capable of maneuvering pretty well. They seem to hold formation fairly tightly. They are using compressed CO2, through 12 different thrusters for positioning. They should be capable of autonomously navigating around each other as well as docking to one another.

Polymorph In Practice

[Leesam] tipped us off to this cool tutorial for shaping Polymorph. For those who haven’t, it is pretty cool stuff. It is a plastic that comes in little pellets. You can melt it down at relatively low temperatures and mold it to the shape you need. We’ve seen it used on several projects, most notably CrabFu’s swashbot3. Generally, we see it hand shaped, so it is fairly organic and imperfect. It can be used for more precise shapes though. This tutorial walks us through the easiest way to produce sheets of the stuff to be cut and bent into brackets as well as some helpful tips on getting the best results.

The Pololu 3 Servo Hexapod

Here’s a great tutorial on how to make a tiny hexapod walker. While this was written specifically for a kit that is sold by pololu, we like the simple layout. You could implement your own electronics if you prefer something else. If you want to follow along with their components, you’ll end up with a fairly small and decently agile hexapod. Sure the legs aren’t articulated at every joint, but the effect is workable. This is probably the first 3 servo walking hexapod we’ve encountered and we’ve seen a pretty decent amount of hexapods.
