Here’s an interesting concept, the bot pictured above has no internal control mechanisms. His claims to have built the smallest bot are dubious, considering it requires a much larger control platform to function, so lets just set that aside and look at how it works. The bot itself is basically a hollow box with a hinged manipulator mounted on it. He has then built a modified CNC type structure with various magnets below a platform. The magnets can move the bot and control the manipulator (assuming the bot isn’t trying to pick up anything magnetic). He talks about this being a possible control scheme for smaller bots, though we think he would have to make some major advancements to his magnetic controls for accuracy’s sake. As for his claims of being the smallest, well, we’re sure we’ve seem similarly sized bots, even hexapods, that were completely self contained.

Self-portrait Machine
[Jen Hui Liao] created a device that guides the user into drawing a portrait of themselves. Dubbed Self-Portrait Machine, it comments on how much in society is created by machines and we are dependent on them. Unlike previous drawing robots, the user is part of the sketching process. The machine holds the users hands and uses stepper motors and servos to move them around like a LOGO turtle. Liao promises to have more details available soon. Video of the machine after the jump.
Motöri The Plotter

The Motori plotter is fast and high precision. One image shows that it is drawing lines at .5mm. Like others in the flickr set, we keep thinking of how we could apply this to PCB creation. Great job [svofski]. If you want one that’s not as precise, but might have a much cooler drawing mechanism, you might want to check out the lego arm plotter we posted back in May.
Kali The Makerbot
Is this the beginning of a new trend? We’ve seen case modding in computers for a while now, but are we going to start seeing extreme case modding for our CNC machines? This is Kali. Kali eats plastic and pukes parts. Nice.
Rapid Prototyping With Sugar And Lasers
After the recent announcement of the re-release of the candyfab, [4volt] had to give a run at melting sugar with a laser. It turns out that a 40w co2 laser works great. They don’t currently have a method of layering, so everything is one layer currently.You can see the results of different speeds and power ratings on the site. The next party they throw will have some pretty fancy tasty treats.
CandyFab Relaunched
Forget about machines that can replicate themselves, what we want is a machine capable of making an 8 inch wide hollow torus out of sugar. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the new wiki site.
Ghost Matrix, Glow Printing

Ok, there aren’t any usefull applications we can think of for this one, but we want one really badly. This is a combination of a miniPOV, some UV LEDs, a CNC rig, and some glow in the dark paper. The Ghost matrix works similar to a dot matrix printer where it flashes the UV light to activate the paper. The final effect is very nice. Great job on this one.
