Tiniest bot, sort of. CNC controlled

tinybot

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.

Microbot for the Robocup 2008

[tioguerra] helped make these tiny bots for the World Robocup 2008 in china. There’s tons of information on the Mixed Reality forum, but you might be specifically interested in the bot section.  There are breakdowns of different aspects, such as charging and IR communication, as well as some great photographs of the unit along with a smaller one. The construction of the robot seems so nicely fit together, someone spent a lot of time getting the design just right.  Since we don’t see a new section for 2009 bots, we are guessing that they’ll use this design again.
