ChemBot: a blob-like, shape-shifting robot that inflates and deflates

admin — Wed, 21 Oct 2009 15:03:07 +0000

Here is a robot that is the first of it’s kind, and a little odd too. This is a blob-like robot that inflates and deflates different areas of the outer body in order to roll a certain direction. The robotic shape-shifting principle is similar to the older robotic wheel design, these robots basically are always “tumbling over” rather than rolling. In order to maintain a constant rolling motion, they basically are in a constant state of “falling over” in a controlled direction. However in contrast to the older wheel design, this robot cannot fall on it’s side because it can roll in any axis. Also, this robot is capable of becoming extremely flat in order to fit under or through something. It’s a brilliant design and is capable of many new kinds of applications. At this point most the development is geared toward the military since there is a demand from DARPA for new kinds of spider-like robots. Some of these new robots could get pretty scary!

Modular Snake Robot

Here is a snake for those of you that don’t like reptiles! It’s not slimy (though snakes never are), and it can’t bite, but it does move like one! Perhaps it even moves better than a snake because it knows how to roll instead of just sliding. This prototype it being studied by the Biorobotics Lab at Carnegie Mellon University. This robotic snake has the ability to climb up poles and inside of pipes and perform reconnaissance missions that no human could ever do. This snake robot is even capable of crawling, climbing, and swimming! That’s right, this robot will even climb up cracks or pipes or even swim through water like a real snake! This robot is designed using servos purchasable at hobby stores with some slight modifications. The chassis is built using a simple aluminum frame even you could make. Using common easy to purchase parts make these robots lower cost and easier to repair. Lower cost means it’s easier for people to buy them, and may possibly allow them to be commercially available. But the other cool part is that it may even be cheap enough to build your own simple prototype using the Parallax Propeller chip. The Parallax Propeller chip is perfectly suitable for this application because it even supports video which is necessary on this type of reconnaissance mission. Go for it, I think it a good idea.
