Although it seems like robots modeled after snakes and worms could be used for a wide variety of applications, the majority are designed for only two uses.
Many are created as rescue robots -- for detecting danger or victims or for taking supplies to survivors. Their shape, size, and locomotion style give them access to places people can't or shouldn't go, such as collapsed buildings and nuclear reactors that are damaged or being decommissioned.
The other main use for snake and worm robots is in medical applications. Skinny, snaky tubes are just right for inserting into blood vessels or abdominal cavities to assist in minimally invasive surgery. Or they can go exploring to locate problems such as tumors and send back data about size and location.

The Slim Slime Robot from the Tokyo Institute of Technology's Hirose Fukushima Lab is a pneumatically driven active cord mechanism. It is used to inspect pipes in chemical laboratories or nuclear plants, detect unexploded mines, and help first responders find victims in collapsed buildings. A series of six connected modules are driven by pneumatic actuators. Compressed air is forced from the main tube of each module into that module's bellows, or flexible pneumatic actuators, which are located along the main tube's length. The Slim Slime can creep like a snake, make pivoting turns, roll laterally, and move with a pedal-like motion that emulates snails and limpets. Its total length is 730-1,120mm (28.7-44 inches). It weighs 12kg (26.4 pounds), and its top speed is about 60mm (2.36 inches) per second. (Source: Hirose Fukushima Lab)
Ken, interesting point about fear of snakes. Actually, only some people fear them. I'm not one of them. But spiders absolutely creep me out, and not everyone has that fear either. Some people think it's like a gene allele: you either fear one or the other, but not both.
My kid (thus I) had snakes as 'pets', but it never occurred to me that one might some day get the paper for me!
That said, a 'fear' of snakes is pretty strong and innate in the general population, and I admit to a few internal shudders when looking at these photos.
Real snake locomotion is trully wondrous. I've seen them go right up the trunk of a tree, literally 'look ma, no hands!'. Amazing. I truly admire anyone attempting to mimic it mechanically, they have their work cut out for them.
robatnorcross, I had a similar thought, although I'm not afraid of snakes--unless they're venomous, that is. This one's "skin" pattern is camouflage, but it looks a lot like some venomous western rattlers I've seen. Even without fear of snakes, this would still give one pause if you were trapped and couldn't move.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
