Slideshow: Robotic Snakes & Worms Get Under Your Skin
2/5/2013

Image 1 of 10      Next >

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)

Ah, I wondered about the Slinky and actually suspected it might still be out there amusing children and adults alike! So I guess I'm not so old after all. ;)

Dated?

Yes, slinkys are still around.  The one I bought my kids years back was plastic.

MY slinky was metal, and didn't have one of those sissy clamps on each end to keep you from poking yourself.

Liz, I believe Slinkies still exist, don't they? So we'll cut you some slack on the issue of that being a "dated" observation.

Everything dates everyone, doesn't it? But I'm with you--I can imagine an engineer looking at Slinky's movements and wondering how to motorize and automate them. First there's a design that uses a helical shape, gravity, and momentum, and then the big jump to motors.

Chuck, I agree--that's one of the applications on a general level: inspecting things in nuclear power plants.

Exactly! That was my first thought, too! I guess that dates us, doesn't it? But it is interesting to see how the movement of that simple toy was a precursor for what's being done in robotics...and that toy moved simply on design alone without actuators. I guess you never know where inspiration will come from or how these things evolve.

Still, I'm sure it would have been useful at the Fukushima nuclear plant, Ann.

Here's a shorter link to a video of that Israeli army spy snake: http://www.youtube.com/watch?v=8t2nFHjtIJQ

That's cute--I thought it was cammo.The head also looks a bit like it resembles a gas-mask.

Don't forget the snake/worm robots in surgery. http://www.designnews.com/author.asp?section_id=1386&doc_id=258121

 

That sort of mobility will push the medical field into new, and I imagine uncomfortable, areas.
