Three-Legged Robot Uses Exploding Body to Jump

Posted February 07, 2013 12:38 PM

From New Scientist:

Pumping air through a rubbery robot allows it to walk, but now you can make one jump by setting off explosions inside its body.

George Whitesides from Harvard University and colleagues have created a three-legged robot lined with tubes filled with a mixture of methane and oxygen. When an electrical spark ignites the gases, the combustion reaction generates bursts of pressure that propel the robot aloft (see video above). "By actuating all three legs simultaneously, we caused the robot to jump more than 30 times its height," write the team. As the height of the jump was limited by the size of the experimental chamber, they think it could spring twice as high without the attached tubing.

Using explosions allows the robot to move much more rapidly than it could with locomotion driven by compressed air. The experiments show that its silicone body can withstand the forces and temperatures generated by the burning gas.

More and more evidence that the most PRACTICAL robots will probably never look very humanoid. And if we want something to work for us for no feed, little time off, and without having to provide it a warm bed and roof, I would think we would NOT want it to look like us. Too many memories of slavery might be engendered by that. But not by a brilliant, and brilliantly conceived MACHINE, no matter how much we might rely on it.

Glad to see we're moving further away from the Utopic view of robot as replacement for man, into the real (realler, is that a word?) world of robot as extremely capable specialist machine.

We may still find places for humanoid robots (Asia seems to be making a lot of inroad here, but I still can't see how much is well-groomed hype, and how much will actually become useful in its own specialized way, for the masses, instead of only for the wealthy who could afford and expensive pretty toy) but I think the mass market for robots at all economic and functional levels of society will be focused on non-anthropoid designs.

Personal opinion, undoubtedly colored by a non-artistic/pro-practical-functionality view of life. I don't care so much if it has physical beauty, because to me its real beauty is in how well, and how dependably, and how economically, and how ..., well you get it, it WORKS!
