Scientists at Northwestern University (PDF Connect) are working with sub-millimeter robots that are ready to “walk” without complex energy through pressure and various structures that will be difficult to operate on a limited scale until further notice.
This 8-footed crab (+2 arm) can walk sideways due to the uniquely made material. The invention works by creating legs that are reminiscent of their uniquely designed shapes. When heated with a laser, the legs change shape, allowing a movement to occur. Rehearse the cycle and you have “walking”.
The laser really controls how the robot moves and is a method of offloading a portion of the power source and mechanics from the robot. Depending on the material and the power of the laser, a few plans can really “bounce”, yet it runs at a moderate leisure.
This kind of innovation is a method in which small robots can move and it is well known in the nano-robot world. It is accepted that in the end, these gadgets will actually work in normally confined spaces, including the human body.
It has been speculated for some time that nanorobots will perform tasks at any time or any other method in a completely painless manner, for example, eradicating cancer or repairing tissue damage.
In sci-fi stories, you can “back up” your body condition and such machines can consistently restore it, making you successfully immortal. Fun, yet we shouldn’t lose track of the core problem at hand.
