Do you smell a rat? Well, it just may be that the rats around this place were recently oiled.
Such a conversation could be in our futures now the scientists are trying to develop robotic rats for dangerous missions like rescue operations and deep space exploration. Why does the world need robotic rats? The answer is in the whiskers.
From TFOT (The Future of Things):
Scientists from Europe, Israel, and the USA are developing 'robotic rats' that will be able to aid in rescue operations and carry out planetary research missions. Nine research groups from seven countries are collaborating on this initiative, which was recently set up with the aim of imitating nature.
Active sensing is widely common in the animal kingdom. For example, rats’ whiskers function as active sensors. A multinational team was recently assembled in order to develop a series of innovative tactile technologies, including a 'whiskered' robotic rat, which will be capable of quickly locating, identifying and capturing moving objects. "The use of touch in the design of artificial intelligence systems has been largely overlooked, until now," says Professor Ehud Ahissar of the Weizmann Institute of Science’s Neurobiology Department, who is taking part in the project.

Why is the sense of touch in a rat’s whiskers so much more efficient than that of the average person’s finger tips? The consortium’s teams have managed to provide some answers to this question. One of the explanations relates to the way in which the sensory system works; whiskers actively sweep back and forth repetitively, accumulating information about their surroundings. The sensing begins in the neurons at the whiskers’ bases, which ‘fire’ signals to the brain. Further experiments have shown that the way in which a rat uses its whiskers is context-dependent. For example, the seemingly simple act of feeling out a 3-D object requires three different types of code, each encoding a different dimension and calculating the horizontal, the vertical, and the radial distance of the object from the whisker base.
TFOT has some great links to the world of robotics... if I do say so by the hair of my chinny chin chin. Oh, that's right I shaved it off.
