Cyborg Cockroaches May Be Future Emergency Responders

Researchers say they've figured out a way to create cyborg, remote-controlled cockroaches, hoping one day the resilient creatures could be steered into disaster zones to gather information and look for survivors.
Video footage from the experiments at North Carolina State University shows the part-robot roaches being directed along a curving path via remote control. The researchers say they attached a lightweight chip with a wireless receiver and transmitter onto Madagascar hissing cockroaches and wired a microcontroller to the insects' antennae and cerci — the sensory organs on the bug's abdomen that cause it to run away from danger.
With electrical signals, the researchers stimulated the cerci to trick the roaches into thinking they needed to scamper away from a predator. Once moving, charges sent to the antennae controlled the insects' direction. A signal sent to one antenna could make a roach think its feeler was touching a wall, sending it in the opposite direction, a statement from NC State explained.
"Building small-scale robots that can perform in such uncertain, dynamic conditions is enormously difficult. We decided to use biobotic cockroaches in place of robots, as designing robots at that scale is very challenging, and cockroaches are experts at performing in such a hostile environment," NC State researcher Alper Bozkurt said in the statement.

"Ultimately, we think this will allow us to create a mobile web of smart sensors that uses cockroaches to collect and transmit information, such as finding survivors in a building that's been destroyed by an earthquake," Bozkurt added.
The researchers reported the results of their experiments late last month at the annual International Conference of the IEEE Engineering in Medicine & Biology Society in San Diego, Calif.
Other researchers have floated the possibility of technologically enhanced roaches. Scientists at Case Western Reserve University demonstrated how the insects could be outfitted with an implantable biofuel cell powered by a sugar the bugs make from their food. Electricity from such a cell then could be used to power sensors on the insect or to manipulate it by remote control.

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".
