Cyborg Insect Spies




Originally appeared: February 13, 2009

 What if the Pentagon implanted devices called micro-electrical mechanical systems, or MEMS, in insects to create swarms of tiny, remote-controlled cyborg secret agents, capable of flying or crawling into enemy territory to gather intelligence in places too well-guarded or dangerous for human spies?
Half-bugs, half machines could conduct surreptitious video and audio surveillance and carrying sensors to detect radioactivity or chemicals. But why stop there?

Just as U.S. Predator drone aircraft have been equipped with missiles, it’s conceivable that insect cyborgs could be equipped with tiny but potent weapons, such as poison or hallucinogenic drugs, that they could use to attack high-value targets, such as a terrorist leader or a dictatorship’s key nuclear weapons scientist.

Utilizing insect cyborgs for intelligence-gathering and covert operations would have some enormous potential advantages. There’s a vast talent pool of potential recruits, since the planet’s insect population includes at least one million species that we know about, plus perhaps an even greater number that are yet to be discovered. And unlike James Bond, they’d work for cheap. Detecting miniscule secret operatives would be exceedingly difficult, and existing countermeasures against insects, such as bug zappers or insecticides, aren’t really all that effective, as anybody who’s been eaten alive by mosquitoes at a summer bar-b-q knows too well. 

The potential downside, though, might make you reach for your flyswatter. We could risk launching an insect arms race with Russia and China, and who knows where that might lead. A malevolent president could just as easily deploy insect cyborgs against homegrown political dissidents. (Some even suspect this already has happened, as this 2007 Washington Post article details.) And finally, the conscription of unwilling insects for military purposes is sure to be objected to by the nascent insect rights movement.

And no, I didn’t get this idea from the Onion,  as hoaxical as it might seem. (Rank me slightly higher on the skepticism scale than, say, a certain unnamed Chinese newspaper editor, who once lifted an Onion story about the U.S. Congress demanding a new Capitol building and reprinted it as fact.) To the contrary, I got it from the web site of the Defense Advanced Research Projects Agency, which actually is attempting to develop a MEMS capacity for insects.
Here’s a description  of DARPA’s Hybrid Insect MEMS project, which is being led by electrical engineer and computer scientist Amit Lal :
    The HI-MEMS program is aimed at developing tightly coupled machine-insect interfaces by placing micro-mechanical systems inside the insects during the early stages of metamorphosis. These early stages include the caterpillar and the pupae stages. Since a majority of the tissue development in insects occurs in the later stages of metamorphosis, the renewed tissue growth around the MEMS will tend to heal, and form a reliable and stable tissue-machine interface. The goal of the MEMS, inside the insects, will be to control the locomotion by obtaining motion trajectories either from GPS coordinates, or using RF, optical, ultrasonic signals based remote control. The control of locomotion will be investigated using several approaches. These include direct electrical muscle excitation, electrical stimulation of neurons, projection of ultrasonic pulses simulating bats, projection of pheromones, electromechanical stimulation of insect sensory cells, and presentation of optical cues with micro-optical visual presentation. The intimate control of insects with embedded microsystems will enable insect cyborgs, which could carry one or more sensors, such as a microphone or a gas sensor, to relay back information gathered from the target destination.
Here’s more:
HI-MEMS derived technologies will enable many robotic capabilities at low cost, impacting the development of future autonomous defense systems. The realization of cyborgs with most of the machine component inside the insect body will provide stealthy robots that use muscle actuators which have been developed over millions of years of evolution. The basic technology developed in this program could also be used as a biological tool to understand and control insect development opening vistas in our understanding of tissue development, and provide new technological pathways to harness the natural sensors and power generation from insects.
As usual, this idea has been lurking around for years. Back in 1990, Tom Easton, a science professor at Thomas College in Maine, wrote a science fiction novel, Sparrowhawk, in which he envisioned the implanting of computer chips in insects and other animals.
In the early 2000s, researchers at the State University of New York and the University of Florida used brain implants to create remote-controlled rats whose movements and olfactory instincts could be controlled wirelessly from a distance. Since then, according to news reports, DARPA has developed the ability to implant devices into moth pupae and have created cyborg beetles whose muscles generate the electricity to power instruments.
In late January, the Japanese web site Tech On! that at a conference in Italy, DARPA-funded University of California, Berkeley scientists showed a video of a radio-controlled rhinoceros beetle.
Researchers at the university controlled the movement of beetle wings and some other parts using radio signals sent to the six electrodes on its brain and muscles. They equipped the beetle with a module incorporating a circuit to send signals to the electrodes, wireless circuit, micro-controller and battery. The university has so far succeeded in several experiments of electrically controlling insects, but it used a radio control system this time.

The researchers used rhinoceros beetles in this experiment because they can carry a weight of up to 3g. They can fly carrying the module weighing about 1.3g on their backs. And another reason is that they look cool, according to the university.
So we know that it’s possible. But should the government go ahead and create an ant-farm version of the CIA? Express your opinion below.
