STORY BELOW...

Miniature robots could be good spies, but researchers now are experimenting with insect cyborgs or "cybugs" that could work even better.

Scientists can already control the flight of real moths using implanted devices.

The military and spy world no doubt would love tiny, live camera-wielding versions of Predator drones that could fly undetected into places where no human could ever go to snoop on the enemy. Developing such robots has proven a challenge so far, with one major hurdle being inventing an energy source for the droids that is both low weight and high power. Still, evidence that such machines are possible is ample in nature in the form of insects, which convert biological energy into flight.

It makes sense to pattern robots after insects - after all, they must be doing something right, seeing as they are the most successful animals on the planet, comprising roughly 75 percent of all animal species known to humanity. Indeed, scientists have patterned robots after insects and other animals for decades - to mimic cockroach wall-crawling, for instance, or the grasshopper's leap.

Mechanical metamorphosis

Instead of attempting to create sophisticated robots that imitate the complexity in the insect form that required millions of years of evolution to achieve, scientists now essentially want to hijack bugs for use as robots.

Originally researchers sought to control insects by gluing machinery onto their backs, but such links were not always reliable. To overcome this hurdle, the Hybrid Insect Micro-Electro-Mechanical Systems (HI-MEMS) program is sponsoring research into surgically implanting microchips straight into insects as they grow, intertwining their nerves and muscles with circuitry that can then steer the critters. As expensive as these devices might be to manufacture and embed in the bugs, they could still prove cheaper than building miniature robots from scratch.

As these cyborgs heal from their surgery while they naturally metamorphose from one developmental stage to the next - for instance, from caterpillar to butterfly - the result would yield a more reliable connection between the devices and the insects, the thinking goes. The fact that insects are immobile during some of these stages - for instance, when they are metamorphosing in cocoons - means they can be manipulated far more easily than if they were actively wriggling, meaning that devices could be implanted with assembly-line routine, significantly lowering costs.

The HI-MEMS program at the U.S. Defense Advanced Research Projects Agency (DARPA) has to date invested $12 million into research since it began in 2006. It currently supports these cybug projects:

Roaches at Texas A&M.
Horned beetles at University of Michigan and the University of California at Berkeley.
Moths at an MIT-led team, and another moth project at the Boyce Thompson Institute for Plant Research.

Success with moths

So far researchers have successfully embedded MEMS into developing insects, and living adult insects have emerged with the embedded systems intact, a DARPA spokesperson told LiveScience. Researchers have also demonstrated that such devices can indeed control the flight of moths, albeit when they are tethered.

To power the devices, instead of relying on batteries, the hope is to convert the heat and mechanical energy the insect generates as it moves into electricity. The insects themselves could be optimized to generate electricity.

When the researchers can properly control the insects using the embedded devices, the cybugs might then enter the field, equipped with cameras, microphones and other sensors to help them spy on targets or sniff out explosives. Although insects do not always live very long in the wild, the cyborgs' lives could be prolonged by attaching devices that feed them.

The scientists are now working toward controlled, untethered flight, with the final goal being delivering the insect within 15 feet (5 m) of a specific target located 300 feet (100 meters) away, using electronic remote control by radio or GPS or both, standing still on arrival.

Although flying insects such as moths and dragonflies are of great interest, hopping and swimming insects could also be useful, too, DARPA noted. It's conceivable that eventually a swarm of cybugs could converge on targets by land, sea and air.

STORY BELOW

Cornell University researchers have succeeded in implanting electronic circuit probes into tobacco hornworms as early pupae. The hornworms pass through the chrysalis stage to mature into long-lived moths whose muscles can be controlled with the implanted electronics. The research was showcased at MEMS 2008, an international academic conference on Micro-Electrico-Mechanical Systems that took place from January 13-17 in Tucson, AZ.

The pupae insertion state was found to yield the best results. The resulting moth, a microsystem-controlled insect, has a circuit board protruding from the top of its midsection. Probes are inserted into the dorsoventral and dorsolongitudinal flight muscles. CT images show components of high absorbance indicating tissue growth around the probe.

The research also indicated the most favorable and least favorable times for insertion of control devices. The overall size of the circuit board is just 8x7mm, with a total weight of about 500 mg. The capacity of the battery is 16 mAh, and weighs 240 mg.

A driving voltage of 5 volts causes the tobacco hornworm blade muscles (two pairs) to move for flight and maneuvering.

The insect cyborgs are part of a program called HI-MEMS (Hybrid Insect MEMS), a DARPA program initiated by Program Manager Dr. Amit Lal. The ultimate goal of the HI-MEMS program is to provide insect cyborgs that can demonstrate controlled flight; the insects would be used in a variety of military and homeland security applications.

HI-MEMS program director Amit Lal credits science fiction writer Thomas Easton with the idea. Lal read Easton's 1990 novel Sparrowhawk, in which animals enlarged by genetic engineering (called Roachsters) were outfitted with implanted control systems.

Dr. Easton, a professor of science at Thomas College, sees a number of applications for HI-MEMS insects.

Moths are extraordinarily sensitive to sex attractants, so instead of giving bank robbers money treated with dye, they could use sex attractants instead. Then, a moth-based HI-MEMS could find the robber by following the scent."
"[Also,] with genetic engineering Darpa could replace the sex attractant receptor on the moth antennae with receptors for other things, like explosives, drugs or toxins," said Easton.

DARPA had better be careful with its insect army; in Easton's novel, hackers are able to gain control of genetically engineered animals by hacking the controller chips used in their implanted control structures.

If you are interested in one dark-side view of how this kind of invention could be used by corporations for advertising, see the madcap blurbflies from Jeff Noon's excellent 2000 sf novel Nymphomation.

They should use lightning bugs and strap a mini solar panel on its arse to power it

Cyborgs. Great...

It's like all these scientists watch the first 10 minutes of the science fiction movies where these ideas originated and say "Hey that's really cool, I'm gonna go work on making that real instead of watching the end of the movie and learning the moral of the story"
