Researchers from the University of California, Berkeley, told a stunned conference audience that they had managed to create a remote-controlled cyborg beetle by attaching a computer chip to the brain of a giant insect. Now, the paper explaining how they did it has been published in the journal Frontiers In Neuroscience, and they have released a video of the cyber-bug in action.
The cyborg beetle was designed as part of a DARPA project that looks to equip insects with cameras and other sensors in an attempt to turn them into tiny, biological UAVs. The rhinoceros beetle was selected because, as one of the world’s largest insects, it could carry the biggest payload.
The day of military-controlled, giant cyborg insects is upon us. Someone call Godzilla, I think we’re going to need some help.
The video below speaks for itself. Zombified with parts available at Radio Shack, the cyborg beetle flies around the room, controlled by a researcher at a laptop.
Insect control is not a new technology. A remote control system for cockroaches have been developed for years.
Much to the annoyance of home-owners everywhere, cockroaches are amazingly tough, and they’re able to squeeze into remarkably small spaces. These are some of the same qualities that researchers would like to see in tiny reconnaissance robots that could perform tasks such as searching earthquake-damaged buildings for survivors. Such adaptable, robust mini-robots would be quite challenging to create, however. A team of scientists from North Carolina State University are working on an alternative – sensor-equipped real cockroaches that are remotely controlled by human operators.
The project is being led by Alper Bozkurt, an assistant professor of electrical engineering. His team has fitted Madagascar hissing cockroaches with “backpacks” containing an inexpensive, lightweight, commercially-available chip, along with a wireless receiver and transmitter, and a microcontroller.
That microcontroller is wired into the cockroach’s antennae and cerci. Located in the abdomen, the cerci are sensory organs that detect air movement in order to warn of possible approaching predators. When the cerci are instead stimulated by the microcontroller, the result is the same as it would normally be – the cockroach thinks that something is coming at it from behind, and scuttles forward.
In order to direct that forward movement, either one of the antennae are stimulated. Ordinarily, they’re activated when they brush against unyielding objects, letting the cockroach know that it can’t move in that direction. In this case, when the stimulation comes not from an object but from a small electrical charge, the insect still reacts by changing course.
The microcontroller also monitors the interface between the cockroach’s tissue and the implanted electrodes that deliver the charges, in order to avoid neural damage.
While it still may be some time before cyborg roaches bearing tiny cameras or other devices possibly powered by implantable biofuel cells become commonplace, Bozkurt’s team has already successfully used the technology to guide cockroaches along curved lines on the floor. Some of the trials can be seen in the video below.
