Killer Robotic Insects

Chased by robotic bees: Film Still from 'Hated in the Nation' Black Mirror Series

On November 12, 2017,  a video called “Slaughterbots” was uploaded to YouTube. … It is set in a near-future in which small drones fitted with face-recognition systems and shaped explosive charges can be programmed to seek out and kill known individuals or classes of individuals (those wearing a particular uniform, for example). In one scene, the drones are shown collaborating with each other to gain entrance to a building. One acts as a petard, blasting through a wall to grant access to the others…

[M]ilitary laboratories around the planet are busy developing small, autonomous robots for use in warfare, both conventional and unconventional. In America, in particular, a programme called MAST (Micro Autonomous Systems and Technology), which has been run by the US Army Research Laboratory in Maryland, is wrapping up this month after ten successful years….. Its successor, the Distributed and Collaborative Intelligent Systems and Technology (DCIST) programme, which began earlier this year, is now getting into its stride….Along with flying drones, MAST’s researchers have been developing pocket-sized battlefield scouts that can hop or crawl ahead of soldiers. DCIST’s purpose is to take these autonomous robots and make them co-operate. The result, if the project succeeds, will be swarms of devices that can take co-ordinated action to achieve a joint goal.

If swarms of small robots can be made to collaborate autonomously, someone, somewhere will do it…[Many of these small robots are today] cyclocopters …of less than 30 grams. Such machines can outperform polycopters...Cyclocopter aerodynamics is more like that of insects than of conventional aircraft…Cyclocopters get better as they get smaller. They are also quieter…[Another innovation involves] robots…that hop.One of the most advanced is Salto, developed by the Biomimetic Millisystems Laboratory at the University of California, Berkeley. Salto… has the agility to bounce over uneven surfaces and also to climb staircases…

Bouncing over the rubble of a collapsed building is not the only way to explore it. Another is to weave through the spaces between the debris. Researchers at the Biomimetic Millisystems lab are working on that, too. Their solution resembles a cockroach.

Getting into a building, whether collapsed or intact, is one thing. Navigating around it without human assistance is quite another. For this purpose MAST has been feeding its results to the Defence Advanced Research Projects Agency (DARPA)… The next challenge…is getting the robots to swarm and co-ordinate their behavior effectively.
