Lockheed Martin's Spybot Knows How Not to Be Seen

This stealthy robot from Lockheed Martin is smart enough to know when you can see it and when you can't, and picks all the right hiding places

Lockheed Martin's Spybot Knows How Not to Be Seen

There are some basic rules that both humans and robots should be aware of when it comes to not being seen, and Monty Python only scratched blew up the surface. Lockheed Martin's Advanced Technology Laboratory has been developing a robot designed to operate around humans without being detected, and not just by being small and quiet: it listens for humans, guesses where they might be looking, and then finds itself a nice dark hiding place when it needs to.

Lockheed's robot is equipped with a 3D laser scanner that allows it to build detailed maps of its surroundings. It also has an array of acoustic sensors, which allow it to localize footsteps and voices. It can then combine the locations of humans with its 3D map to guess what areas the humans might be able to see, and then does its best to stay hidden. Keeping to the shadows, the robot always maintains an escape route, and if it senses a human approaching, it will look for the deepest darkest corner it can find and then hold its virtual breath until the danger has passed.

This is certainly not the first deceptive robot we've seen. Given the opportunity, a robot swarm at EPFL independently evolved the capacity for deception alarmingly quickly in a competition for virtual food. And researchers from Georgia Tech taught a robot to use deliberately deceptive tactics to fool other robots and humans. The Georgia Tech research, especially, seems like it's destined for applications like surveillance, as it endows a robot with a method of analyzing a situation to determine whether deception would be effective, based on what it knows about the robot (or person) trying to find it. If it decides that deception would help it achieve its goals, the robot then leaves tracks in one direction before moving off in a different one.

The key to avoiding detection by humans is to understand how you're perceived by humans. As Monty Python so astutely pointed out, for example, even the most perfect hiding place won't do you any good if it's the only possible place that you can be. By building models of both physical environments and perceptual environments, or how humans sense and react to things, robots will be much better at not just spying, but also understanding and reacting to us in less adversarial environments.

Russia is the world's largest wheat exporter, with 20 percent of the world's wheat trade. Combine harvesters that can drive themselves using technology from Russian company Cognitive Pilot are helping to make the harvesting process faster and more efficient.

The field of automated precision agriculture is based on one concept—autonomous driving technologies that guide vehicles through GPS navigation. Fifteen years ago, when high-accuracy GPS became available for civilian use, farmers thought things would be simple: Put a GPS receiver station at the edge of the field, configure a route for a tractor or a combine harvester, and off you go, dear robot!

Practice has shown, however, that this kind of carefree field cultivation is inefficient and dangerous. It works only in ideal fields, which are almost never encountered in real life. If there's a log or a rock in the field, or a couple of village paramours dozing in the rye under the sun, the tractor will run right over them. And not all countries have reliable satellite coverage—in agricultural markets like Kazakhstan, coverage can be unstable. This is why, if you want safe and efficient farming, you need to equip your vehicle with sensors and an artificial intelligence that can see and understand its surroundings instead of blindly following GPS navigation instructions.
