Intelligent Autonomous Flying Robots Learn and Map Environment As They Fly
An anonymous reader writes with this story about a machine-learning project out of the UK's University of Sheffield: Using simple drones the researchers have created automatic-control software that enables the "flying robot" to learn about its surroundings using a camera and an array of sensors. The robot starts with no information about its environment and the objects within it. But by overlaying different frames from the camera and selecting key reference points within the scene, it builds up a 3D map of the world around it. Other sensors pick up barometric and ultrasonic data, which give the robot additional clues about its environment. All this information is fed into autopilot software to allow the robot to navigate safely, but also to learn about the objects nearby and navigate to specific items.
This is pretty important given the biblical version of the end times. A hole in the ground opens up and from the underground comes small golden flying things to seek out man and sting him. Sounds like small drones to me, but i thought not in my lifetime as they need an operator to control them and software for self flying self control self knowledge doesnt exits and likely wont in my lifetime, but here we have self learning self flying self targeting activated software. There goes my rational for the rapture not being in my lifetime. Geez and to think the end may come in my lifetime, so fast from zero to total control by the beast power.
It would be nice if these were fed back in real time to a remote monitor. Maybe a 21st century canary in a coal mine? Applications for search and rescue, scouting real time optimal traffic routes for police / fire / paramedics.
Cool project, but the article/video is short on detail. I'd like to know more about the way this robot is actually learning. Is it a neural network? How does it know an oscilloscope is an oscilloscope? Does it use binocular vision to recognize distance? Ultrasound? Both? What type of computing hardware is on board? For that matter, what type of quadracoptor is this? And more importantly where can I get one?

Carnegie Mellon folks developed the SLAMM algorithm (and variants of if) some years back to do live mapping on their quadrotors. It has been used by almost everybody who is doing autonomous flying robots. It is hard not to say that anyone was not influenced by that work. Some of their work had laser scanners that would map the surroundings and identify walls -- building out a maze of sorts as it explored. Heck on seeedstudio.com you can pickup a (LIDAR) 360 2D laser scanner and algorithm to build your own.
Not taking anything away from the English (as what they have done is pretty impressive and a different approach), though am curious how it is different algorithm wise?
One of the research avenues I think at some point will be to have mesh networking on these robots to share info so that in a hostile/harsh environment as these things get damaged the mapping data is passed along for fire crews, soldiers, HAZMAT, etc.
Eh, it's just a roomba in three dimensions.
Doing this is called Simultaneous Localization and Mapping, or SLAM. There's been enormous progress in that in the last decade. The basic idea is to take a large number of images of the same scene, possibly with inacccurate data about where they were taken, and build up a 3D model. It sort of works most of the time. Some algorithms do well indoors, especially where there are lots of strong edges and corners. Those are easy features to lock onto. Outdoors is tougher, although outdoors you can usually use GPS. It's a basic capabiilty robots need.
The video is frustrating. There's no comparison with previous work. Is this an advance, or did they just use known algorithms.
They tend to bump into the same walls repeatedly before learning they're there and proceeding to bump into the adjacent wall.

So the robot starts with no information about its environment and the objects within it. By overlaying different frames from the camera and selecting key reference points within the scene, it builds up the 3D map of the world around it. Barometric and ultrasonic sensors give the robot additional clues about its environment. All this information is fed into autopilot software to allow the robot to navigate safely, but also to learn about the objects nearby and navigate to specific items.
Instead of a neural network, the researchers used just basic game theory to program the quadrocopters. In this framework, each robot is a player in the game and must complete its given task in order to "win" the game. If the robots "play the game" repeatedly they start to learn each other’s behavior. They can then perform their task successfully – in this case getting past the other robot – by using previous experience to estimate the behavior of the other robot.
As to your question about where to get one of these, this is just a research project. It would require a lot of more hard work, some Asian manufacturing arrangements, a global supply chain, and an investor to make this a product. Maybe some day.
The more intelligent and autonomous my flying robots are, the better, I say ... hey, what are you ... Gahhhhhhhhh!!!
This is how the "PUPS" the geologist in Prometheus used to map the cave (and the engineers ship).
So Ridley Scott just stole this idea from SLAM or the Sheffield university!!!!!!!!!!
They are using PTAM package from Uni of Oxford

Whats more they are using off the shelf ardrone-PTAM package

and replicating something done TWO YEARS AGO by Jens Nyman (from Belgian uni)

Welcome to 1990, where we can share a project like this on a thing called the 'internet'.
Welcome to 2000. We can share the software on this thing called the 'internet'. Quad copters are a dime a dozen.
Notice that this is not only locartion and mapping but also object recognition.
