In the field of robotics, innovations and developments are taking place constantly. Artificial intelligence (AI) is one of the most popular areas and has caught the fancy of not only scientists, but the common man as well. According to computer scientist, John McCarthy, "AI is the science and engineering of making intelligent machines, especially intelligent computer programs." A robot which has artificial intelligence can behave like a human being and learn from its surroundings, like the robot Baymax, in the movie, Big Hero 6. Here are some popular real-life robots that use AI.

WASHINGTON – Robotic systems and unmanned vehicles are playing an ever-growing role in the U.S. military -- but don't expect to see Terminator-style droids striding across the battlefield just yet. A top Pentagon official has given a tantalizing peek into several projects that not long ago were the stuff of science fiction, including missile-dodging satellites, self-flying F-16 fighters and robot naval fleets. Though the Pentagon is not planning to build devices that can kill without human input, Deputy Secretary of Defense Robert Work hinted that could change if enemies with fewer qualms create such machines. "We might be going up against a competitor that is more willing to delegate authority to machines than we are, and as that competition unfolds we will have to make decisions on how we best can compete," he said. Work, who helps lead Pentagon efforts to ensure the U.S. military keeps its technological edge, described several initiatives, including one dubbed "Loyal Wingman" that would see the Air Force convert an F-16 warplane into a semi-autonomous and unmanned fighter that flies alongside a manned F-35 jet.

Max Welling is a research chair in Machine Learning at the University of Amsterdam and has secondary appointments as full professor at the University of California Irvine and as a senior fellow at the Canadian Institute for Advanced Research (CIFAR). He is co-founder of "Scyfer BV" a university spin-off in deep learning. In the past he held postdoctoral positions at Caltech ('98-'00), UCL ('00-'01) and the U. Toronto ('01-'03). Max Welling has served as associate editor in chief of IEEE TPAMI from 2011-2015. He serves on the board of the NIPS foundation since 2015 and has been program chair and general chair of NIPS in 2013 and 2014, respectively.

Silicon Valley giants like Google, Amazon, Facebook, and Apple are investing more of their time and resources into artificial intelligence (AI) research in the hope that it will improve their existing products and lead to new ones. But they're far from the only ones aiming to create machines that can learn and think for themselves. A new generation of technology startups in Britain are focusing their efforts on developing products and services that are underpinned by AI, which has the potential to change the way we live our lives. Unfortunately, it also has the potential to end the human race if you listen to what billionaires like Elon Musk and intellects like Stephen Hawking have to say. Here are 10 of the most interesting British AI startups to watch out for in 2016.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

The usually sensible people at MIT's Senseable City Lab are looking at the future of the traffic light in the world of the self-driving car, and predict that its days are numbered. Instead, they propose a "slot-based intersections that could replace traditional traffic lights, significantly reducing delays, make traffic patterns more efficient, and lower fuel consumption." It's based on the principle that if all the self-driving cars are communication with each other and know they all are, they can plan speeds and courses so that they essentially pass through each other. Upon approaching an intersection, a vehicle automatically contacts a traffic management system to request access. Each self-driving vehicle is then assigned an individualized time or "slot" to enter the intersection.

Chat bots tap into two very current preoccupations. On one hand, the hope that they can actually work is a reflection of the ongoing explosion of AI, and on the other, they offer a way to reach users without having to get them to install an app. One way to look at any given AI problem, in the crudest terms, is to ask whether solving this needs'general AI' or whether your domain is narrow enough and your solution broad and flexible enough that you can deal with a wide enough percentage of potential scenarios without having HAL 9000. That is, we're clearly pretty close to making a car that can handle highway driving with no human input, since the range of possible events is pretty small, but driving in central Rome or Moscow is an entirely different matter that needs an entirely different level of decision-making: what does that hand gesture mean? Hence, the challenge in plugging an AI into a'conversational' chat bot interface is that you don't have HAL 9000 but are in some sense pretending to the user that you do.

It's been an emotional week in the realm of game AI as the world watched the historic five-game showdown between legendary Go world champion Lee Sedol and Google DeepMind's famed deep learning AI AlphaGo. All five games were held at the Four Seasons Hotel in Seoul, South Korea, and as events played out, millions around the world became increasingly captivated. Anticipation for the match began growing in January, when Google's UK-based AI group DeepMind, led by CEO Demis Hassabis, announced their computer algorithm AlphaGo defeated three-time European Go champion Fan Hui 5 games to 0--a victory some experts didn't expect a computer to achieve for a decade. At the end of a Google blog post announcing the win was the promise of a best-of-five face-off between AlphaGo and 18-time international Go champion Lee Sedol, a match equivalent to IBM's Deep Blue defeat of Garry Kasparov in chess in 1997. Notably, Go is inherently more complex than chess and AlphaGo, at least in part, trained itself to play the game.

Not quite yet: Factory 2050 in Sheffield, UK, isn't building anything you can buy. Instead, the brains behind the project are rethinking the manufacturing process itself, aiming to change how we make everything from airplanes to nuclear power plants. Inside the factory, things are looking a little unfinished. It opened in January, and the team from the University of Sheffield's Advanced Manufacturing Research Centre (AMRC) are still moving in. The place is sparkling clean, and smells like a newly furnished IKEA, but it's gearing up to change the way whole industries work by applying virtual reality, robotics and bitcoin's blockchain.
