Joe Gordon likes to climb mountains. Among his conquests is Mount Teide, a 12,000ft volcano in Tenerife. "I like to walk up hills and mountains," he says. "I am a big fan of a healthy body and a healthy mind." It is perhaps just as well that he has a head for heights.

It's called the prisoner's dilemma and it goes like this: You and a fellow gang member are in jail. One of you committed a heinous crime, but the prosecutor doesn't know who. Instead, you are both booked on a lesser charge and serving a one-year sentence in solitary confinement. But here's the deal: The prosecutor has given you both an opportunity to rat. If you betray your fellow gang member but are not ratted on, you walk free while your buddy serves a three-year term.

This paper presents a novel approach for localising a GPS (Global Positioning System)-denied Unmanned Aerial Vehicle (UAV) with the aid of a GPS-equipped UAV in three-dimensional space. The GPS-equipped UAV makes discrete-time broadcasts of its global coordinates. The GPS-denied UAV simultaneously receives the broadcast and takes direction of arrival (DOA) measurements towards the origin of the broadcast in its local coordinate frame (obtained via an inertial navigation system (INS)). The aim is to determine the difference between the local and global frames, described by a rotation and a translation. In the noiseless case, global coordinates were recovered exactly by solving a system of linear equations. When DOA measurements are contaminated with noise, rank relaxed semidefinite programming (SDP) and the Orthogonal Procrustes algorithm are employed. Simulations are provided and factors affecting accuracy, such as noise levels and number of measurements, are explored.

When science fiction author Isaac Asimov devised his Three Laws of Robotics he was thinking about androids. He envisioned a world where these human-like robots would act like servants and would need a set of programming rules to prevent them from causing harm. But in the 75 years since the publication of the first story to feature his ethical guidelines, there have been significant technological advancements. Sci-fi author Isaac Asimov devised his Three Laws of Robotics he was thinking about androids. The three'Laws of Robotics' were devised by sci-fi author Isaac Asimov in a short story he wrote in 1942, called'Runaround'.

A lot of us have been looking at the recent WikiLeaks drop of Central Intelligence Agency (CIA) files related to hacking Internet of Things (IoT) and personal technology devices. It includes a lot of data, so it is easy to get lost in the woods with regard to what these tools do. But apparently they can break into devices and cast blame for it on the Russians, which I believe is problematic in a whole number of different ways. I think the real problem with this is the CIA's risk assessment process. I think this decision process problem is far larger than just the CIA and reflects on security in general. I also think that a deep learning tool like IBM's Watson could, if placed in the decision process, help prevent bad decisions like this.

Video Friday is your weekly selection of awesome robotics videos, collected by your Automaton bloggers. We'll also be posting a weekly calendar of upcoming robotics events for the next two months; here's what we have so far (send us your events!): Let us know if you have suggestions for next week, and enjoy today's videos. The winner of the best video competition at HRI 2017 was this masterpiece from Professor Hiroshi Ishiguro (aka "The Man Who Made a Copy of Himself") and colleagues Dylan F. Glas, Malcolm Doering, Phoebe Liu, and Takayuki Kanda from the Advanced Telecommunications Research Institute in Kyoto: Stay tuned for the live concert tour, and read the paper at the link below. Dreamer's disembodied head can follow you without blinking.

Last month, when President Donald Trump toured a Boeing aircraft plant in North Charleston, South Carolina, he saw a familiar face in the crowd that greeted him: Patrick Caddell, a former Democratic political operative and pollster who, for forty-five years, has been prodding insurgent Presidential candidates to attack the Washington establishment. Caddell, who lives in Charleston, is perhaps best known for helping Jimmy Carter win the 1976 Presidential race. He is also remembered for having collaborated with his friend Warren Beatty on the 1998 satire "Bulworth." In that film, a kamikaze candidate abandons the usual talking points and excoriates both the major political parties and the media; voters love his unconventionality, and he becomes improbably popular. If the plot sounds familiar, there's a reason: in recent years, Caddell has offered political advice to Trump. He has not worked directly for the President, but at least as far back as 2013 he has been a contractor for one of ...

A page from the notebook of British mathematician and pioneer in computer science Alan Turing, the World War II code-breaking genius, is displayed in front of his portrait during an auction preview in Hong Kong Thursday, March 19, 2015. This week's milestones in the history of technology include Alan Turing anticipating today's deep learning by intelligent machines and concerns about the impact of AI on jobs, Clifford Stoll anticipating Mark Zuckerberg, and establishing the FCC and NPR. Alan Turing gives a talk at the London Mathematical Society in which he declares that "what we want is a machine that can learn from experience." Anticipating today's enthusiasm about machine learning and deep learning, Alan Turing described how intelligent machines will work: Let us suppose we have set up a machine with certain initial instruction tables, so constructed that these tables might on occasion, if good reason arose, modify those tables. One can imagine that after the machine had been operating for some time, the instructions would have altered out of all recognition, but nevertheless still be such that one would have to admit that the machine was still doing very worthwhile calculations.

For years, Facebook has been investing in artificial intelligence fields like machine learning and deep neural nets to build its core business--selling you things better than anyone else in the world. But earlier this month, the company began turning some of those AI tools to a more noble goal: stopping people from taking their own lives. But it's not just tech giants like Facebook, Instagram, and China's up-and-coming video platform Live.me who are devoting R&D to flagging self-harm. Doctors at research hospitals and even the US Department of Veterans Affairs are piloting new, AI-driven suicide-prevention platforms that capture more data than ever before. The goal: build predictive models to tailor interventions earlier.

Kolkata, March 18 (IANS) An artificial intelligence-enabled app launched by the West Bengal government lets commuters know about the real-time location of over 700 state-run buses and other related information, an official said on Friday. According to Rachpal Singh, Chairman of West Bengal Transport Corporation, the app called "Patha Disha" once downloaded on one's phone can inform on availability of seats and specific buses and estimated time of arrival at the destination. It even provides data on how crowded the bus is. "The app was launched in sync with the prepaid electronic transport card. The real-time tracking services and prepaid system will be extended to trams and waterway transit services as well," Singh said.
