Há um óptimo artigo que descreve com bom pormenor o funcionamento do sistema da Google para os carros autónomos. Por um lado é uma coisa brilhante, por outro replicar em larga escala vai necessitar da obtenção de um volume gigante de informação que ainda não existe. E essa informação terá que ser renovada sistematicamente (aqui penso que a forma mais fácil será equipar os próprios carros autónomos, quando forem vendidos, com a capacidade de captação dessa informação e envio para um sistema central).

Em todo o caso abre-se a hipótese de aproximações alternativas menos dependentes de um repositório tão gigantesco de dados sobre as zonas que atravessam.

Ainda não vi como é que o sistema da Delphi funciona. Uma vez vi uma referência à Google misturada com a Delphi o que achei estranho.

agora não me lembro onde vi escrito, mas uma ideia futura será estes carrinhos interagirem uns com os outros e com os sinais luminosos, de forma a formarem swarms segundo o destino que levam. coladinhos uns aos outros, à mesma velocidade. é uma optimização fantástica do tráfego citadino.

L

Os carros autónomos vão conseguir fazer isso MESMO sem comunicação entre eles, da mesma forma que um bando de pássaros ou um cardume de peixes não precisa de comunicar para não se espalharem uns contra os outros. A dificuldade, claro, está em que isso só é razoavelmente possível sem condutores humanos no mix. Mas ainda assim o tempo de reacção de um carro às alterações de velocidade e rumo de outros vai ser fantasticamente pequeno.

Watch Atlas go through a push test before DARPA's Robotics Challenge

The DARPA Robotics Challenge finals is scheduled for June 5th to 6th, and we'll bet the finalists are now pulling all-nighters finishing up their entries. Team IHMC Robotics from the Institute of Human and Machine Cognition in Pensacola, for instance, is working to further improve its Atlas-based machine called Running Man. In the video below the fold, you'll see the team demonstrate its fall avoidance and push recovery technique. If you recall, DARPA's contest is specifically looking for humanoid machines for disaster relief and search-and-rescue operations. We've got a feeling those types of robots won't be operating under the best conditions, so the ability to withstand outside forces will surely come in handy.

Não sendo os computadores, os robots, inteligências naturais, biológicas, como podem elas equipararem-se a nós, que intuímos o pensamento uns dos outros, somos afectados fina, subtil ou fatalmente por acontecimentos externos do mundo em que estamos imersos; sentimos e pensamos com urgência e aflição nos males que receamos, deleitamo-nos com os prazeres que vamos acedendo ou simplesmente esperamos alcançar! Quanta dissemelhança nos separa dos robots, pedaços de ligações sem vida, sem desejos nem afectos, sem valores, sem ódios, sem rumo natural no meio do mundo! Como dizia o The Economist desta semana: «perguntar se um computador pode pensar é como perguntar se os submarinos podem nadar.»! :)

Uber gutted Carnegie Mellon’s top robotics lab to build self-driving cars
A 'partnership' based on poaching

This January, as much of the world was getting over its post-holiday hangovers, people began disappearing from Carnegie Mellon University's robotics center. At first it was only a few individuals, mostly software developers. Then it became an entire team, and eventually the group included the center's director.

They weren't going far.

Just around the corner, Uber had set up shop in a renovated building that used to be a chocolate factory. Most people at CMU's National Robotics Engineering Center (NREC) didn't even know it yet, but in a building that shared the very same parking lot, the ride-hailing company had embarked on a multi-year project to replace human drivers with computers. And to do that, they'd need all the help they could get. So Uber got to work snapping up some of the company's most talented staffers.

"THESE GUYS, THEY TOOK EVERYBODY."

"They took all the guys that were working on vehicle autonomy — basically whole groups, whole teams of developers, commercialization specialists, all the guys that find grants and who were bringing the intellectual property," recalls a person who was there during the departures. "These guys, they took everybody."

All told, Uber snatched up about 50 people from Carnegie Mellon, including many from its highest ranks. That's an unusually high number of people to leave at once, and accounted for about a third of the staff NREC had at the end of last year. Many were top employees, including David Stager, who had been there since 1997 and is now Uber's lead systems engineer; Jean-Sébastien Valois, a senior commercialization specialist who had been with NREC for nearly 12 years (and lists himself as "on leave" on CMU's site); and Anthony Stentz, NREC's director for the past four and a half years, who had been at the center since 1997. News of some of the departures was reported earlier this year by TechCrunch and The Pittsburgh Business Times.

In February, Uber and CMU went public with what the pair called a strategic partnership, announcing a grand vision to make joint advances in research and development for maps, vehicle safety, and autonomous driving. "This is yet another case where collaboration between the city and its universities is creating opportunities for job growth and community development," Pittsburgh Mayor William Peduto said at the time. Uber and CMU promised to hold an event to go into more detail on the partnership in the city a few weeks later, but no event ever materialized.

UBER IS MOVING INTO NEW DIGS

Now, four months later, Uber is making its first move. Yesterday the company announced plans to lease a 53,000 square foot facility that used to be a Restaurant Depot supply store. The space, which is about a mile down the road from NREC and Uber's current digs, will be transformed into the company's new Advanced Technologies Center by the end of this year — presumably with some of the fanfare that was promised back in February.

In the meantime, it's not clear exactly what Uber is up to, or who is working on what inside of NREC's walls. Part of the deal includes a "transition period" that keeps some of the departed staffers around, but only to wrap up odds and ends of existing projects. The unusual arrangement has bothered some employees at NREC who say it's created tensions among staff and their former colleagues.

"The work of these employees is very incestuous and loose," says the same NREC insider. "They are given free rein of the facilities as part-time CMU employees, but there are absolutely no checks on the work that they are doing or what [intellectual property] they are taking. Is it for CMU? Is it for Uber? None of us here know."

CMU officials declined multiple requests for comment, referring only to a statement made by Andrew Moore, the dean of its School of Computer Science back in February, praising the partnership. "We look forward to partnering with Uber as they build out the Advanced Technologies Center and to working together on real-world applications, which offer very interesting new challenges at the intersections of technology, mobility and human interactions," Moore said at the time.

In a statement, Uber said only that it looks forward to the partnership with CMU, and moving into its new space:

We’ve been focused on finding a space for Uber’s Advanced Technologies Center and recently leased a new space in Pittsburgh. We expect to move in at the end of the year and will be moving forward with plans to hold an event. We look forward to continuing to build our partnership and work closely with the CMU team.
Shortly after the original announcement, Martial Hebert, the director of CMU's Robotics Institute acknowledged these ongoing wrap-up projects to The Pittsburgh Business Times, but stressed that the partnership would be a good thing for everyone in the long term. "The way I see the story is that there is a slightly negative part, which is the fact that we have to reorganize certain things, but there is a hugely important side, which is that this Uber center is just the tip of the iceberg," Hebert said. "It's an indication that robotics as an industry, as a field, has now matured."

NREC PROJECTS RANGE FROM COMBAT VEHICLES TO SORTING STRAWBERRIES

Yet, the lack of clarity and sudden absence of talented colleagues presents new challenges for NREC, a nearly 20-year-old institution that has designed everything from uncrewed ground combat vehicles to an automated system for sorting strawberries on commercial farms. Most of these projects come from external clients, which include commercial companies, NASA, and the military. The clients pay for the research, and both sides end up with a proof of concept that can be made into a commercial product or licensed to others. Unlike a commercial enterprise, though, what ends up being invented at NREC is not mass-produced there.

Uber, on the other hand, has mass production squarely in its sights. The entire premise of this partnership is so that Uber can be ahead of the curve with autonomous driving and the technologies surrounding it. At the end of 2014, Uber had 160,000 drivers around the world on its platform — jobs that can and likely will be replaced by self-driving systems in the next few decades. There are expected to be safety benefits to eliminating human drivers, but it could also radically improve Uber's business by eliminating its top expense.

 
Google's upcoming self-driving car. (Google) ANYONE WHO IS ANYONE IS WORKING ON A SELF-DRIVING CAR
The competition to get self-driving cars onto roads is getting more heated all the time. Google (whose self-driving car director, Chris Urmson, is himself a CMU robotics alum) is working to have its own driverless car ready by 2020. Tesla is on the verge of launching an "autopilot" feature that lets its sedans drive themselves on highways, as well as self-park when people find their way back to the garage. The electric car maker is trying to automate all the other parts of driving, something that still requires years of research and changes in local and federal regulations.

CMU was a natural choice for Uber to pick as its partner: the university has an impressive track record in designing automated vehicles. In 2004, when DARPA held its first Grand Challenge — a contest to put autonomous vehicles to the test — the CMU team made it the furthest. Its vehicle, an ‘86 Humvee named Sandstorm, made it 7.4 miles of the competition's 150-mile-long course. It didn't win the $1 million bounty, but it firmly established CMU as a leader in its field. At the following year's contest, two CMU vehicles came in second and third place, respectively, losing to Stanford by a few seconds. Two years later, CMU returned the favor, beating Stanford in DARPA's Urban Challenge, which brought the cars to cities for the first time. Since then, when VIPs like the president or the US secretary of transportation come by for visits at NREC, the cars are still trotted out as badges of honor, a testament to the technologies that have been created under its roof.

YOU CAN'T BUY A UNIVERSITY, BUT YOU CAN MAKE ITS EMPLOYEES BETTER OFFERS

One likely driving factor in NREC departures is money. Uber is flush with it, with recent reports suggesting the company is raising another $1.5 billion in funding, valuing the company at $50 billion. As part of this deal, Uber paid CMU an undisclosed sum to fund faculty chairs and graduate fellowships. CMU declined to comment on its partnership with Uber, including questions about how much money changed hands and who owned the resulting technologies.

Looking ahead, greater questions linger about what will happen at NREC without some of these people there. A key part of attracting new projects has been proving that they can be turned into something commercially viable. Historically, the people responsible for that were the commercialization specialists. If you were to think of NREC like a law firm, these people are like the partners, and are the ones who are actually developing things and helping get them off the ground. Six of the eight commercialization specialists NREC currently has listed on its site all left for Uber, while a seventh — Dr. Herman Herman — was named the group's new director in March.

Other ramifications of the departures at NREC may end up being more immediate. There's lingering resentment from some of the people involved on these projects who were not picked to come over to Uber. Shortly after the departure, there were also murmurings of moving everyone to a smaller space given that it was harder to justify a building that spanned 100,000 square feet and three entire blocks. Instead, the company is in the midst of trying to rearrange its existing workspaces given the newfound emptiness.

For Uber, though, this all seems like another footnote in the company's quest to get somewhere better and faster than its rivals can. Poaching an entire team may not even be the most dramatic business move it makes this year. But the company has definitely left its mark in Pittsburgh.

Future potential of brain chip is limitless after man controls robot arm with his thoughts

Ian Burkhart’s hand moves for the first time since his paralyzing accident four years ago, during a training session in Columbus, OH on June 18, 2014. It gained motion with the help of a chip implanted in Burkhart’s brain, a computer and electrodes wrapped around his arm. Burkhart even picked up an ice cream scoop. (Photo by Lee Powell / The Washington Post)

Scientists at Caltech reported Thursday that they had developed an implantable chip that gave a tetraplegic man, Erik G. Sorto, the power to drink beer with a robot arm. This is just the beginning.

Researchers are working on all manner of silicon-based devices that go inside the body and manipulate the body’s signals to create motion. They believe these chips will not only be able to help those with paralysis one day -- but also usher in a new era of robot adjuncts controlled by someone’s thoughts that will be able to perform all manner of jobs from lifting dangerous objects to filing papers.

Here’s a look at some of the other promising research:

A group in Lausanne, Switzerland announced in January that they had helped mice with near-severed spines walk again with a ribbon of stretchable silicon that is placed under the nerve tissue. They used the gadget to second electrical signals through the animals as well as to deliver chemicals for nerve impulse transmission. In six weeks, the mice could not only walk but run and climb stairs again. Scientific American likened the technique to fixing a cuts in a telephone cable.

Signals that start in the brain are supposed to travel down nerves in the spinal cord to muscles, but breaks in the nerves interrupt them. Patching the breaks with new wires, jumping over the cut in the phone line, should restore communication.

In Ohio last year, doctors operated on a 22-year-old man to insert a chip into his brain that is connected to a port leading to a cable that is plugged into a computer programmed to decode messages from the brain. According to a report in The Washington Post, here’s how it would work:

The electrodes were designed to pulse and stimulate muscle fibers so that the muscles could pull on tendons in his hand.

If it all worked, a man who was paralyzed from the chest down would think about wiggling his finger, and in less than one-tenth of a second, his finger would move.

They would bypass his broken spinal cord and put a computer in its place.

The man, Ian Burkhart, was able to move his hand and fingers.

Much of the hope and promise of chips to aid those with spinal cord injuries comes from the 2011 case of Rob Summers, a college baseball star who was injured in a hit-and-run accident and paralyzed below the neck. According to Reuters:

The 2.5-ounce (72-gram) device began emitting electrical current at varying frequencies and intensities, stimulating dense bundles of neurons in the spinal cord. Three days later he stood on his own. In 2010 he took his first tentative steps.

The team wasn’t as optimistic about their next patients – unlike Summers, they didn’t have any sensation in their legs – and they were surprised when four men who were paralyzed from the chest down were able to voluntarily move their legs and feet after being implanted with the device. While the men were not able to walk, the experiment was hailed as a major success and offered new hope for the more than 6 million paralyzed Americans.

What's next? Writing in the Wall Street Journal, two scholars contend "brain implants today are where laser eye surgery was several decades ago." Gary Marcus, a professor of psychology at New York University and Christof Koch, chief science of the Allen Brain Institute for Brain Science in Seattle wonder:

What would you give for a retinal chip that let you see in the dark or for a next-generation cochlear implant that let you hear any conversation in a noisy restaurant, no matter how loud? Or for a memory chip, wired directly into your brain's hippocampus, that gave you perfect recall of everything you read? Or for an implanted interface with the Internet that automatically translated a clearly articulated silent thought ("the French sun king") into an online search that digested the relevant Wikipedia page and projected a summary directly into your brain?

24 of the world's best robots to compete in DARPA Robotics Challenge Finals June 5

Posted 6/2/2015   Updated 6/2/2015 /shared/AFImages/transparent.gif Email story   Print story

from Defense Advanced Research Projects Agency Outreach

6/2/2015 - POMONA, Calif. -- The Defense Advanced Research Projects Agency - the organization that laid the groundwork for the Internet, stealth technology, handheld GPS and much more - invites the public to attend the exciting conclusion of a three-year robotics competition focused on developing robots that can assist humans in responding to natural and man-made disasters. Twenty-four robots/teams will compete simultaneously across four simulated disaster courses during hour-long runs for a chance to win a portion of $3.5 million in prizes.

In addition to the competition, an on-site robotics exposition will include interactive robotics exhibits and demonstrations of technology from more than 70 diverse organizations related to disaster response, robotics and unmanned systems.

The challenge will be held June 5 - 6, from 8 a.m. to 6 p.m. The event is open to the public, free to attend and suitable for all ages. It will be held at the Fairplex in Pomona, California. The address is 1101 W. McKinley Ave. Pomona, Calif., 91768.

The DARPA Robotics Challenge Finals are the culmination of a three-year program to develop robots capable of assisting humans in responding to natural and man-made disasters. It was launched following the 2011 earthquake and tsunami that devastated the Tōhoku region of Japan, with the goal of better preparing humans to confront the threats posed by future disasters.

Through two preliminary rounds of competition, DARPA and the DRC teams have redefined what is possible in robot power efficiency, supervised autonomy, physical adaptability and human-machine control interfaces.

The DRC Finals will now push the teams and robots harder than ever, demanding that the robots operate using only onboard power and wireless communication, without the protection of fall arrestors.

Though the robots may appear to be slow-moving, the gamut of tasks they will face represents one of the most difficult tests of robot hardware and software ever attempted. Each movement the robots will make carries the risk of a potentially competition-ending fall and the hope of earning the $2 million first prize.

The team's human operators will be sequestered in a garage area far removed from the test course, with only data from the robots' onboard sensors to guide them in issuing commands.

Encontrei esta resenha de uma leitura antiga,
que talvez interesse aos adicionados à IA:

Dylan Evans, Emoção: a ciência do sentimento. Li o livrinho editado pela Temas & Debates, capa dura azul celeste, recoberta de uma sobrecapa gráfica cor carmim, com o design de um robô da nova informática afectiva.

A recensão da obra por Desidério Murcho n’O Público de 25 Out. pp., com o título surpreendente «A razão tem emoções que o coração desconhece», deixou-me muito curioso e confiante de o tema ser tratado pelo autor à luz da melhor filosofia e ciência actual, sem concessões ao irracionalismo acrítico dos «livros de auto-ajuda».

O livrinho é um primor, polissemia.

Ekman demonstra (capítulo 1) que as emoções básicas – alegria / angústia; raiva / aversão; surpresa / medo – são universais invariantes de cultura para cultura.

Nos capítulos 2 a 4, Evans historia a evolução das emoções e defende que elas são cruciais para a sobrevivência; discute as «tecnologias do humor» – a linguagem e os prazeres dos sentidos: a cor, os sons, os odores, as massagens, a culinária – que prometem encurtar o caminho para chegar à felicidade; explica como as emoções afectam as capacidades cognitivas, como a memória, a atenção e a percepção.

O capítulo 5 discute os progressos recentes da inteligência artificial na programação -simulação da emoção.

Reconhecendo que há várias maneiras de definir a emoção – pela enumeração dos circuitos neurobiológicos, pelo comportamento observável; pelo papel funcional desempenhado na economia mental; pela asserção da subjectividade como a essência da emoção – pondera que «a capacidade da emoção não é um tudo-ou-nada» e que «existe todo um espectro de aptidões emocionais», do muito simples ao muito complexo.

A informática afectiva procura «construir máquinas com capacidades emocionais cada vez mais complexas». Se um robô estiver programado para prosseguir vários fins potencialmente conflituais, ele só poderá «decidir» se dispuser de um mecanismo interno de «gestão de objectivos». O «dilema do robô» é o nome dado a este problema de gestão de objectivos conflituais. Herbert Simon, em 1967, afirmou «que os robôs precisariam de emoções para o resolver».

Eis o argumento de Simon (p 144):

(1)   Existe um limite para a quantidade de coisas que qualquer agente pode fazer em qualquer momento;
(2)   Se o agente tiver mais de um objectivo, terá de repartir o seu tempo pelas diferentes actividades destinadas a cada objectivo;
(3)   No entanto, o agente tem de manter-se alerta a alterações exteriores que exijam uma mudança rápida de actividade;
(4)   Para tanto, o robô tem de dispor de um qualquer tipo de «mecanismo de interrupção» da actividade que estiver a desenvolver.

Herbert Simon propôs que as emoções fossem precisamente estes mecanismos de interrupção. «Não se trata de uma definição neurobiológica ou comportamental mas de uma definição funcional». Para Simon, «as emoções são aqueles processos mentais que em geral se desencadeiam para interromper a actividade em resposta rápida a uma súbita alteração ambiental

Contudo, um aspecto importante das emoções é o serem imprevisíveis. Ora os computadores limitam-se a seguir um programa. Suas emoções não são verdadeiras porque seguem apenas instruções. Porém, os cientistas informáticos estão criando sequências aleatórias de instruções (algoritmos genéticos) que rivalizam uns com os outros para ocupar espaço no disco rígido do computador, e que podem fazer cópias de si próprios, que podem manifestar eventuais erros, gerando ‘programas mutantes’ que possam melhor dominar o disco duro. Ora, esta vida artificial assemelha-se à selecção natural – hereditariedade (cópias de si), mutação (cópias imperfeitas), réplica diferenciada (alguns com mais cópias do que outros). «O facto de os protagonistas serem sequências de códigos num disco duro e não sequências de nulceótidos num cromossoma não desqualifica a vida artificial em relação à evolução.»

No entanto, é provável que fique irrespondível a objecção de que os computadores afectivos nunca serão auto-conscientes: poderão ter comportamento emocional, mas nunca o sentimento subjectivo, essência da emoção.

Mas não será esta objecção insensata? O que é a consciência? «As emoções que um ser necessita para sobreviver dependem muito do seu estilo de vida e do habitat.» A diferença entre nós e os robôs depende da possibilidade destes desenvolverem tipos de emoções que nos são alheias. Ora, a simpatia implica que aceitemos as emoções dos outros e as sintamos como nossas. Tal é difícil para com os computadores, dotados de uma «fisiologia» diferente da nossa, mesmo que revelem um comportamento semelhante.

Um livro a reler, sem dúvida.

Conclui:

 «Se o coração tem as suas razões, é porque a selecção natural criou as nossas emoções, tal como criou outras faculdades mentais – para nos ajudar a sobreviver e a reproduzir o melhor possível num mundo perigoso e empolgante.»
