We present a new algorithm, Prioritized Sweeping, for efficient prediction and control of stochastic Markov systems. Incremental learning methods such as Temporal Differencing and Q-Iearning have fast real time perfor(cid:173) mance. Classical methods are slower, but more accurate, because they make full use of the observations. Prioritized Sweeping aims for the best of both worlds. It uses all previous experiences both to prioritize impor(cid:173) tant dynamic programming sweeps and to guide the exploration of state(cid:173) space.

The crowd went wild, almost as if it were a World Cup match. Actually, it was RoboCup 2002. The annual robotic soccer tournament was held in Fukuoka, Japan, this past June as the World Cup was getting under way. The timing was no coincidence. The notion of robots taking on Brazil would be laughable if roboticists around the world were not so enthusiastically answering the call.

AMC's latest Sci-Fi show Humans takes us into another world. A world, that....actually, looks incredibly familiar. The streets, the cars, the landscape, the computers, all seem pretty close to our world today. Except for, you know, the eerily humanoid robots that are there to serve humanity's every whim. Those robots, called "Synths," are the centerpiece of a show that tackles our hopes and fears of artificial intelligence.

The Atlas robot looks something out of the post-apocalyptic future, or maybe a Will Smith blockbuster. It's a 330lb cyborg with eerily human-like hands and a head equipped with a laser. This bot will be a first responder in times of crisis, says the Pentagon – it's designed to use tools and trudge through difficult terrain, heading into smoky, dangerous areas that humans can't. With its human capabilities it could also, not coincidentally, be a good soldier. This robot – named Atlas after the Greek mythological hero who supported the world on his back – is part of the Pentagon's quest to create a humanoid robot that can do everything from turning knobs in nuclear plants to driving a car.

In the TV show --Westworld,-- artificially intelligent (AI) robots built to look and act exactly like humans take guests through different narratives of an old-west-styled amusement park in order to help them live out their fantasies -- whether promiscuous, adventurous, or deadly. In episode two of the show, one robot--s glitch gives --Westworld-- employees pause, causing them to decommission it. A scientist in the programming division suggests this glitch may be contagious, --so to speak,-- and could infect other robots, or --hosts-- as they call them in the show. This theory is denied by her superior, but later in the episode, the daughter of the decommissioned robot is shown seemingly infecting another host with "consciousness" by repeating what could--be a trigger phrase:--"These violent delights have violent ends." All of this seems like an eerie (and perhaps, impossible) peek into the future, but Christopher Atkeson, a professor at the Robotics Institute and Human-Computer Interaction Institute at Carnegie Mellon University, told INSIDER that simulated consciousness already exists in products such as Amazon Echo and the iPhone--s Siri, and that AI systems infecting other AI systems is not a hypothetical scenario.

"Let me at least pull the hosts who had contact with him," Elsie asks Bernard.

Warning: There are spoilers ahead for "Westworld." The second episode of "Westworld" made a significant leap when it came to explaining "glitches" in the robotic hosts' programming. One of the programming employees, Elsie, expressed concern to Bernard about Peter Abernathy (the host who went "crazy" in the premiere). Peter Abernathy began reciting threatening lines from his old narratives. "Let me at least pull the hosts who had contact with him," Elsie asks Bernard.

Seven weeks ago, Google made waves in the robotics world with a human-like robot that could walk on uneven terrain, lift boxes and get back up after falling. Such abilities hadn't been seen in one robot. Now Google (formally known as Alphabet) is at it again. Another robot has emerged from X, the company's experimental labs, roaming outdoors on two legs, according to a new video that surfaced from a conference in Japan. While experts call it an impressive demonstration of balance and two-legged walking, it remains unclear what real-world uses Google or anyone could have with a legged robot in the near term. "It will still be awhile before we see these robots in a context outside a very compelling demonstration video," said Brian Gerkey, chief executive of the Open Source Robotics Foundation.
