#439739 Drugs, Robots, and the Pursuit of ...

In 1953, a Harvard psychologist thought he discovered pleasure—accidentally—within the cranium of a rat. With an electrode inserted into a specific area of its brain, the rat was allowed to pulse the implant by pulling a lever. It kept returning for more: insatiably, incessantly, lever-pulling. In fact, the rat didn’t seem to want to do anything else. Seemingly, the reward center of the brain had been located.
More than 60 years later, in 2016, a pair of artificial intelligence (AI) […] Continue Reading…

#439736 Spot’s 3.0 Update Adds Increased ...

While Boston Dynamics' Atlas humanoid spends its time learning how to dance and do parkour, the company's Spot quadruped is quietly getting much better at doing useful, valuable tasks in commercial environments. Solving tasks like dynamic path planning and door manipulation in a way that's robust enough that someone can buy your robot and not regret it is, I would argue, just as difficult (if not more difficult) as getting a robot to do a backflip.With a short blog […] Continue Reading…

#439730 Faster Microfiber Actuators Mimic Human ...

Robotics, prosthetics, and other engineering applications routinely use actuators that imitate the contraction of animal muscles. However, the speed and efficiency of natural muscle fibers is a demanding benchmark. Despite new developments in actuation technologies, for the most past artificial muscles are either too large, too slow, or too weak.Recently, a team of engineers from the University of California San Diego (UCSD) have described a new artificial microfiber made from liquid crystal elastomer (LCE) that replicates the tensile strength, […] Continue Reading…

#439726 Rule of the Robots: Warning Signs

A few years ago, Martin Ford published a book called Architects of Intelligence, in which he interviewed 23 of the most experienced AI and robotics researchers in the world. Those interviews are just as fascinating to read now as they were in 2018, but Ford's since had some extra time to chew on them, in the context of a several years of somewhat disconcertingly rapid AI progress (and hype), coupled with the economic upheaval caused by the pandemic.

In his […] Continue Reading…

#439721 New Study Finds a Single Neuron Is a ...

Comparing brains to computers is a long and dearly held analogy in both neuroscience and computer science.
It’s not hard to see why.
Our brains can perform many of the tasks we want computers to handle with an easy, mysterious grace. So, it goes, understanding the inner workings of our minds can help us build better computers; and those computers can help us better understand our own minds. Also, if brains are like computers, knowing how much computation it takes them […] Continue Reading…
