An anonymous reader quotes a report from ScienceAlert: Nobody knows what sleeping mushrooms dream of when their vast mycelial networks flicker and pulse with electrochemical responses akin to those of our own brain cells. But given a chance, what might this web of impulses do if granted a moment of freedom? An interdisciplinary team of researchers from Cornell University in the US and the University of Florence in Italy took steps to find out, putting a culture of the edible mushroom species Pleurotus eryngii (also known as the king oyster mushroom) in control of a pair of vehicles, which can twitch and roll across a flat surface. Through a series of experiments, the researchers showed it was possible to use the mushroom's electrophysiological activity as a means of translating environmental cues into directives, which could, in turn, be used to drive a mechanical device's movements. "By growing mycelium into the electronics of a robot, we were able to allow the biohybrid machine to sense and respond to the environment," says senior researcher Rob Shepherd, a materials scientist at Cornell. By applying algorithms based on the extracellular electrophysiology of P. eryngii mycelia and feeding the output into a microcontroller unit, the researchers used spikes of activity triggered by a stimulus -- in this case, UV light -- to toggle mechanical responses in two different kinds of mobile device. In controlled experiments, the team used the signals from a fungal culture to govern the movements of a five-limbed soft robot and a four-wheeled untethered vehicle. They were able to influence and override the 'natural' impulses produced by the fungi, demonstrating an ability to harness the system's sensory abilities to meet an end goal. "This kind of project is not just about controlling a robot," says Cornell bioroboticist Anand Mishra. "It is also about creating a true connection with the living system. Because once you hear the signal, you also understand what's going on. Maybe that signal is coming from some kind of stresses. So you're seeing the physical response, because those signals we can't visualize, but the robot is making a visualization." The research has been published in the journal Science Robotics.

Google DeepMind Develops a 'Solidly Amateur' Table Tennis Robot

An anonymous reader quotes a report from TechCrunch: In a newly published paper titled "Achieving Human Level Competitive Robot Table Tennis," Google's DeepMind Robotics team is showcasing its own work on the game. The researchers have effectively developed a "solidly amateur human-level player" when pitted against a human component. During testing, the table tennis bot was able to beat all of the beginner-level players it faced. With intermediate players, the robot won 55% of matches. It's not ready to take on pros, however. The robot lost every time it faced an advanced player. All told, the system won 45% of the 29 games it played. "This is the first robot agent capable of playing a sport with humans at human level and represents a milestone in robot learning and control," the paper claims. "However, it is also only a small step towards a long-standing goal in robotics of achieving human level performance on many useful real world skills. A lot of work remains in order to consistently achieve human-level performance on single tasks, and then beyond, in building generalist robots that are capable of performing many useful tasks, skillfully and safely interacting with humans in the real world." The robot's biggest trouble areas are responding to fast balls, high and low balls. It also has trouble with backhand and the ability to read the spin on an incoming ball. Here's how the researchers plan to address the issue with fast balls: "To address the latency constraints that hinder the robot's reaction time to fast balls, we propose investigating advanced control algorithms and hardware optimizations. These could include exploring predictive models to anticipate ball trajectories or implementing faster communication protocols between the robot's sensors and actuators."

An anonymous reader quotes a report from Ars Technica: Unlike Tesla, which hopes to develop its own bipedal 'bot to work on its production line sometime next year, BMW has brought in a robot from Figure AI. The Figure 02 robot has hands with sixteen degrees of freedom and human-equivalent strength. "We are excited to unveil Figure 02, our second-generation humanoid robot, which recently completed successful testing at the BMW Group Plant Spartanburg. Figure 02 has significant technical advancements, which enable the robot to perform a wide range of complex tasks fully autonomously," said Brett Adcock, founder and CEO of Figure AI. BMW wanted to test how to integrate a humanoid robot into its production process -- how to have the robot communicate with the production line software and human workers and determine what requirements would be necessary to add robots to the mix. The Figure robot was given the job of inserting sheet metal parts into fixtures as part of the process of making a chassis. BMW says this required particular dexterity and that it's an ergonomically awkward and tiring task for humans. Now that the trial is over, Figure's robot is no longer working at Spartanburg, and BMW says it has "no definite timetable established" to add humanoid robots to its production lines. "The developments in the field of robotics are very promising. With an early-test operation, we are now determining possible applications for humanoid robots in production. We want to accompany this technology from development to industrialization," said Milan Nedeljkovi, BMW's board member responsible for production. BMW Group published a video of the Figure 02 robot on YouTube.

Fully-Automatic Robot Dentist Performs World's First Human Procedure

For the first time, an AI-controlled autonomous robot performed an entire dental procedure on a human patient, completing the task eight times faster than a human dentist could. New Atlas reports: The system, built by Boston company Perceptive, uses a hand-held 3D volumetric scanner, which builds a detailed 3D model of the mouth, including the teeth, gums and even nerves under the tooth surface, using optical coherence tomography, or OCT. This cuts harmful X-Ray radiation out of the process, as OCT uses nothing more than light beams to build its volumetric models, which come out at high resolution, with cavities automatically detected at an accuracy rate around 90%. At this point, the (human) dentist and patient can discuss what needs doing -- but once those decisions are made, the robotic dental surgeon takes over. It plans out the operation, then jolly well goes ahead and does it. The machine's first specialty: preparing a tooth for a dental crown. Perceptive claims this is generally a two-hour procedure that dentists will normally split into two visits. The robo-dentist knocks it off in closer to 15 minutes. Here's a time-lapse video of the drilling portion, looking very much like a CNC machine at work. Remarkably, the company claims the machine can take care of business safely "even in the most movement-heavy conditions," and that dry run testing on moving humans has all been successful. [...] The robot's not FDA-approved yet, and Perceptive hasn't placed a timeline on rollout, so it may be some years yet before the public gets access to this kind of treatment.

$5,000 Exoskeleton Pants Promise to Make You a Better Hiker

"The linked article is pretty much a press release, but it's still interesting to see the promise of exoskeletons starting to infiltrate the mass market," writes longtime Slashdot reader Baron_Yam. "These rigs cost $5,000, weigh only a few pounds, and go for multiple hours on a charge." Gizmodo reports: With the MO/GO exoskeleton hiking pants, a traipse through the mountains is becoming more mechanical, not to mention expensive. The MO/GO (short for "Mountain Goat") is a joint effort with established outdoor apparel makers Arc'Teryx and the tech startup Skip. Remember Samsung's exoskeleton pants concepts? These are kind of like that, though Skp and Arc'Teryx's first commercial product covers up all those glaring metal bits with an already-pricey pair of designer hiking pants. The MO/GO is supposed to push you 40% harder, according to the company. What does that mean in context? Fast Company rolled around in them for a hike and found the exoskeleton took a lot of weight off the knee, cushioned footfalls, and kicked the leg forward when tackling an incline. [...] Two braces go into each leg, while the 3-hour power pack sits at the belt line just above your posterior. The MO/GO is a pair of Arc'teryx Gamma pants with cuffs to snap Skip's carbon fiber exoskeletal thighs onto the outside of each leg, which should impact your quadriceps and hamstring muscles. The companies claim each ligament weighs 2 pounds, with the pants in total clocking in at 7 pounds, but instead of adding weight the arms absorb the impact of each step, enough to make users feel "30 pounds lighter." [...] On Skip's site, you can see an internal look at how the motors spin every time the user raises their knee. The pants are supposed to have an on-board algorithm to handle stairs or a steep incline differently. You don't control it with an app either. There are three buttons on the pants: an on/off switch, as well as "less assistance" and "more assistance" toggles.

DHS Has a DoS Robot To Disable Internet of Things 'Booby Traps' Inside Homes

An anonymous reader quotes a report from 404 Media's Jason Koebler: The Department of Homeland Security bought a dog-like robot that it has modified with an "antenna array" that gives law enforcement the ability to overload people's home networks in an attempt to disable any internet of things devices they have, according to the transcript of a speech given by a DHS official at a border security conference for cops obtained by 404 Media. The DHS has also built an "Internet of Things" house to train officers on how to raid homes that suspects may have "booby trapped" using smart home devices, the official said. The robot, called "NEO," is a modified version of the "Quadruped Unmanned Ground Vehicle (Q-UGV) sold to law enforcement by a company called Ghost Robotics. Benjamine Huffman, the director of DHS's Federal Law Enforcement Training Centers (FLETC), told police at the 2024 Border Security Expo in Texas that DHS is increasingly worried about criminals setting "booby traps" with internet of things and smart home devices, and that NEO allows DHS to remotely disable the home networks of a home or building law enforcement is raiding. The Border Security Expo is open only to law enforcement and defense contractors. A transcript of Huffman's speech was obtained by the Electronic Frontier Foundation's Dave Maass using a Freedom of Information Act request and was shared with 404 Media. [...] The robot is a modified version of Ghost Robotics' Vision 60 Q-UGV, which the company says it has sold to "25+ National Security Customers" and which is marketed to both law enforcement and the military. "Our goal is to make our Q-UGVs an indispensable tool and continuously push the limits to improve its ability to walk, run, crawl, climb, and eventually swim in complex environments," the company notes on its website. "Ultimately, our robot is made to keep our warfighters, workers, and K9s out of harm's way." "NEO can enter a potentially dangerous environment to provide video and audio feedback to the officers before entry and allow them to communicate with those in that environment," Huffman said, according to the transcript. "NEO carries an onboard computer and antenna array that will allow officers the ability to create a 'denial-of-service' (DoS) event to disable 'Internet of Things' devices that could potentially cause harm while entry is made."
