In a paper published today in the scientific journal Science, DeepMind demonstrates how neural networks can be used to describe electron interactions in chemical systems more accurately than existing methods.
Density Functional Theory, established in the 1960s, describes the mapping between electron density and interaction energy. For more than 50 years, the exact nature of mapping between electron density and interaction energyâthe so-called density functionalâhas remained unknown. In a significant advancement for the field, DeepMind has shown that neural networks can be used to build a more accurate map of the density and interaction between electrons than was previously attainable.
By expressing the functional as a neural network and incorporating exact properties into the training data, DeepMind was able to train the model to learn functionals free from two important systematic errorsâthe delocalisation error and spin symmetry breakingâresulting in a better description of a broad class of chemical reactions.
Petra emerged from stealth this week, announcing a $30 million Series A. The round, led by DCVC, brings the robotics companyâs funding up to $33 million, with additional participation from ACME Capital Congruent Ventures, 8VC, Real Ventures, Elementum Ventures and Mac Venture Capital.
âWeâve invented a completely new way to excavate rock and this will have profound implications on the future of tunneling,â co-founder and CEO Kim Abrams said in release tied to the news. âBy delivering a boring solution that affordably undergrounds utilities through high-grade rock, we can finally protect communities from exposure to wildfires and ensure the safety of critical infrastructure in disaster-prone areas, especially in places like the Sierra Nevada mountains, Rocky Mountains, and coastal regions.â
The news arrives as the company is announcing a successful pilot of its robot, Swifty. According to the firm, the robot successfully bored a 20-foot tunnel through Sioux Quartzite at a rate of one inch-per-minute. The metamorphic rock is notoriously hard, making it a popular choice for buildings in the upper Midwest region in which it is found. That strength, however, also makes it a formidable challenge from infrastructure and other projects that require tunneling.
Since then, Sophia has spoken to audiences across the globe (in multiple languages), been interviewed on countless TV shows, and even earned a United Nations title (a first for a non-human).
Today, sheâs arguably the most famous robot in the world, but sheâs isnât going to be unique for much longer. Her maker, Hanson Robotics, has announced plans to begin mass-producing Sophia the robot this year â so that she can help the world cope with the pandemic.
As Russia ramps up preparations for a possible assault on Ukraine, President Biden has ruled out sending U.S. troops, but an invasion would still face serious resistance and Ukraineâs defense minister promising a âbloody massacreâ if Russia invades. While Ukraine is heavily outmatched by Russian forces, the threat of heavy casualties is one which Russian cannot ignore. This is why uncrewed systems â remote-controlled robot warriors â could play an important part where the fighting is heaviest.
Soviet Russia shrugged off mass casualties, with Stalin remarking, âOne death is a tragedy; a million deaths is a statistic.â During World War II â the Great Patriotic War to Russians â the Soviet Union lost more than 8 million members of its armed forces, 20 times as many as the United States. Names like Stalingrad became legendary for bloody battles and tough resistance regardless of casualties.
Modern Russia is very different. Unlike Stalin, President Putin cannot ignore public opinion, and his media machine will hide or deny Russian casualties in foreign operations. Mercenaries are increasingly used to keep conflict at armâs length, as the loss of contractors does not play so badly in the motherland.
And it looks a little creepy.
Roboticists at the Italian Institute of Technology (IIT) strapped a fully functioning jetpack onto their humanoid robot, called iRonCub, a report from IEEE Spectrum reveals.
While several outlets have unsurprisingly drawn comparisons to Iron Man, the truth looks far scarier, and like something out of an as-yet unmade horror movie.
In the same configuration as Gravity Industriesâ famous Iron Man-like jetpack design, the iRonCub robot was equipped with four jet engines, giving it the ability to fly. Tests are ongoing, but letâs just say, the team at IIT have struggled at times to keep their robot from igniting, and even exploding, due to the exhaust from the engines.

A team at Swiss-Mile, a spinoff of ETH Zurich has improved upon its ANYmal robot by giving it wheelsâthe result is known as the Swiss-Mile Robot. And by giving it wheels, the robot is now classified as a car, a quadruped and a humanoid robot, depending on its activity at any given time. Like the original ANYmal, the Swiss-Mile has a cartoonish look about it, as if it rolled out of one of the Pixar âCarsâ movies.
It is also deceptively agile. In car mode, it rolls on the ground like a remote-controlled toy car but with much better abilities. It can roll up and down stairs and over objects it has never encountered without hesitation. It keeps on rolling with gusto, moving over any obstacle in its path, lifting up whatever wheels may need lifting, making it a rolling, stepping quadruped. But then it lifts its front end off the ground and rolls or walks on its two rear wheels, like a human on roller skates. Adding wheel lock has really given the robot a lot of options, allowing it to stop rolling, if need be, and to walk on two or four feet.
Watching the Swiss-Mile in action, such as in this YouTube video or this one, one thing is very clear: Wheels are much more efficient in many instances than feet. The robot looks eager to go as it rolls around engaging in acts of nimble agility. Also, unlike Big Dog or its cousins, Swiss-Mile never seems to lose its cool or to hesitate. It never looks afraid to plow forward, like a puppy who has not yet learned that sometimes doing stuff can hurt or result in damage.
Israeli drone manufacturer Airobotics has collaborated with Israeli solar farm services company Solar Drone to develop and supply to Solar Drone a unique solar panel cleaning drone system. The fully automated system will include a drone docking station for automatic battery replacement and cleaning fluid replenishment, enabling the system to operate continuously.
While solar power and solar panels are essentially maintenance-free systems, but solar panels do require cleaning from time to time to enable proper function. Dirt, dust, mud, and bird dropping greatly reduce solar panel efficiency, impacting power output. Frequent cleaning is expensive and time-consuming, especially when panels are remote, difficult to access, or difficult to clean.
A new âdrone-in-a-boxâ-type system is now being developed to do this job. A quadrocopter is housed inside a weatherproof dock located near the solar panels. At regular intervals, the station doors on top will open, releasing the drone. The drone will then take off and fly up to the panels, using LiDAR sensors and mapping cameras for more accurate positioning. Each panel will be sprayed with a cleaning fluid, and after completing the task, the drone will return to the docking station. If necessary, the robotic system will replace the discharged battery with the charged one and replace its cleaning fluid container with a full one.
