Bex: A walking, rolling quadruped robot that can carry a person around

Posted by in categories: food, robotics/AI

Officials and engineers at Kawasaki have unveiled Bex, a quadruped robot that can walk, roll around and even carry a human passenger on its back—at this year’s 2022 International Robot Exhibition in Tokyo. At the exhibition, Bex was configured to look like an Ibex, a type of wild goat, which is where it gets its name.

Bex was created as part of an effort at Kawasaki the company calls a “robust humanoid platform” with a project called Kaleido. Most such efforts from the project have involved robots that are halfway between human-like robots and wheeled bots. Bex appears to be an aberration—it is a quadruped with on its knees. The robot can walk around, similar in many respects to a quadruped from Boston Dynamics, though much slower. But it also squats down to its knees, locks its joints and fires up a motor that drives the robot around like a car. Bex can also carry cargo (up to 100 kilograms) such as crops or humans. At the , Bex was mounted by an and ridden in circles like a pony. The team at Kawasaki has also made the robot a little glitzier than many of its competitors—it has flashing lights that run up and down its neck and antlers.

Sonoma County Airport Launches Solar Power Systems

Posted by in categories: climatology, government, solar power, sustainability

The Charles M. Schulz Sonoma County Airport had two solar power systems installed onsite and made them live in February. Over the course of their electricity-generating life spans, they will offset thousands of tons of CO2 emissions and potentially save millions of dollars.

Sonoma County has been hit particularly hard by wildfires in the last several years. These natural disasters occur with some regularity on their own, but many believe the latest ones are connected to the effects of climate change. The county has been experiencing higher temperatures and droughts as well. As a result of these challenges, Sonoma County’s government set a goal for the county to be carbon neutral by 2030. The airport solar power installations fit within the carbon-free plan. (The California state government has a goal for California to be operating on clean, carbon-free electricity by 2045.)

Jon Stout, the Sonoma Airport Manager, and Rachel McLaughlin, ForeFront Power’s Vice President of Sales & Marketing, provided some insights to CleanTechnica about the new solar power systems. (The last three answers are from ForeFront.)

Finland Will Store Nuclear Waste in an Underground Tomb for 100,000 Years

Posted by in categories: futurism, nuclear energy

Finland is building a nuclear waste disposal site deep under the tiny city of Eurajoki. Called Onkalo, meaning “deep pit” in Finnish, the nuclear waste repository is slated to open in 2024. If all goes to plan, copper casks will safely store spent uranium fuel rods for at least the next 100,000 years. But what happens when we bury nuclear waste, and how does this fit into Finland’s nuclear future?

Finland is a Scandinavian country about the size of Montana with about five times the population at 5.5 million residents. (That said, Finland is the 216th nation in the world by population density, showing just how sparse Montana really is.) The population is concentrated in the south, with just 200,000 people living around and above the Arctic Circle in northern Finland.

The quantum squeeze

Posted by in categories: electronics, quantum physics

One important recent development in quantum sensing is known as quantum squeezing—a way to circumvent quantum limitations that even quantum sensors have faced in the past.


A technique from the newest generation of quantum sensors is helping scientists to use the limitations of the Heisenberg uncertainty principle to their advantage.

Boeing’s Loyal Wingman drone is now officially the MQ-28A Ghost Bat

Posted by in categories: drones, military, robotics/AI

The first Australian-produced military combat aircraft in over half a century.


Boeing’s Loyal Wingman is now officially the “MQ-28A Ghost Bat.” The new military designator and name that will be used by the Royal Australian Air Force (RAAF) for the autonomous combat drone was announced during a ceremony at the Amberley Royal Australian Air Force Base in Queensland today.

Giving the Loyal Wingman an official name may seem trivial, but it represents two major steps for the program. Being named after a native Australian bat, it acknowledges the first Australian-produced military combat aircraft in over half a century, and it also shows that the drone is moving out of the experimental phase and into a path for full deployment with the RAAF and sales to international customers.
