A major hurdle in the field of robotics is making bipedal robots balance without sacrificing speed. Honda’s ASIMO robot can balance on two legs and walk up stairs, but it is very slow. Luckily, researchers at the Institute for Human and Machine Cognition (IMHC) in Pensacola, Florida have made great strides towards creating a running, two-legged robot … pun intended.

The IMHC recently unveiled the Planar Elliptical Runner robot, the world’s first robot capable of balancing itself without the need for sensors or computers. The Planar Elliptical Runner’s shape and design is the key to its success. Furthermore, the Planar Elliptical Runner can stay balanced while running fast enough to keep up with a moving car.

Torsion springs play a big part in keeping the Planar Elliptical Runner balanced, as these springs are designed to create “reactive resilience.” What this means is if a leg meets resistance, the spring reacts by making the drive cranks feed more power into the leg until it overcomes the resistance. Similarly, extra power is fed into the other leg, so it can maintain a trajectory that prevents the robot from tripping over itself.

The Planar Elliptical Runner is only a proof-of-concept at this point, but senior research scientist Jerry Pratt believes the robot’s design will have numerous applications in the future. “We believe that the lessons learned from this robot can be applied to more practical running robots to make them more efficient and natural looking,” Pratt stated. “Running will be eventually useful for any application that you want to do quickly and where wheels can’t work well. … Robots with legs will be particularly useful in places where you want a human presence, but it’s too dangerous, expensive, or remote to send a real human. Examples include nuclear power plant decommissioning and planetary exploration. These are very small, niche, markets, though.”

The current version of the Planar Elliptical Runner needs glass walls to keep it balanced on a treadmill during tests, as its stability only applies to its front and rear ends. However, the IHMC is already designing a new version that will be stable to its left and right, precluding the need for such walls. We look forward to what the IHMC creates after it has perfected the Planar Elliptical Runner.

With the orchard vision system, farm tools can be turned into AI-powered data recorders

Robots used in farming are not a new idea. We’ve seen machines that pick berries and apples, get rid of weeds, plant trees, move food, and more. Even though these tasks are thought to be the most important parts of automated systems, it’s always been that way in technology: it’s all about the data. One big thing that makes these goods valuable is the amount of useful data that their sensors gather.

Orchard Robotics’ system gets rid of the middle guy in a way. Even so, there is still a lot of value in automating these jobs when there aren’t enough workers. The young company’s system makes it easier to get started by adding a sensing module that can be attached to tractors and other farm vehicles.

There are many farmers who are willing to try new technologies that might help them get more crops or fill jobs that have been hard to staff. However, fully automatic robotic systems can be too expensive for many farmers to even consider.

As the name suggests, Orchard will start out by focusing on apple trees. The system’s cameras can capture up to 100 images per second, each of which records information about a different tree. After that, the Orchard OS software uses AI to turn the data into maps. That includes every bud or fruit that can be seen on every tree, where they are located, and even what color the apple is.

Charlie Wu, founder and CEO, says, “Our cameras take pictures of trees from bud to bloom to harvest. They use advanced computer vision and machine learning models we’ve built to get accurate information about hundreds of millions of fruits.” “This is a huge improvement over the old ways, which involved picking samples of maybe 100 fruits by hand.”

Thanks to the GPS on board, farmers can get a more accurate picture of how well their crops are doing, right down to the location and size of each tree. The company began at Cornell University in 2022. Even though it’s still pretty new, farmers have already started trying the tool. It looks like the field tests from last season were good enough to get real investors interested.

The Seattle-based company will announce a seed round of $3.2 million this week. The general catalyst will lead the round. Humba Ventures, Soma Capital, Correlation Ventures, VU Venture Partners, and Genius Ventures joined the raise. It comes after a pre-seed round of $600,000 that wasn’t made public.

Agility Robotics cuts workforce to focus on commercialization

Agility Robotics stated on Thursday that it had fired a “small number” of workers. The Oregon-based company with lots of money says the job cuts are part of a company-wide push to make more products.

“As part of Agility’s ongoing efforts to structure the company for success, we have parted ways with a small number of employees that were not central to core product development and commercialization,” the company told TechCrunch in a statement. At the same time, we are focused on meeting the huge demand for robots that can walk on two legs in a wide range of commercial settings. To do that, Digit production needs to be sped up, and the company needs to keep winning big customers around the world and create new jobs that help them reach their goals. We think that what we did today will allow us to focus on the things that will help us make Digit a product, sell it, and make more of them.

The two-legged robot Digit, made by Agility, was ahead of its time in the industrial humanoid field. The company grew out of studies done at Oregon State University. Over the years, people have been very interested in its amazing robots with legs. Ford was an early supporter as Agility looked into Digit’s promise for last-mile delivery. In the end, though, those efforts were put on hold while the company focused on stores that were short-staffed.

Agility’s work has had plenty of funding, even though investments and use of robotic systems have slowed down overall. This can be seen as a necessary fix after a huge boom caused by the pandemic.

This month, two years ago, the company announced a $150 million Series B round. Amazon played a big role in the round through its Industrial Innovation Fund. After that, the big store chain said it would test Digits as part of its fulfillment center process. The pilots are over now, but neither company has said what they will do next.

Other companies that make humanoid robots have also announced their own tests in the past few months. Figure with BMW and Apptronik with Mercedes are two examples. At Modex last month, Agility showed off updates to Digit’s end effectors that were made to work better with workflows in the car manufacturing industry.

In the past year, Agility has also hired a number of well-known people, such as Peggy Johnson, CEO of Magic Leap, as CEO, Melonee Wise, CEO of Fetch, as CTO, and Aindrea Campbell, COO, who used to work for Apple and Ford.

Ukrainian officials view ground robots as a significant development in warfare

Milan — The Ukrainian government is currently witnessing a rise in the number of applications submitted by robotics manufacturers seeking to assess the effectiveness of their combat systems. This trend indicates the growing significance of unmanned ground capabilities, particularly in light of the current deadlock on the front lines with Russia.

Brave1, a government defense-technology hub responsible for the development of field-ready capabilities, has recently announced the submission of over 50 ground robotic systems and more than 140 unmanned ground vehicles for evaluation.

In order to improve the Ukrainian army’s capabilities on the battlefield, Brave1 announced on March 12 that it would acquire a sizable number of unmanned ground vehicles (UGVs) through United24. These UGVs are expected to have a transformative impact on the ongoing conflict, similar to the existing role of drones. The Ukrainian government runs a website called United24 that seeks to raise money for the country’s ongoing internal conflicts.

Over the past year, there has been a notable rise in the proliferation of such platforms in military operations, with their utilization and evaluation expanding to encompass a broader range of objectives. Ukrainian social media platforms have lately disseminated video content purportedly showcasing an unmanned ground vehicle (UGV) with the capacity to deploy six anti-tank mines simultaneously.

The online images shared by Brave1 depict a diverse array of compact tracked and wheeled ground robots in motion, armed with firearms, engaged in the evacuation of injured dummies, and seemingly outfitted with technology designed for mine detection.

A prevailing pattern observed in Ukrainian unmanned robots is their tendency to be somewhat light and less weighty compared to their numerous counterparts available on the global market.

According to Nataliia Kushnerska, the project lead at Brave1, Ukraine gains a strategic advantage on the battlefield by employing advanced technological solutions that outperform their adversaries in terms of efficiency, innovation, and cost. These hardware and software products serve as asymmetric responses, capable of altering the configuration during confrontations against the formidable resources of the enemy. This information was conveyed in an email statement to Defense News.

“Ukraine has emerged as a prominent international center for defense technology, and the expansion of this industry will have a crucial impact on Ukrainian defense strategy for many years to come,” she stated.

A considerable quantity of weapons and explosives employed by Russian and Ukrainian military forces persist without detonation, presenting a potential hazard to both military personnel and non-combatants. As of April 2023, it is anticipated that almost 174,000 square kilometers of Ukraine were polluted with landmines.

The impetus to expedite the advancement of Unmanned Ground Vehicles (UGVs) stems from the want to deploy robots for the perilous task of extracting live munitions that remain on the battlefield.
