Heart surgery stalled as COVID-19 spread

Two recent journal articles explore how hospitals worldwide scaled back on heart surgeries as the pandemic hit, and how they can resume those operations in a world still plagued by the SARS-CoV-2 virus.

Clearpath Robotics Now Supporting ROS on Windows

Part of the appeal of the Robot Operating System, or ROS, is that it’s much faster and easier to get started with robots because so much of the difficult and annoying groundwork is already done for you. This is totally true, but for many people, getting started with ROS adds a bunch of difficult and annoying groundwork of its own, in the form of Linux. All kinds of people will tell you, “Oh just learn Linux, it’s not so bad!” But sometimes, it really kind of is so bad, especially if all you want is for your robot to do cool stuff.

Since 2018, Microsoft has been working on getting ROS to run on Windows, the operating system used by those of us who mostly just want our computers to work without having to think about them all that much (a statement that Linux users will surely laugh at). For that to be really useful to the people who need it, though, there needs to be robot support, and today, Clearpath Robotics is adding ROS for Windows support to their fleet of friendly yellow and black ground robots.

Zipline Launches Long Distance Drone Delivery of COVID-19 Supplies in the U.S.

Eighteen months ago, we traveled to Rwanda to see how Zipline had made fast, dependable drone delivery a critical part of medical supply infrastructure on a national scale. But outside of Africa, Zipline’s long-distance delivery drones have had to contend with complex and crowded airspace, decades of stale regulation, and a healthcare system that’s at least (sort of) functional, if not particularly agile. 

Along with several other drone delivery companies, Zipline has been working with the U.S. Federal Aviation Administration (FAA) on small scale pilot projects over the past year or so to prove out the drone delivery concept, but progress has been slow. Now, though, COVID-19 has put enough additional stress on the U.S. healthcare system that the FAA has granted an emergency waiver to the Part 107 drone rules to allow North Carolina–based Novant Health to partner with Zipline on a beyond line-of-sight autonomous drone delivery service through controlled airspace—the first of its kind in the United States.

Computer vision and uncertainty in AI for robotic prosthetics

Researchers have developed new software that can be integrated with existing hardware to enable people using robotic prosthetics or exoskeletons to walk in a safer, more natural manner on different types of terrain. The new framework incorporates computer vision into prosthetic leg control, and includes robust artificial intelligence (AI) algorithms that allow the software to better account for uncertainty.

Avalanche photodiode breaks performance record for LiDAR receivers

Electrical and computer engineers have developed an avalanche photodiode that achieved record performance and has the potential to transform next generation night-vision imaging and Light Detection and Ranging (LiDAR) receivers. For LiDAR, the team’s low-noise, two-micrometer avalanche photodiode enables higher-power operation that is eye-safe.
