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.

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 Continue reading Clearpath Robotics Now Supporting ROS on Windows

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

Undergraduates develop next-generation intelligence tools

The coronavirus pandemic has driven us apart physically while reminding us of the power of technology to connect. When MIT shut its doors in March, much of campus moved online, to virtual classes, labs, and chatrooms. Among those making the pivot were students engaged in independent research under MIT’s Undergraduate Research Opportunities Program (UROP).  With regular check-ins with their advisors via Slack and Zoom, many students succeeded in pushing through to the end. One even carried on his experiments from his bedroom, after schlepping his Sphero Bolt robots home in a backpack. “I’ve been so impressed by their resilience and dedication,” says Katherine Gallagher, one of three artificial intelligence engineers at MIT Quest for Intelligence who works with students each semester on intelligence-related applications. “There was that initial week of craziness and then they were right back to work.” Four projects from this spring are highlighted below. Learning to explore the Continue reading Undergraduates develop next-generation intelligence tools

World Turtle Day Celebrates Final Release of ROS 1

This past Saturday, May 23, was World Turtle Day, the day that celebrates the newest release of the turtle-themed Robot Operating System (ROS)—and also probably some actual turtles—and so we reached out to Open Robotics CEO Brian Gerkey and developer advocate Katherine Scott. We wanted to talk to them because this particular World Turtle Day also marked the release of the very last version of ROS 1: Noetic Ninjemys. From here on out, if you want some new ROS, it’s going to be ROS 2 whether you like it or not. For folks who have robots that have been running ROS 1 for the last 4,581 days (which is when the very first commit happened), it might be a tough transition, but Open Robotics says it’ll be worth it. Below is our brief Q&A with Gerkey and Scott, where they discuss whether it’s really going to be worth all the hassle to switch to ROS Continue reading World Turtle Day Celebrates Final Release of ROS 1

Next generation of soft robots inspired by a children’s toy

Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. But, as anyone who has ever played with a toy popper knows, buckling also releases a lot of energy. When the structure of a popper buckles, the energy released by the instability sends the toy flying through the air. Researchers have harnessed that energy and used buckling to their advantage to build a fast-moving, inflatable soft actuator. More details

High-Speed Robot Arm Hands Off Package to Delivery Drone

Urban delivery drones have their work cut out for them. We’re not really sure whether the whole business model for urban delivery by drone will ultimately make sense, but for it to have a chance at working, drones will certainly benefit from being as energy efficient and time efficient as possible. The biggest waste of time and energy happens during pickup and delivery, where the drone is hovering rather than moving. Hovering is necessary since these drones may be often delivering things (like food and beverages) that need to be kept mostly upright and not delivered by a parachute or something. If you were imagining the ideal drone delivery system, though, it would involve drones flying about at full speed, somehow picking up and delivering items safely without ever having to slow down. The pinpoint accuracy required by something like this isn’t something that we’re likely to see on a drone anytime Continue reading High-Speed Robot Arm Hands Off Package to Delivery Drone
