NASA’s Perseverance Mars rover is using its self-driving capabilities as it treks across Jezero Crater seeking signs of ancient life and gathering rock and soil samples for a planned return to Earth. With the help of special 3D glasses, rover drivers on Earth plan routes with specific stops, but increasingly allow the rover to “take the wheel” and choose how it gets to those stops. Perseverance's auto-navigation system, known as AutoNav, makes 3D maps of the terrain ahead, identifies hazards, and plans a route around any obstacles without additional direction from controllers back on Earth.

The Suzumori Endo Lab at Tokyo Tech has developed a soft tensegrity robot driven by thin artificial muscles, the movement of which makes me vaguely uncomfortable.

MIT engineers have developed a telerobotic system to help surgeons quickly and remotely treat patients experiencing a stroke or aneurysm. With a modified joystick, surgeons in one hospital may control a robotic arm at another location to safely operate on a patient during a critical window of time that could save the patient’s life and preserve their brain function.

The M1600 was designed for high-volume robotic applications with direct input from our customers. This durable and compact sensor can be deployed in a wide variety of environmental and weather conditions, allowing for 365-day, 24/7 usage. It can provide the smart, real-time point clouds required by autonomous mobile robots and last-mile delivery for safe and extended operation without human intervention.

Getting drones to perch on vertical surfaces would be much easier if we just covered the world in velcro, wouldn’t it?

An upcoming ICRA paper from Kostas Alexis at the Norwegian University of Science and Technology about the SubT strategy of Team Cerberus.

This paper presents a novel strategy for autonomous teamed exploration of subterranean environments using legged and aerial robots. Tailored to the fact that subterranean settings, such as cave networks and underground mines, often involve complex, large-scale and multibranched topologies, while wireless communication within them can be particularly challenging, this work is structured around the synergy of an onboard exploration path planner that allows for resilient long-term autonomy, and a multirobot coordination framework.

The CMU Teruko Yata Memorial Lecture is presented by Jeannette Bohg from Stanford, on Leveraging Language and Video Demonstrations for Learning Robot Manipulation Skills and Enabling Closed-Loop Task Planning.

Humans have gradually developed language, mastered complex motor skills, created and utilized sophisticated tools. The act of conceptualization is fundamental to these abilities because it allows humans to mentally represent, summarize, and abstract diverse knowledge and skills. By means of abstraction, concepts that we learn from a limited number of examples can be extended to a potentially infinite set of new and unanticipated situations. Abstract concepts can also be more easily taught to others by demonstration.

Practical Power Beaming Gets Real

A century later, Nikola Tesla’s dream comes true

This nighttime outdoor image, with city lights in the background, shows a narrow beam of light shining on a circular receiver that is positioned on the top of a pole.

A power-beaming system developed by PowerLight Technologies conveyed hundreds of watts of power during a 2019 demonstration at the Port of Seattle.

Wires have a lot going for them when it comes to moving electric power around, but they have their drawbacks too. Who, after all, hasn’t tired of having to plug in and unplug their phone and other rechargeable gizmos? It’s a nuisance.

Wires also challenge electric utilities: These companies must take pains to boost the voltage they apply to their transmission cables to very high values to avoid dissipating most of the power along the way. And when it comes to powering public transportation, including electric trains and trams, wires need to be used in tandem with rolling or sliding contacts, which are troublesome to maintain, can spark, and in some settings will generate problematic contaminants.
