Cornell researchers have combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex, and outleap its electric-driven competitors.
Briefs: Internet of Things
Moving robots demands a lot of energy, and batteries, the typical power source, limit lifetime and raise environmental concerns. Researchers at the University of Washington have now created MilliMobile, a tiny, self-driving robot powered only by surrounding light or radio waves.
Briefs: Manufacturing & Prototyping
Centimeter-scale walking and crawling robots are in demand both for their ability to explore tight or cluttered environments and for their low fabrication costs. Pulling from origami-inspired construction, researchers have crafted a more simplified approach to the design and fabrication of these robots.
Briefs: Aerospace
A research team at the Illinois Institute of Technology has for the first time demonstrated the use of a novel control method in a tailless aircraft. The technology allows an aircraft to be as smooth and sleek as possible — making it safer to fly in dangerous areas where radar scans the sky for sharp edges.

A team of MIT engineers is creating a one-megawatt motor that could be a key stepping-stone toward electrifying larger aircraft. The team has designed and tested the major components of the motor.
Briefs: Aerospace
When multiple drones are working together in the same airspace, perhaps spraying pesticide over a field of corn, there’s a risk they might crash into each other. To help avoid these costly crashes, MIT researchers developed a system called MADER in 2020.

Making Satellite, Ground Communication More Effective
Rensselaer Polytechnic Institute’s Moussa N’Gom has devised a method to make communications between satellites and the ground more effective — regardless of the weather.
Briefs: Electronics & Computers
Devices of all types are becoming more intelligent and may include native Ethernet. However, there are many opportunities where proven serial communications will remain the best choice for cost-effective communications.
Briefs: Electronics & Computers
MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique uses about one-millionth the power that existing underwater communication methods use.

Exploiting Signals Broadcast by Multi-Constellation LEO Satellites
Researchers have developed an algorithm that can “eavesdrop” on any signal from a satellite and use it to locate any point on Earth, much like GPS. The study represents the first time an algorithm was able to exploit signals broadcast by multi-constellation low-Earth orbit satellites.
Briefs: Robotics, Automation & Control
Researchers at The Ohio State University have developed new software to aid in the development, evaluation, and demonstration of safer autonomous, or driverless, vehicles. Called the Vehicle-in-Virtual-Environment (VVE) method, it allows the testing of driverless cars in a perfectly safe environment.

A Software Model Makes Transport Robots Smarter
Imagine a team of humans and robots working together to process online orders — real-life workers strategically positioned among their automated coworkers who are moving intelligently back and forth in a warehouse space. This could become a reality sooner than later, thanks to researchers at the University of Missouri.

With a new microscopy technique that uses blue light to measure electrons in semiconductors and other nanoscale materials, a team of researchers is opening a new realm of possibilities in the study of these critical components, which can help power devices like mobile phones and laptops.
Briefs: Semiconductors & ICs
Researchers have developed the world’s smallest LED. It enables the conversion of existing mobile phone cameras into high-resolution microscopes. Smaller than the wavelength of light, the new LED was used to build the world’s smallest holographic microscope.
Briefs: Photonics/Optics
Researchers have outlined a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns to be recognized, thus overcoming the prior limitation of modal distortion in noisy channels.

Engineers have made progress toward lithium-metal batteries that charge as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown — quickly and uniformly — on a surprising surface.
Briefs: Green Design & Manufacturing
Researchers continue to refine the process to improve electrochemical performance. The goal is to balance the benefits and drawbacks of the thicker electrode: It has the potential for higher energy loading and is easy to roll, but it may provide less power, since the ions have further to travel.
