The big picture features technology through the lens of photographers.
Per month, IEEE Spectrum It selects the most amazing tech photos recently captured by photographers around the world. We choose photos that reflect an important progress, a trend, or those that are amazing to look at. We display all the images on our website, and one also appears in our monthly print edition.
Enjoy the latest images, and if you have suggestions, leave a comment below.
RoboCup class image
Have you ever been in awe of the Parade of Nations at the Olympics opening ceremony? Then this photo, featuring Nao’s 100+ programmable learning robots, two Pepper assistive robots, and their human therapists, should leave you similarly amazed. Taken at the end of this year’s RoboCup 2022 competition in Bangkok. Two years after the collapse of RoboCup due to the global pandemic, organizers have managed to bring together 13 teams of robots from around the world (with three teams joined remotely) to participate in the robot car games. The spirit of the gathering is captured in this photo, which, according to the RoboCup organizers, shows bots with a combined market value of around US$1 million.

Longest distance for calls
When you travel to faraway destinations, it’s comforting to know that you can keep in touch with people back home, no matter how far you walk. However, it is very easy to end up in a place with poor cellular reception or nothing to talk about. This is because only about 10 percent of the world’s surface is in cellular coverage areas. But in April 2022, a company called Lynk launched the Lynk 1, which is poised to be the world’s first commercial satellite cell tower, into space. The cell tower, pictured here, is said to be the first of four that Link plans to launch into orbit this year. Once contracts are in place with land-based cellular providers, 4 billion people with barely a proper cellular reception will be able to respond in the plural when asked, “How many bars have you got?”
dead Than using a 3D printer to make parts for a 3D printer? This device looks like a set of separate tubes grouped together. But it’s actually a single unit built that way inside a 3D printer. It is a precision-engineered heat exchanger – optimized to improve the cooling of the protective gas that prevents impurities from contaminating the additive manufacturing process that occurs inside an industrial 3D printer. There is no paper jam here.
Nothing is worse for wear
How can we take advantage of the physical and cognitive improvements that wearable electronic devices can one day provide if everyday aspects of human life such as breaking a sweat are dangerous for these devices? do not worry. In a recent paper, a research team at the University of California, Los Angeles, reports that the problem is solved. They have developed a human-machine interface that is impermeable to moisture. And as if the water resistance wasn’t enough, the four-button device is designed to generate enough electric current to power its operation when any of the buttons are pressed. So, it can go anywhere we go, without any concerns about spills, stains, sweat or spent batteries.
