Assistive exoskeletons are a bit like electric bikes – they do indeed give users a power boost, but part of that boost is needed just to move the extra weight along. Japanese researchers at Hiroshima University and Daiya Industry Co., however, have created a minimalist exoskeleton that does away with heavy batteries and motors. Instead, their Unplugged Powered Suit (UPS) harnesses the wearer's own weight.
The UPS consists of a pump located under the sole of the user's foot, an air hose that runs up the leg from that pump, and what's known as a Pneumatic Gel Muscle (PGM).
With each step that the wearer takes, their foot presses down on the pump. This pushes air up the hose to a hip belt, where it's relayed into the PGM. There, it temporarily causes a gel contained within the device to compress, causing the whole thing to contract and relax like a natural muscle.

I opened the GUI package manager, searching for "emoji" and "utf". lubunicodenames libutf8proc ttf-freefont and noto-fonts-emoji all caught my attention, and after refreshing the page, I can see the emojis above. I'm on arch, Debian may use the same package names, or not, but you should be able to recognize them if the names are different.
