This dual cross-linking design lets the muscle switch stiffness on demand. In lab tests, its stiffness jumps from about 213 kilopascals — soft, like rubber — to 292 megapascals, hundreds of times ...

Magnetic graphene oxide sheets fold, move, sense motion, and switch function by swapping magnetic layers, offering a fast, reprogrammable platform for soft robots and other morphable structures.

There are many incredible open-source robotic arm projects out there, but there’s a dearth of affordable, stable, and mobile robotic platforms with arms. That’s where XLeRobot comes ...
