When we think about robots, we think about complex electronic devices. We're conditioned to think about robots as sophisticated machines controlled by intricate programming and powered by advanced ...

This a robot can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer. It can also be printed in one go, from one material. Imagine a robot ...

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or ...

Researchers produced 3D-printed, semiconductor-free logic gates, which perform computations in active electronic devices. As they don't require semiconductor materials, they represent a step toward 3D ...
