Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.

Compounding this mechanical challenge is the fact that many advanced robots are being developed to work outside constrained ...

Students from ETH Zurich have built a high-speed multi-material metal Laser Beam Powder Bed Fusion (PBF-LB) Additive ...
