Limbless robots may not need lots of complex algorithms when they have mechanical intelligence. Tianyu Wang

We designed wormlike, limbless robots that navigate obstacle courses − they could be used for search and rescue one day

Robots often have a hard time navigating through debris, but robots designed based on worms and snakes could move around obstacles faster, thanks to an idea called mechanical intelligence.

Melding mind and machine: How close are we?

Brain-computer interfacing is a hot topic in the tech world, with Elon Musk’s announcement of his new Neuralink startup. Here, researchers separate what’s science from what’s currently still fiction.
