Robots could one day be powered by tree pulp. Researchers at KTH Royal Institute of Technology and Stanford University have developed a method for making elastic high-capacity batteries using nanocellulose from broken down from tree fibres. The battery can be squished, much like foam, and therefore …

Robot Planning Algorithm Tested in Minecraft Model

"The whole of Minecraft is what we refer to as 'A.I. complete.' If you can do all of Minecraft you could solve anything. That's pretty far off, but there are lots of interesting research objectives along the way," says Brown researcher Stefanie Tellex. (Photo credit: Mike Cohea/Brown University.)

A new algorithm could help robots do a better job planning for the complexities of the real world. Interestingly, the code was tested in a video game. Robots often have a tough time planning their actions, in part because they don’t intutively know how to focus …
