Origami has always been cool, and in recent years it has become an inspiration for self-constructing flat pack furniture and robots. So cool!
This month MIT Prof. Daniela Rus and her team (including U. Sheffiied and Tokyo Institute of Technology) are showing the latest iteration of their research in an ingestible origami robot. It packs into a pill you can swallow (actually, in an ice pellet), and then unfurls and folds into a magnetically controllable robot.
This device builds on several years work, and continues the program to demonstrate all the pieces needed to create ingestible medical robots (which, by the way, biodegrade when finished). When this kind of robot works, it can replace some kinds of surgery, and potentially deliver drugs or therapy to precise locations in the body.
