The flying dragon robot can shapeshift in mid air to squeeze through tight spaces

It may sound like something from an episode of Game of Thrones, but Japanese researchers have revealed an indoor robot called DRAGON that can'shapeshift' in mid air. DRAGON, short for'Dual-rotor embedded multilink Robot with the Ability of multi-deGree-of-freedom aerial transformatiON,' can transform into multiple shapes including a square and a snake. There are not many indoor aerial robots due to constraints coming from door frames, as well as various hazards including windows and furniture. Roboticists in Tokyo developed a robot called DRAGON that can fly indoors. DRAGON counters these hazards by having technology that allows it to transform autonomously based on the constraints of space it needs to pass through.
