Japanese researchers have developed a bizarre flying. shape-shifting dragon robot drone composed of four gimbaled pairs and ducted fans, with each pair connected through a two-axis actuated joint, enabling it to grab things. This means that if there is a valve that needs to be shut in a tight space, dragon would be able to successfully complete the job.
A vectorable rotor unit embedded in each link allows it to perform stable manipulation and grasping of objects in mid-air, while its rotor vectoring apparatus boasts two degrees-of-freedom. Unfortunately, this is still just a research project, as the team still needs to find a way to make the 16.8-pound drone lighter. On a related note, when dragonfly meets R/C ornithopter, this is the result.

The proposed grasping style is unique in that the vectorable thrust force is used as the internal wrench instead of the joint torque. Finally, we show the experimental results of evaluation on the proposed control and planning methods for object manipulation and grasping,” said the researchers.
