University of Tokyo researchers have developed TRADY (Tilted-Rotor-Equipped Aerial Robot With Autonomous In-Flight Assembly and Disassembly Ability), modular drones capable of linking up in mid-air. This is made possible by using remotely controlled magnets and a docking system similar to those found on refueling mechanisms in fighter jets.
If either TRADY drone detects the risk of collision as they approach each other, they will immediately retreat to their original position. From this safe position, the TRADY system can then attempt to link up again, merging when safe docking is ensured. Practical applications include at construction sites and rescue missions where life saving supplies need to be delivered.

Consider, for instance, the application of aerial robots within an intricate power plant environment. In such scenarios, a robot must navigate to specific task locations while evading collisions with both the surroundings and other robots. In short, flying robots must possess both ‘smallness’ and ‘largeness’. We can address this contradiction with a robot that can operate as a compact module while moving and subsequently assembles into a larger and more potent robot during tasks,” said >Junichiro Sugihara, JSK Robotics Lab Ph.D. Student.
