In the past few years, we have covered plenty of fancy robotic 3D printers here. A group of researchers were inspired by wasps to put 3D printers on drones. In the future, swarms of drones like this can be used to print buildings. To pull this off, the team used scanning drones to track what’s printed to guide the printing drones to the right spot.
Getting printing drones to stay in the right spot can be tricky too. The team created a print head that adjusts its position to compensate for the movement of the drone. Every element on these drones had to be as light as possible to save energy. The above video shows how these drones work.
