Scientists from Imperial College London have developed a 3D-printing Micro Aerial Vehicle (MAV) that mimics the way that swiftlets build their nests.
The MAV is a quad-copter, with four blades that enable it to fly and hover. The vehicle, made from off-the-shelf components, carries in its underbelly two chemicals that create polyurethane foam when mixed, and a printing module to deliver the foam. The foam can then be used to build simple structures or repair components.
The texture of the polymer exuded from the 3D printer can also be used to create ’grippers,‘ which stick onto and transport objects to different locations. The MAV could therefore pick up and remove bombs, or dispose of hazardous materials without exposing humans to danger.
The next step for the team is to enable the vehicle to fly autonomously in any environment. The scientists plan to incorporate high-speed cameras and sensors on board the MAV, which will act like a satellite navigation system for tracking and controlling of the flight trajectory.
