The General Robotics, Automation, Sensing and Perception (GRASP) Laboratory (University of Pennsylvania) integrates computer science, electrical engineering and mechanical engineering in a vibrant, collaborative environment
The autonomous quadrotors each have a gripper mounted on their underside that can lift and place either horizontal or vertical components.
The components snap together with the aid of magnets, and the quadrotors can jiggle the beams to ensure they are correctly in position.
Using magnets and flux pinning will be even more useful in space
