Aerotain, a Spin-Off of one of Switzerland’s top universities ETH Zurich, shows a flying robot called Skye that is safe enough to fly above crowds and be touched in midflight. Helium provides uplift, even if technical problems occur and thus does not hurt anybody. The individually branded hull together with a live stream allow the audience to experience the brand. This is a new tool that marketing agencies and event organizers can consider as one great attention grabbing display/branding/projector drone.
