A lot of Wires
Working with existing electronics, and devising some new systems, we were able to bring the best in current drone technology safely indoors over crowds of people. This involved a lot of tinkering, trial and error and learning new skills.
The design of a blimp involves a lot of testing, so we had to inflate a lot of balloons with helium to try out new designs. This shows one of our first prototypes being inflated for flight testing.
