Over the last few snowfalls in Cambridge, Cristoforo and colleagues flew their DJI Phantom 2 quadcopter, which they previously used in shooting Cold Storage, to document the wintry conditions from above. While piloting, Cris observed instances of icicle build-up on various Harvard buildings from up close, could see how pedestrian traffic was directed through the narrows of cleared pathways, and were also able to see how the storm affected visibility compared to what clear conditions would afford us on the same kind of flights.
Cris and colleagues were careful to observe new FAA regulations by keeping the craft in visual line of sight, and as already had done through the firmware, limited the elevation of our flights to sub-500 feet. The expanse of the spaces captured were in effect stitched together from a number of shorter flights, which was also necessary due to the battery-life limitations of the craft on a single charge. The on-board transmitter Cristoforo manually installed also enabled a video downlink to see what the onboard GoPro is seeing in its immediate vicinity, for a second visual reference. As another safety measure, Cris ensures that the quadcopter has a GPS-link before taking off, which has it return to hover over its starting location in the instance of any issue due to interference or incapacitation of the pilot.
Getting to these kind of visuals has been a gradual learning process, taking numerous test flights to understand how well the drone corrects its own position due to wind drift, how immediately responsive it is at various altitudes, and developing refined motor skills for the operation of the remote control. Through responsible usage, Cristoforo hopes to provide a unique vantage point for numerous other metaLAB projects and initiatives.
