From IEEE Spectrum:
Skycall is a project from MIT's Senseable City Lab that explores "novel, positive uses of UAV technology in the urban context." It's also a tool to help clueless freshmen find their way around the MIT campus.
The quadcopter itself utilities onboard autopilot and GPS navigation systems with sonar sensors and WiFi connectivity (via a ground station), enabling it to fly autonomously and communicate with the user via the SkyCall app. The UAV also integrates an onboard camera as both an information gathering system (relaying images to a ‘base’ location upon encountering the user), as well as a manually-controlled camera, accessible to the visitor-come-tourist again via the SkyCall app.
Like most conceptual videos, reality is rather far from what's portrayed here, most notably when it comes to the autonomous indoor navigation. But, it might be feasible to have this thing leading students around campus outdoors, as long as they're willing to move at a speed that's compatible with the robot's battery life, and also willing to call campus police when a hapless Frisbee player gets accidentally decapitated.
Also, that is an alarmingly sultry voice for a quadcopter.
