The Massachusetts Institute of Technology (MIT) recently launched a drone tour guide called 'Skycall,' developed by Senseable City Laboratory customized to help the average freshman by helping to navigate them through complex environments. Skycall is an "autonomous flying quadcopter and personal tour guide -- operating in one of mankind's most difficult and disorientating labyrinths: MIT campus."
The drone uses UAV technology to autonomously sense and see its environment and has the ability to interact with real people. There is even an app for your smartphone that custom tailors your destinations for you depending on where you want to go. The quadcopter has an autopilot, a camera, GPS navigation system coupled with sensors and WiFi connectivity enabling communication between the drone and the target user.
Once the user calls the drone with a smartphone, the drone will automatically receive the user's GPS location, locate the target and fly to them.
