Play Tennis with your Quadcopter
For indoor flight this Quadcopter uses 4 Sharp IR sensors, they are able to determine the range of obstacles by bouncing IR light off an object and calculate the angle of return. The flight is amazingly stable, this quadcopter allows for automatic takeoff, landing and hovering. “For the IR range finder (Sharp GP2Y0A02) I needed to use a separate Arduino Pro mini (again we don´t have any analog input free).
