A system and method of controlling quadrotor air vehicles (QRAV) that may include an additional two degrees of freedom for each of the four propellers of the QRAV. Each of the four rotors may be allowed to rotate (tilt) around two local axes selected from the x-axis (roll), y-axis (pitch), and z-axis (yaw).

The proposed system, Delayed Telop Aid (DTA), improves the teleoperator's ability to control the vehicle in a three step process. First, DTA predicts robot motion given the operators commands. Second, DTA creates synthetic images to produce a video feed that looks as if the robot communication link had no delay and no reduced bandwidth. Finally, DTA performs closed loop control on the robot platform to ensure that the robot follows the operator's commands. A closed loop control of the platform makes sure that the predicted pose after the delay (and therefore the image presented to the operator) is achieved by the platform. This abstracts away the latency-sensitive parts of the robot control, making the robot's behavior stable in the presence of poorly characterized latency between the operator and the vehicle.
