AGUL AR.Drone is a quadricopter (four wing helicopter) that the Parrot
Co. sells. It is possible to fly freely; going up and down, moving back
and forth and turning around etc. by controlling the rotation number of
four propellers. To prevent the person and the thing being rolled indoors,
hull (cover) for indoor is used (Figure 1) and when enough outdoor space
can be secured, hull for outdoor is used (Figure 2).

There is no worry to be operated by others to do the pairing though AGUL
AR.Drone is usually connected with iPhone(R), Android(TM), and Wi-Fi, and
controlled from the application program. Moreover, a compact front camera
is installed, and the game using AR(Augmented Reality) is possible (Figure
3). This is used in AGUL AR.Drone to display the space and arms in the
game though the electronic information such as CG is usually added and
expressed in the image that takes a picture of a real space in AR. It is
also possible to fight by using two or more AGUL AR.Drone.

An autonomous control for posture maintenance and positional fixation is
performed besides the control received from such an application. A steady
flight is achieved by installing a lot of motion sensors (Figure 4). MIMU
of 6DOF (Miniaturized Inertial Measurement Unit) is used for the control
of the rotation and inclination of the airframe etc. Moreover, the travel
distance is controlled using the measurement result of MIMU and the maintaining
altitude and ascent velocity and falling velocity are controlled by using
ultrasonic wave altimeter.

A high-speed camera under the main body is used for the hovering control
and the groundspeed calculation. Since present location is recognized according
to the camera image, it is not likely to be thrown into the wind. The range
of the flight of AGUL AR.Drone is about 50m, and the direction of height
is also similar. The range of the flight can be expanded by using the repeater
to use Wi-Fi to connect. Lipo battery is used for motive power. The battery
for AGUL AR.Drone of the Parrot Co. can fly for about 12 minutes with 1000mAh.
The extension of the flying time is also possible by the use of an isomorph
and mass Lipo battery.
