Autonomy in Robots
There is a widespread & rapid development of unmanned aircraft (UAV & MAV) equipped withautonomous control systems, called “robotic aircraft” in recent years. Although they can be used forboth civil and military applications, remarkable development has taken place for applications in militaryuse. However, by exploiting the outstanding characteristics of these devices, there are infinitepossibilities of making use of them for civilian use even though applications are not obvious. In thelight of the present scenario, we present here the recent research & development of these autonomousuninhabited aircraft for civilian use.
Chiba University UAV group started research on autonomous control from 1998, continued advancedjoint research with Hirobo, Ltd. from 2001 and realized in a small-scale hobby helicopter fullyautonomous control. We describe here the power line monitoring application of UAV calledSKYSURVEYOR. The helicopter with a gross weight of 48kgs, payload of 20kgs and with variouscameras mounted on them, with cruising time of one hour, catches power line, regardless of theshake of the helicopter. We have also developed another autonomous controlled hobby helicopterSST-eagle2-EX with a gross weight of 5kg - 7kg, payload of 1kg and cruising time of 20 minutes.This is a cheap, simple system, which can be flown by a single person and can be used for sprayingchemicals to fields, gardens, to orchards etc. It can also be used for aerial photographing, forsurveillance and for disaster prevention rescues. This system automated the hobby commercialradio control helicopter.
Chiba University and GH Craft are continuing research and development of autonomous control ofthe four rotor-tilt-wing aircraft. This QTW (Quad Tilt Wing) UAV is about 30kg in gross load, take-offand landing is made in helicopter mode and the high-speed cruising flight is carried out in airplanemode. Although Bell company in the US were the first to make this system and the first flight of theQTR(Quad Tilt Rotor)-UAV was carried out in January, 2006, QTW-UAV is not existing in the worldnow. Scientific observation flights in South pole –the Antartica Exploration using the above system isbeing done at a fast pace and there has been considerable development.
Chiba University and Seiko Epson have jointly tackled the autonomous control of micro flying robot ofthe smallest size in the world, weighing 12.3g. This offers an opportunity as a light weight MAV with
autonomous control in the interior of a room for image processing using a camera. Chiba Universitywith Hirobo, Ltd.has also succeeded in the development of a similar robot, though heavier by 170g.
The configuration of the autonomous control system in the power line monitoring helicopter hasbeen successfully demonstrated in this presentation. Generally, the autonomous UAV used forcivilian purpose consists of a power line monitoring helicopter SKYSURVEYOR as indicated earlier.The various systems which are carried on a Civil used UAV are (i) sensors for autonomous controlsuch as GPS receiver, an attitude sensor and a compass (ii) on- board computer and (iii) a powerlinemonitoring device. These will be dealt in detail in the presentation. The flight of the compound inertialnavigation of GPS/INS or 3D stereo vision base is also possible if needed. From the ground stationoperator assisted flight is also possible. In addition, although a power line surveillance image isrecorded on the video camera of UAV loading in automatic capture mode and it is simultaneouslytransmitted to a ground station, an operator can also perform posture control of a power line monitoringcamera and zooming by interruption at any time. Also, the autonomy ground robot like a hexapodrobot, a dual manipulator robots, and the autonomy marine robot like a robotic boat are brieflyintroduced in this presentation.
