This experimental method can be applied to any size and type of object. In particular, it can be most effectively used for small unmanned aerial vehicles (UAVs). The model vehicle is suspended by two thin light weight low-stretch lines vertically attached to two hook points on the model and provided with a free rotational oscillation to estimate the moment of inertia around the vertical axis through the center of gravity. This procedure is repeated at different attitude angles so that the moments of inertia around different axes can be calculated and used in the estimation of all components of the moments and products of inertia in the form of an inertia matrix, using a multivariate regression equation.. |

Evolutionary Computation is used for the optimization of the traveling order of the waypoints which are specified for a certain mission, and for the optimization of the number and positions of the additional waypoints inserted in order to avoid obstacles. The additional waypoints are inserted following the predetermined rule so that the efficiency of the obstacle avoidance improves.. |

The original PIP method is a genetic algorithm-based (GA-based) optimization method that can efficiently generate a preferred solution for a decision-maker. However, there are two problems occur when this method is applied to the DDP. The first problem is that there exist some cases wherein the evaluation function becomes infinite in the search process, making it impossible to sort the generated solutions. The second problem is that a long time is needed for the solution search to converge. Accordingly, the process had to be aborted at the halfway point. We present an improved PIP method to overcome these two problems. The proposed method is a solution search comprising a GA combined with tabu search. It converts the DDP into a single-objective optimization problem of a delivery cost using conversion factors. This paper presents several things understood regarding the cost-reduction effect on drone delivery services using our newly proposed method.. |

Hiroki Omagari, Shin-Ichiro Higashino, Aspiration-Point-Based Multi-Objective Path Planning Method for an Unmanned Aerial Vehicle, TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, AEROSPACE TECHNOLOGY JAPAN, 10.2322/tastj.15.a99, 15, APISAT-2016, a99-a108, 2017.03, This research presents a new multi-objective path planning method for an unmanned aerial vehicle (UAV) using evolutionary computation. The proposed method searches for a desirable Pareto-optimal solution using an “aspiration point” and an “ideal point.” The aspiration point refers to the preference information for a decision maker (DM), and the ideal point represents a virtual solution that optimizes all objective functions simultaneously. All of the solutions generated in using evolutionary computation evolve toward the aspiration region, which is determined by the aspiration point. If a solution that is closer to the ideal point than the aspiration point is generated in the search process, the aspiration point is moved to the position of the solution point. This process is repeated until specific termination conditions are satisfied. Some results of the benchmark test problems show that the proposed method can efficiently generate the Pareto-optimal solution for the DM and a high probability compared to the existing method called the “weighted-sum method.” The usefulness of the proposed method is also shown by applying it to a multi-objective path planning problem that assumes an aerial photo-shoot mission using a UAV.. |

, 7th Asia-Pacific International Symposium on Aerospace Technology, 2015.11, The authors have developed a new aerosol observation and sample-return system using a balloon-assisted UAV for easy recovery of the observation apparatuses and samples. Although the balloon-assisted small UAV has reached and returned from the altitude of 10km in January 2013 in Antarctica, it is necessary to raise the observation altitude up to 30km from the standpoint of aerosol observation. However, it is difficult to estimate aerodynamic characteristics of such a small UAV in such region. In order to solve the problem, the authors devised the method named “two-stage separation method” in which we can choose the start altitude for gliding and estimating aerodynamic characteristics step by step by parachuting down the UAV until it reaches the start altitude for gliding after separated from the balloon. This paper shows the details of the method and the result of the flight performed in 2015 in Antarctica. |

These UAVs have a maximum flight range of 300-500km. We planned aeromagnetic and aerial photographic surveys using the UAVs around Bransfield Basin, Antarctica, beginning from King George Island. However, we were unable to complete these flights due to unsuitable weather conditions and flight restrictions. Successful flights were subsequently conducted from Livingston Island to Deception Island in December 2011. This flight covered 302.4km in 3:07:08, providing aeromagnetic and aerial photographic data from an altitude of 780m over an area of 9×18km around the northern region of Deception Island. The resulting magnetic anomaly map of Deception Island displayed higher resolution than the marine anomaly maps published already. The flight to South Bay in Livingston Island successfully captured aerial photographs that could be used for assessment of glacial and sea-ice conditions. It is unclear whether the cost-effectiveness of the airborne survey by UAV is superior to that of manned flight. Nonetheless, Ant-Plane 6-3 proved to be highly cost-effective for the Deception Island flight, considering the long downtime of the airplane in the Antarctic storm zone.. |

The aerial vehicles were scheduled to conduct aero magnetic and photographic surveys of the Bransfield Basin, from a takeoff runway at Marsh Airfield on the South Shetland Islands, Antarctica, during January 2011. However, the scheduled surveys were not conducted on account of poor weather. Research was later conducted on a glacier, using a takeoff runway at St. Kliment Ohridski Base, Livingston Island, during December 2011. A flight from St. Kliment Ohridski Base to Deception Island yielded satisfactory results; the total distance of 302.4 km was traversed in 3 h 7 min (3;07). On this flight, aeromagnetic and aerial photographic data were obtained from an altitude of 780 m for a 9 ×18 km area on the northern half of Deception Island. Aerial photographs of Deception Island and South Bay showed the distributions of glaciers and their crevasses. The Ant-Plane flew over the Antarctic horizon and surveyed above Deception Island. That was the successful venture of this kind, demonstrating that airborne surveys by Ant-Planes are useful for Antarctic research investigations. Airborne surveys provide a safe and economical approach to data acquisition as compared with manned aerial operations.. |

The UAV fleet is divided into three groups, i.e., a small UAV for low altitude, relatively large UAVs for mid-altitude, and a small glider UAV for high altitude. Several results, operational experiences of the UAVs, lessons learned including the operations in Antarctica, and several problems to be solved are reported in this chapter.. |

The Ant-Plane 2 cruised within 30 m of the planned course during calm weather at Sakurajima Volcano on Kyushu. During strong wind, 22 m/s, at Chokai Volcano, northern Honshu, the drone remained on course during straight flight but deviated when turning leeward. An onboard magnetoresistant magnetometer (400 g) recorded the variation of magnetic field with accuracy of 10 nT in calm wind, but strong magnetic noise was observed in strong wind, especially a head wind. The Ant-Plane 4 achieved a continuous flight of 500 km and the highest flight altitude of 5700 m. The Ant-Plane UAV can be used for various kinds of Antarctic, requires further development of techniques for easy takeoff and landing and easy start of engines.. |

To make clear the differences between successful results obtained by an experienced hand and by a non-experienced one, three operators wereselected for three successive experimental days; an engineer who had never experienced any biological experiment, a non-biology student, who experienced on biological experiments, and a veterinary surgeon. Surgical procedures need much experiences on maneuvering and understanding of theory to shorten the elapse time. Especially for a non-experienced hand, graphic instructions were much helpful to understand and to maneuver the procedures. Continuous recordings of ECG from a operator and PIs were of an advantage to grasp an extent of the mental strain, which was compared with their reports requested after end of each experimental day. The mental strain was not related to degrees of scientific achievement, but showed faithfully difficulty of each experimental procedure. Training effects on PIs in successive experimental days were found in their instructions for the operator to let understand the procedures.. |
