In response to labor shortages due to an aging population and the vast and complex terrain of forests, this research focuses on generating 3D maps using multiple small drones equipped with monocular camera. By leveraging advanced image processing techniques, we try to achieve high-precision 3D mapping from images captured by multiple drones, efficiently covering extensive terrains. This approach is expected to contribute to forest management and rapid disaster assessment.

In the early stage of BMI research, studies attempted to classify natural thoughts such as“ I want to go left ” or “ I want to go right ” based on EEG signals, but the classification accuracydid not improve. Consequently, to enhance accuracy, more classifiable yet unnatural thought patternswere employed. However, controlling BMI with unnatural thoughts is challenging. Moreover, currentEEG measurement devices and analytical methods have progressed since the early BMI research days.Therefore, this study aims to verify the feasibility of bidirectional classification based on natural thoughtsusing various analytical methods, including deep learning techniques.

In this study, we developed a system for a small flapping-wing robot, which mimics bird flight and is being developed to address issues of noise and safety associated with drones, to follow a target object by equipping it with a camera. Specifically, we developed a mechanism to transmit camera information from the flapping robot to a PC via Wi-Fi, detect and track the target object in real time using OpenCV, and transmit control signals to the robot via Wi-Fi. In the future, we aim to achieve tracking control in an actual flying state.

Bounding flight is a form of flight in which small birds, such as sparrows, quickly flap their wings to gain upward momentum and then fold their wings for ballistic flight. The bounding flight reduces the number of wing flaps, which is expected to reduce battery consumption. The flapping motion is made possible by a gearbox with a crank mechanism. Folding motion is made possible by a micro servo motor and a link mechanism made of carbon plates.

There is a type of flying robot called a flapping flying robot. By controlling the flapping angle, the center position of flapping motion, and flapping frequency, servo-type flapping flying robots achieve not only flapping flight but also various flight forms such as ascending/descending, turning, flipping, and gliding. In this research, an IMU sensor is equipped to a servo-type flapping flying robot, and we try to achieve hovering flight by changing the pitch angle of the flapping robot by controlling the center position of flapping motion.

In order to further advance the research and development of flapping flying robots and to incorporate them into our daily lives, it is necessary to make more researchers and the general public recognized and interested in flapping flying robots. Therefore, it is necessary to search for a safe, simple, and easy to-understand manufacturing method. In this research, we developed a servo-type flapping flying robot that anyone can easily create so that it can be recognized as more familiar research themes.

In recent years, the development of aircrafts with good environmental performance is required to address the global warming problem, and the reduction of aerodynamic drag is an important issue in the development of aircrafts. A wingtip vortex suppression device called a winglet is mounted to the tip of airplane wings. Winglets are modeled after the upturned feathers on the wingtips of gliding hawks and eagles. Winglets have been shown to improve the performance of airplanes by 10% or more. The development of the shape of winglets must be considered in combination with other aspects such as the increase in weight and drag due to the addition of winglets. In this study, we developed flapping wing aircrafts with winglets and compared performances in order to find the optimal winglet mounting angle for flight.

UAVs have challenges in terms of safety and cruising range. A flapping flying robot has the potential to be a superior UAV in these aspects. The flapping motion is an oscillating motion and is safe. In addition, flapping flight robots don’t necessarily require flapping motion to sustain flight. In this study, we focused on bounding flight and aimed to achieve it with a flapping flight robot. Bounding flight is a flight method that many small birds perform by intermittently folding their wings during flapping flight. Therefore, to perform bounding flight, it is necessary to perform both the flapping motion and the wing folding motion. We have developed a flapping wing flying robot that can perform these motions and mimic bounding flight.

In recent years, research and development of unmanned aerial vehicles(UAV) has been active. However, they are easily affected by wind. In this research, aiming at the achievement of a flight robot that enables long distance flight using a wind like birds, we estimated the upwind direction from sensor data and performed steering control of the flying robot in the upwind direction.

The objective of this research is to develop a flapping flying robot that can achieve bird-like flight using helium gas-infused airfoil-shaped balloon wings. Wings must have an airfoil shape in order to generate lift by flapping its wings. However, the wing becomes heavy when it has a skeleton to achieve the airfoil shape. In this research, we used aluminum balloons filled with helium gas to create airfoilshaped balloon wings similar to actual bird wings, and tried to measure lift and thrust and perform flight experiments.

In recent years, studies on BMI and BCI, which use EEG as an interface for operating external devices, has been actively conducted. In many of those studies, an electroencephalogram classifier individualized to one subject has been created from the electroencephalogram data of the subject. This is because EEG data of one subject is said to be quite different from other subjects, and an individual classifier has advantage for increasing the classification rate. In general, a large amount of data is required for constructing the individual classifier. As a result, the burden of subjects increases. In this study, we input a small amount of EEG data of different subjects into the pre-built individual classifiers for multiple other subjects and compare the classification rates. We show that, without building a classifier individualized to one subject, there is a possibility to be able to use other subject’s individual classifier that has already been built.

In this research, we aim to develop a flapping flight robot that can generate large lift force by wings and that realize flight close to real birds. In order to obtain large lift force, it is necessary to give a wing cross-sectional shape (airfoil) to the wing. In this paper, we attempted to manufacture a balloon wing with a shape close to the airfoil using a balloon filled with helium gas. We also developed a flapping flight robot using the manufactured balloon wings and investigated its flight feasibility.
