In this paper, we propose a new formula to accurately estimate the output value on the real machine of the proposed mechanism as a part of the development concerning the high power joint mechanism. The previously proposed formula did not consider the energy loss when the slider translated. Considering the mass of the slider, we derived an expression that can estimate the angular velocity of the output link from the energy conservation law and the geometrical relationship. As a result of comparing the theoretical value and measured value, the performance of real machine could be more accurately estimated by using the proposed mathematical formula.

This paper presents the information presentation device for alerting 4 dangerous situations on a platform by vibration stimulation of a local position. The vibrator mounted on the information presentation device is provided with vibration isolation to prevent confusion of the presented information. In order to confirm the occurrence of the vibration stimulus at the local position, the measurement experiment of the vibration acceleration was carried out using the acceleration sensor. From the result of power spectrum analysis using the fast Fourier transformation to the measured vibration acceleration, periodic damping was confirmed at a portion other than the vibrator that presents information.

日本広島 2019.06.06 - 2019.06.09

We investigated the adjustment method of exposure times for multi-exposure image fusion. Because the range of luminance in the natural environment is wide, the camera system need to adapt to the ambient light. The proposed system comprises an image sensor module and a field-programmable gate array (FPGA) which is composed of control circuits for an image sensor, HDR image generator/evaluator and control circuits for external modules. In this study, the exposure time adjustment method is to select the combination with the maximum entropy or the minimum sum of squared difference between equalization histogram to original histogram. As a result, we obtained an image where has high contrast all of area.

A tomato harvesting robot that can change the hardware configuration depending on the greenhouse has few development cases, and such robots are also important in terms of operation and development cost. We focus on the tomato harvesting robot that can change only the hardware configuration without changing the basically software configuration. In developing such a robot, it is important to modularize the hardware as the component. Building a distributed system makes it unnecessary to change the software configuration even if the hardware and sensors are changed, and it is possible to develop different robots only by changing the modules. In this study, three tomato harvesting robots with different hardware configurations are developed based on the above development concept. Two types of manipulators and moving mechanisms are introduced. We also report harvest experiments using two manipulators.

With the progress of technology, the realization of a symbiotic society with human beings and robots sharing the same environment has become an important subject. An example of this kind of systems is soccer game. Soccer is a multi-agent game that requires strategies by taking into account each member's position and actions. The behavior of a player changes depending on the game situation, such as the score gap, the remaining time and the importance of the match. In this paper, a futsal game played by agents is observed and analyzed to find a mapping relationship. The strategy in the team is analyzed based on the state vector parameters using a Self-Organizing Map (SOM) and different behaviors are analyzed and compared to achieve, in the future, the best possible result cooperation in a real game.

Tomato fruit harvesting is a labor-intensive process, and therefore robotic automation is required. For tomato fruit harvesting robot, we developed three types of end-effectors (EEs): scissor type, cylinder type and suction-cutting type. It is necessary to harvest the tomato fruit with calyx especially in Japan. Therefore, the proposed EE has a cutter mechanism for cut the peduncle. The results show that the scissor type and the cylinder type EE can cut the peduncle; however, it is difficult to separate one fruit from the cluster. On the other hand, the suction-cutting type can separate and cut one fruit from the cluster and therefore it is useful for harvesting tomato fruit with calyx.

Soil compaction is a form of soil degradation which causes soil erosion, drainage difficulties, and loss of nutrients. To mitigate this issue, in agricultural farms several methods have been adopted. In this paper the preliminary study of a locomotion system with adjustable contact patches is proposed. Aim is to reduce the compaction and optimize the rolling resistance of a grape transporting robot employed in vineyard. A Finite Element Method model supported by experimental results is developed to study the system.

Communication is one of the challenges for UAVs during operations inside tunnels. In this paper, a wireless network system using multiple drones functioning as repeaters is proposed. A number of measurements for Wi-Fi signals are conducted to confirm the effect of different scenarios on the signal in virtual tunnel and real life tunnel. As a result, RSS with -64 dBm can provide five Mbps of bandwidth.

Maintenances of social infrastructures such as dam, bridge are important subjects. The more aging problem going on, the more the effective inspection methods have been expected. In the inspection of dams, divers observe the conditions of their surface manually, however underwater structure deeper than 30m is limited and their inspections are insufficient. In this paper, we propose the ROV whose functions are video capture, indirect measurement using laser, target depth keeping, heading keeping. The ROV is applied into the dam inspection and showed the effectiveness to find cracks. In this study, The Remotely Operated Vehicle (ROV) is developed with the aim of practical application of technologies capable of replacing and supporting dam inspection by diver. Using the developed ROV, we conducted in the 'Verification field of the next generation social infrastructure robot' which was publicly offered by the Ministry of Land, Infrastructure and Transport in FY 2015 and examined its usefulness. In the verification on-site, it was able to satisfy about half of the required inspection items.

Inspection of underwater infrastructure of bridge pier is important for bridge maintenance, however, the underwater environment is dangerous and their observation is one of difficult problems. We have been developing the underwater inspection system which consists of an unmanned surface vehicle (USV) and a remotely operated vehicle (ROV). The concepts of the system are (1) Operation is executable with a small number of persons, (2) USV and ROV are controllable from land or bridge, (3) Build 3D model and images for crack detection. The ROV observes the status of whole infrastructure using cameras and control its posture using a depth sensor and IMU sensor. The USV vertically lifts up and down ROV by winch and carries ROV to the infrastructure. USV has GPS, LRF and IMU for horizontal positioning and pan-tilt control of the camera. In this paper, we discuss the results of the inspection operation test by the robot.
