Saliency is a property of images that triggers bottom-up attention. For example, if a location in an image is sufficiently different from its surrounding and worthy of paying attention, such characteristic of image is saliency. From the point of view, the location of larger saliency is outstanding visually. On the other hand, As Image Feature extraction method, such as SIFT or SURF, robust feature matching has been realized under the existence of changing size or rotation of observed target. For the consequence, its advantage has been introduced into image stitching and Visual SRAM. However, the amount of image features is susceptive to changing photographing condition, such as luminance variety, defocus-ing etc. We assumed that feature extraction stability is large in salient region because of steep bright-ness gradient. We evaluated the relationship between saliency and feature extraction stability.

In order to improve the efficiency of the seafloor survey, it is necessary for AUV to report the state of the seafloor to the operators on board reasonably. We have been developing seafloor image selection and image compression technology for the seafloor image transmission using the underwater acoustic communication device. In this paper, we report the results of underwater image selection and transmission in biological sampling experiments conducted in November 2019 off the coast of Suruga-bay, Shizuoka, Japan.

Tomato is one of the important fruit vegetables and most tomatoes are produced in the greenhouses, or large-scale farms, where the high temperature and humidity, and long harvest age force the farmer heavy works. To develop the tomato harvesting robot, many research issues exist such as manipulator design, end-effector design, collaborative behavior, artificial intelligence, motor control, image processing, target recognition and so on. With an aim to promote the automation of tomato harvesting, we have organized the tomato harvesting robot competition since 2014. In this paper, we report on the results of 5th tomato harvesting robot competition in 2018.

Acquiring flexible and agile behaviors as seen in biological systems, the robot can achieve acrobatic movements such as jumping and throwing. These acrobatic movements are expected to extend the range of robot activity. In this research, we propose a special mechanism using a pair of motors, springs and cams, which has three functions: normal operation, instantaneous operation and variable rigidity. Then, we derived a mathematical model of the mechanism and discussed the input-output characteristics of the mechanism by changing the design parameters, and analyzed the difference between the theoretical and measured results.

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. In this paper, we discuss the results of the development of a learning system that uses SOM to select behaviors depending on the situation.

Animals can achieve agile behaviors such as jumping and throwing in addition to flexible behaviors with the same musculoskeletal systems, and those movements can extend the range of their activities. We have been working on actuators capable of rapid and flexible motions learning the musculoskeletal systems. In this paper, we propose a new rotary actuator using a pair of motors, springs, and cams to perform three functions, namely, normal motion, rapid or instantaneous motion, and rigidity control using an antagonistic cam mechanism, and describe the operating principle of the proposed mechanism, the mathematical model of the mechanism during rapid motion, and the design principle of the cam, which is a key mechanical element in this mechanism. Finally, we present an analysis of the error between the theoretical the measurement results during rapid motion.

<p>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.</p>
