One of important subjects for mobile robots is the vision based decision making system, where the color constancy is big problem for robots which use color property to recognize environments. We have been working on color constancy vision algorithms using bio-inspired information processing as creatures can recognize color and shape of objects even if there exits a large change of light conditions...
Underwater robots and underwater machines are counted on helping the salvage procedure, escaping prevention of pollution, lifesaving at sea, scientific exploration in the ocean and so on. In the underwater robot, therefore, Autonomous Underwater Vehicles (AUVs) have been developed actively during recent year. However, AUVs have various problems which should be solved such as motion control, acquisition...
One of important subjects for mobile robots is the vision based decision-making system with environmental recognition. In order to extract features from obtained images, how to realize color constancy by adjusting color property is the important technical issue. We have been working on color constancy vision algorithms using bio-inspired information processing methods as self-organizing map (SOM),...
Various mobile mechanisms have been developed combining linkage mechanisms and wheels, and the combination of passive linkage mechanisms and small wheels is one of research trends to enhance the mobility on irregular terrain. We have been working on a 6-wheeled mobile robot employing a passive linkage mechanism, which achieved climbing capability over a 0.20[m] height of bump and stairs, and developed...
Recently, various mechanisms have been developed combining linkage mechanisms and wheels, especially, the combination of passive linkage mechanisms and small wheels is one of main research trends, because standard wheel type mobile mechanisms have difficulties on rough terrain movements. In our research, a 6-wheeled mobile robot employing a passive linkage mechanism has been developed to enhance maneuverability...

A wheeled mobile mechanism with a passive and/or active linkage mechanism for rough terrain environment is developed and evaluated. In our previous research, we developed a switching controller system for wheeled mobile robots in rough terrain. This system consists of two sub-systems: an environment recognition system using self-organizing map (SOM) and an adjustable control system using neural network...
Autonomous underwater vehicles (AUVs) have great advantages for activities in deep oceans, and are expected as the attractive tool for near future underwater development or investigation. However, AUVs have various problems which should be solved for motion control, acquisition of sensors' information, behavioral decision, navigation without collision, self-localization and so on. In order to realize...
Autonomous underwater vehicles (AUVs) are attractive tools to survey Earth science and oceanography, however, there exists a lot of problems to be solved such as motion control, acquisition of sensor data, decision-making, navigation without collision, self-localization and so on. In order to realize useful and practical robots, underwater vehicles should take their action by judging the changing...
