Biological creatures, some of them are very simple, seem to perform efficient search strategy. Recent researches show that noise in their internal mechanism may have an important role to manage this behavior. This paper focuses on realizing a simple, noise utilizing, mathematical framework that enables a mobile robot to perform random search adaptively and efficiently under changing target density...
Living organisms have various kinds of flexibility and robustness which are realized by ??yuragi,?? i.e. biological fluctuations or noises. Bacterial motion is a form of noise-based motion, since bacteria can move towards a higher concentration of some chemical which they prefer even though they have only a limited 1-DOF of flagella for mobility. Bacteria also have only a limited sensory device which...
Many biologically inspired approaches have been investigated in relation with researches on mobile robot(s) that can effectively locate targets that induce gradient information. Here, we concentrate on realizing an adaptive searching behavior in mobile robot that is simple, yet effective with and without sensing the gradient information. We are interested in two searching behaviors found in biological...
We propose a view-based indoor/outdoor navigation method as an extension of the view-sequence navigation. The original view-sequence navigation method uses the template matching method with normalized correlation for localization. Because the matching method is sensitive to local illumination changes, it is only used for indoor environment. In this paper, we propose to adopt the accumulated block...
Living organisms have various kinds of flexibility and robustness which are realized by ldquoyuragi,rdquo or biological fluctuations or noises. Bacterial motion is an example of the noise-based motion, since they can move towards higher concentration of some chemical which they prefer although they have only a limited 1 DOF for mobility using that flagella. Bacteria also have only a limited sensory...
Biologically inspired techniques have been widely investigated for realizing adaptive searching behaviour in a mobile robot. In this paper, we propose a framework based on ldquoYuragirdquo, a Japanese word for biological fluctuation. Yuragi-based framework is simple, has a noise-utilizing novelty to keep the robot searching for the goal, while its basic expression enables the robot to switch elegantly...
This paper presents a mobile robotic system for human assistance in navigation-the robot navigates by receiving visual instructions from a human being and is able to replicate them autonomously. We describe three generic components defined as the HOST, the VISION, and the CONTROL components as well as their integration in our teachable mobile robot. These components are connected to each other via...
