This paper addresses the problem of map matching for robot navigation. We propose 3D map matching by a modified RANSAC algorithm for line edges acquired by a stereo camera. 3D map-matching has proven to be successful in indoor and outdoor environments.
In this paper, we present a system of patient robot developed with the aim at improving abilities of nursing student's medical treatment, such as injection to vein. We propose to realize variable emotion of patient robot by using chaos orbit of non-linear time-differentiation equation. To evaluate the effectiveness of the robot through actual injection training, we measure heartbeat rate of nurse...
We are developing a guide robot and an autonomous small vehicle to assist the visually impaired person and the aged. Various functions for support are installed in the guide robot, especially, obstacle avoidance functions necessary to ensure the safety of the user. When the guide robot is moving, the avoidance of not only the static objects but also moving objects is necessary. As the guide robot...
Accessing information when we are on the move is a key feature if mobile computing environments, and using an optical see-through head mounted display (HMD) is one of the most suitable ways to do this. Although the HMD can display information without interfering with the user's view, when the sight behind the display is too complex or too bright, the information displayed can bee very difficult to...
We consider a problem about navigation of a mobile robot with a camera in indoor environment. A new visual control method using a vanishing point of parallel lines at both sides of the corridor is introduced, and we call this the vanishing point visual control method. This method gives a lot of useful information on the design. Therefore we canpsilat need a priori information except both widths of...
We are studying an intelligent perceptual information processing system in which plural processing can run in parallel. Our proposed mathematical activation-input-modulation (AIM) model controls each execution frequency of plural processing independently based on degrees of stimuli detected by external sensors. When external stimuli are detected by some of external sensors, information processing...
