In recent years, robots working in human living space are increasing with development of robot technologies. Environmental information acquisition and human estimation are necessary to control the robots moving in this kind dynamic environment. In this study, we proposed a map generation method which can comprehend dynamic environment with SLAM technology. During the information acquisition of dynamic...
RFID (Radio Frequency IDentification) systems have become meaningful as a new identification source that is applicable in ubiquitous environments. Each RFID tag has a unique ID, and is attached to some object. A user reads the unique ID of a RFID tag with RFID readers and obtains the information on the object. One of the important technologies that use the RFID systems is the indoor position estimation...
In order to realize intelligent agent such as autonomous mobile robots, reinforcement learning is one of the necessary techniques in behavior control system. However, applying the reinforcement learning to actual sized problem, the ??curse of dimensionality?? problem in partition of sensory states should be avoided maintaining computational efficiency. In multi-agent reinforcement learning, the problem...
This paper presents a novel camera calibration method for a system consists of a sensor-less mobile robot and an external camera. This method can estimate the focal length and the viewing direction of the camera relative to a plane where the sensor-less mobile robot moves from a single image of an arbitrary circle on that plane. Since it is easy to let a four-wheel mobile car to move along a circular...
The RFID (radio frequency identification) tag is expected to be used as a tool of localization. With the localization of RFID tags, a mobile robot with an installed RFID reader can recognize the surrounding environment. In addition, it can be applied to a navigation system for walkers. In this paper, we propose a new scheme named communication range recognition (CRR) in order to localize RFID tags...
Home use robots and service robots have been expected for the society of the aging and the falling birthrate. However, a lot of disturbance avoiding the robot's activities exists in such an environment. Universal Design with Robots (UDRobtrade) has been proposed to cope with these problems in our daily life environment using the concept of universal design. Here, interface designs for mobility, handling,...
In order to realize intelligent agent such as autonomous mobile robots, reinforcement learning is one of necessary techniques in behavior control system. However, applying the reinforcement learning to actual sized problem, the ldquocurse of dimensionalityrdquo problem in partition of sensory states should be avoided maintaining computational efficiency. Furthermore the robot task is desired to be...
The RFID (radio frequency identification) tag is expected as a tool of localization. By the localization of RFID tags, a mobile robot which installs in RFID readers can recognize surrounding environments. In addition, it can be applied to a navigation system for walkers. In this paper, we propose an adaptive likelihood distribution scheme for the localization of RFID tags. This method adjusts the...
