Fiducial markers enable reliable service robot control. In human-robot coexistence environments, efficient placement of square or circular markers can be challenging due to limited space. In this study, we developed a world-first, elongated fiducial marker, capable of high-accuracy 6-DoF measurement…
To extend the coverage of people able to receive high-quality rehabilitation, remote rehabilitation is required in addition to traditional face-to-face rehabilitation. Although remote rehabilitation using video conferencing systems has been realized to date, communication through physical sensations…
Lenticular angle gauge (LEAG) is a planar pattern that visualizes relative attitude by the position of the black line, which moves according to the viewing angle. The authors developed a new LEAG in which the direction of movement of the black line is 90◦ different from the previous LEAG, and used i…
Technologies for estimating self-position and orientation are important for both humans and robots. These technologies allow robots to perform tasks such as carrying objects and allow people to reach their destinations. Although self-position estimation technologies using GPS and laser rangefinders…
Indoor positioning technology is essential for indoor mobile robots and drones. However, there has never been a general-purpose technology or infrastructure that enables indoor positioning with an accuracy of less than 10 cm. We have developed an attitude measurement method using multiple dynamic mo…
Automatic control of mobile robots and robot arms requires techniques for estimating the position and orientation of objects with high accuracy and robustness. Although methods using markers or machine learning have been developed, general-purpose and highly accurate estimations have not been realiz…
Visual markers are useful tools that aid autonomous robots in object recognition and pose measurement; however, conventional markers have two fundamental problems in orientation estimation: (1) inaccurate estimation in the frontal direction and (2) pose ambiguity. We previously developed a visual ma…
In this paper, a robotic wheelchair using only a pan-tilt-zoom camera is proposed for developing a robotic system which enables a user to navigate in complex environment at low cost. For realizing the proposed system, a high accuracy visual marker, LentiBar which is capable of achieving a high level…
