In order to successfully navigate mobile robots in an unknown environment, an appropriate navigation strategy must be employed. Such a strategy certainly relies on an effective navigation map based on which robot trajectories can be well planned. The navigation map can be built based on a sparse map constructed by a visual simultaneous localization and mapping (VSLAM) algorithm. This paper presents...
In this paper, a vision-based helper robotic system is proposed that can help the elderly in household environments. Specifically, a mobile robot equipped with an onboard camera is capable of following the elderly. The system can visually identify the elderly by using Camshift algorithm and thus determines appropriate commands to drive the mobile robot to follow the elderly. A practical function of...
Most of the recent research on autonomous mobile robotics is focused on obstacle detection and path planning in unknown environments. Improved accuracy in environment recognition and high precision in robot control can ensure feasibility of intelligent and autonomous mobile robotic systems in unexplored environments. To reach this goal, effective navigation and control approaches for the mobile robots...

This paper proposes a novel diminishing-reality-based AR registration, called DR-marker. It is used in our proposed filmmaking system ARFMS. Although it is based on marker-based registration method, the user will not see the special marker in the real environment via diminishing reality technology. Users can apply the DR-marker just like real scene element, because it takes the advantages of marker-based...
