Robot navigation has been a hot topic in the area of mobile robot. A lot of research has been undergone ranging from noble algorithms to applications. Fisheye image has wide angle View and it is easy to obtain the position of the object and keep it in vision within large scale, so it is an important research domain in robot navigation. However it has a disadvantage that the image obtained from fisheye...
This paper presents a monocular vision and odometer based SLAM algorithm, making use of a novel artificial landmark which is called MR (Mobile Robot) code. A brief introduction of MR code system is given. A practical error model for odometric position estimation is described and the parameters are determined through experiments which verify the rationalities of the model. During robot motion, the...
This paper presents a practical topological navigation system for indoor mobile robots, making use of a novel artificial landmark which is called MR (Mobile Robot) code. This new kind of paper-made landmarks can be easily attached on the ceilings or on the walls. Localization algorithms for the two cases are given respectively. An approaching control algorithm and an extended line tracking algorithm...
