This paper investigates the use of dynamic window approach (DWA) to solve the high speed autonomous navigation problem for mobile robots. In this paper, our main interest is to adapt the DWA to a car-like robot Robucar. This latter can moves with high speed. It is characterized also by its bounded steering angle imposed by its mechanical structure which(More)
This paper deals with a problem which is basic to mobile robot navigation in dynamic environments: the perception of dynamic objects. This required as a first step the extraction of mobile objects present in the environment tacking into account the effect of the embedded sensor motion. In the proposed algorithm, the laser data are used in the development of(More)
The automatic place recognition problem is one of the key challenges in SLAM approaches for loop closure detection. Most of the appearance-based solutions to this problem share the idea of image feature extraction, memorization, and matching search. The weakness of these solutions is the storage and computational costs which increase drastically with the(More)
This paper investigates the use of a modified dynamic window approach (DWA) to solve the collision avoidance problem for a bi-steerable mobile robot. In this paper, our main interest is to adapt the DWA to a bi-steerable robot Robucar. This latter can move with high speed. It is characterized by its bounded steering angle imposed by its mechanical structure(More)
In this paper, we investigate the feasibility of building a visual memory for robotics spatial cognition without saving visual information. The proposed approach captures some properties of primate brain and especially the view cells. Our bio-inspired visual memory for cognitive map building consists of two main parts. One part is visual information(More)
