Most human interactions with the environment depend on our ability to navigate freely and to use our hands and arms to manipulate objects. Developing natural means of controlling these abilities in humanoid robots can significantly broaden the usability of such platforms. An ideal interface for humanoid robot teleoperation will be inexpensive, person-independent, require no wearable equipment, and...
In this paper we propose a new algorithm for relative pose estimation between two images based on a new decomposition for an homography matrix faster than the classical solutions. We introduce in our method approximate information about the planes in the reference images but this additional information allows the decomposition to avoid the multiplicity of solutions. An exhaustive analysis of the error...
Landmark recognition is identified as one important research area in robot navigation systems. It is a key feature for building robots capable of navigating and performing tasks in human environments. However, current object recognition research largely ignores the problems that the mobile robot context introduces. We developed a landmark recognition system which is used by a humanoid robot to identify...
In this paper, we present a complete framework for autonomous indoor robot navigation. We show that autonomous navigation is possible in indoor situation using a single camera and natural landmarks. When navigating in an unknown environment for the first time, a natural behavior consists on memorizing some key views along the performed path, in order to use these references as checkpoints for a future...
Monocular vision based navigation method has the merits of simple computation and cheap hardware and is promising to realize real time navigation. A monocular vision based navigation method for a mobile robot moving in unknown environment is presented in the paper. By a special installation of a monocular camera on the top of a mobile robot, the method can realize the obstacle detection, distance...
Recently, many vision-based navigation methods have been introduced as an intelligent robot application. However, many of these methods mainly focus on finding an image in the database corresponding to a query image. Thus, if the environment changes, for example, objects moving in the environment, a robot is unlikely to find consistent corresponding points with one of the database images. To handle...
Several issues still need to be unraveled in the development of multiagent systems equipped with global vision, as in robot soccer leagues. Here, we underscore three of them (1) real-time constraints on recognition of scene objects; (2) acquisition of environment knowledge; and (3) distribution and allocation of control competencies shared between the repertoire of the agentpsilas reactive behavior,...
This paper presents a Web-based remote laboratory that gives remotely located students the opportunity to experiment different navigation algorithms on a mobile robot connected to Internet. The e-learning system consists of a Web interface that allows uploading the program to the mobile robot, access the on-board video camera and monitor different state variables.
In many mobile robot application, navigation is a critical issues. This paper deals with the localization and building problem in an unknown indoor environment. We propose an exploration based on the use of the sensorial data provided by one CCD camera and odometer system. In this paper, the first part of our study is linked to the problem of Vehicle Model and the algorithm model. The second part...
