A successful and efficient robot navigation method in dynamic environments requires predicting that the unce...

This paper addresses the issue of the autonomous mobile robot (AMR) navigation task based on the hybrid control modes. The novel hybrid control mode, based on multi-sensors information by using the fuzzy approach, has been presented in this research. The system operates in real time, is robust, enables the robot to operate with imprecise knowledge, and takes into account the physical limitation...

Supervisory control of the mobile robot navigation system has critical importance. The supervisory control software development of mobile robot navigation can be performed in an unknown environment or for controlled robots in a known environment. Finite automata and graph theory are functional tools in modeling the robot navigation system through discrete environment. This research has emphasis...

One of the main goals of a household robot is to navigate in an environment in a safe way. Some prior work has addressed this assumption by using dead reckoning in combination with reactive behaviours to interact with unknown dynamic environment. This paper presents a mobile robot navigation system that uses a topological landmark based representation of the environment from which it is possibl...

The aim of this paper is to briefly describe proposed algorithms for an autonomous mobile robot. These algorithms concern data processing from sensors, description of environment from these data and finally navigation on these data. Results from these processes are based on simulation of real mobile robot system. On proposed algorithms can be showed principle of ultrasonic and infrared sensor, ...

This paper addresses a new architecture that employs optical flow for vision based obstacle avoidance problem for mobile robot navigation. The proposed architecture utilizes monocular vision for navigation and obstacle avoidance. Real experiments to guide a Pioneer 3-DX mobile robot in indoor environments are presented, and the analysis of the results allow us to validate the proposed behavior ...
