In this paper, a recurrent neural network is used to develop a dynamic controller for mobile robots. The advantage of the control approach is that no knowledge about the robot model is required. This property is very useful in practical situations, where the exact knowledge about the robot parameters is almost unattainable. The proposed approach has been experimentally tested on an Omnidirectio...

In the future, it’s not difficult to image that we will often come across many autonomous mobile robots traversing densely populated place we live in. In such situation, because the autonomous mobile robots need to carry out their tasks in a place with unknown obstacles, the obstacle avoidance is one of the important functions of the robots. With a view to implementation of autonomous mobile ro...

this paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. fuzzy logic control (flc) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  on the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...

This paper proposes a novel control architecture for mobile printer system based on multi-robot cooperation. Mobile printer system consists of 3 omnidirectional robots, wireless LAN system, graphic user interface(GUI) and one host computer. If users draw a picture in GUI, a host computer commands client robots to reproduce it by drawing the same in very short time. To minimize elapsed time in d...

Described here is a new method for depth estimation using a single omnidirectional visual sensor embedded on an autonomous mobile robot. This work is part of an on-going research project to study the visual guidance of autonomous robots. The method is based on a vertically aligned omnistereo configuration and laws of reflection applied on a geometric optics field. The proposed system yields a c...

In this article a self-localization system for small mobile robots based on inexpensive cameras and unobtrusive, passive landmarks is presented and evaluated. The main contribution is the experimental evaluation of the hybrid field of view vision system for self-localization with artificial landmarks. The hybrid vision system consists of an omnidirectional, upward-looking camera with a mirror, ...

in this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. to this end, the dynamics model of the considered wheeled mobile robot is derived using lagrange equations of motion. then, using adams multi-body simulation software, the obtained dynamics of the wheeled system in matlab software is verified. after that, ...
