This paper presents a model-based control design for trajectory tracking of two-wheeled mobile robots based on Linear Quadratic Regulator (LQR) optimal control. The model proposed in this article has been implemented on a computational model which is obtained from kinematic and dynamic relations of KHEPERA IV. The purpose of control is to track a predefined reference trajectory with the best po...

This paper deals with the tracking control for a dynamic model of a wheeled mobile robot in the presence of some perturbations. The control strategy is based on integral sliding mode. Simulations illustrate the results on the studied mobile robot.

In this paper we propose a sensor-based navigation method for navigation of wheeled mobile robot, based on the Kohonen self-organising map (SOM). We discuss a sensor-based approach to path design and control of wheeled mobile robot in an unknown 2-D environment with static obstacles. A strategy of reactive navigation is developed including two main behaviours: a reaching the middle of a collisi...

The paper addresses three important topics in mobile robotics. These are the path follower, the multi-sensors and the steering fuzzy controllers for wheeled mobile robot. This paper presents a novel computer vision methodology for building a system capable of determining the presence of a path follower, tracking the objects on that path, and recognizing the objects shape in vertical or in horiz...

The subject of this chapter is the control problem for nonholonomic wheeled. Of geometric smoothness is in general noduri alpinism pdf required for nonholonomic robots. Nev.Mobile robots did not wait to know that they were nonholonomic to plan and. Of robot motion planning: as examples, in 1969, the mobile robot Shakey used. From a kinematic point of view, the main characteristic of wheeled rob...

−− A generic kinematic control, which is directly applicable to any type of wheeled mobile robot, is proposed in this work. Firstly, it is presented the kinematic models of the four common types of wheels (fixed, centered orientable, castor and Swedish) a classification of wheeled mobile robots. Afterwards, it is proposed a kinematic control scheme with three nested loops: dynamic, kinematic an...

A modular wheeled mobile robot is composed of autonomous wheeled modules capable of selfassembling to form up a modular mobile robot. The robot can change the number of its modules by having the modules detach themselves from the main body and move independently. In this paper, we propose a docking system for such robots, including a connection mechanism and a docking guidance system. The conne...

Non-systematic errors in wheeled mobile robots are significantly influenced by irregularities on the surface. The presence of non-smoothness on a surface causes the robot to deviate from its desired trajectory, and move towards an undesirable destination. This paper uses a technique, previously proposed by the first author, to alleviate the positional error originating from non-systematic resou...

A wheeled mobile mechanism with a passive and/or active linkage mechanism for traveling in the outdoor environment is developed and evaluated. In our previous research, we developed a wheeled mobile robot which has six wheels and a passive linkage mechanism, and its maneuverability was experimentally verified. The ability to climb over a 0.20 [m] high bump, which is twice height of the wheel di...
