Mobile and/or autonomous robots represent a widely approached research subject. The most common problems associated to all the types of mobile robots refers to the spatial orientation system and to the mathematical models. Additionally, many difficulties are generated taking into consideration practical aspects of implementation, but the technology evolution made possible to develop smaller siz...

This paper describes an autonomous deployment and restoration of a Wireless Sensor Network (WSN) using mobile robots. The authors have been developing an information-gathering system using mobile robots and WSNs in underground spaces in post-disaster environments. In our system, mobile robots carry wireless sensor nodes (SN) and deploy them into the environment while measuring Received Signal S...

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 work aims to give an overview about the current research concerning mobile robots in smart environments. It is part of the motivation of a paradigm that aims to shift complexity away from mobile machines into the (smart) environment without sacrificing the safety of the overall system. Several results of current and ongoing research will be presented, including a powerful simulation enviro...

Collective movement of mobile robots is the problem of how to control a group of robots making them move as a group, in a cohesive way, towards a common direction. Collective movement serves not only to move a group of robots from one point to another, but to perform more complex tasks such as using the group of robots as a moving sensor array, collective mapping and searching tasks...

A control scheme for dynamic tracking of mobile robots is presented, which integrates a velocity controller based on backstepping techniques and a torque controller based on improved RBF neural networks. The proposed torque control strategy derived from sliding modes depends on the dynamics of mobile robots. Because of the uncertainties in robot dynamics, the robustness of the system cannot be ...

In a hybrid wireless sensor network with mobile and static nodes, which have no prior geographical knowledge, successful navigation for mobile robots is one of the main challenges. In this paper, we propose two novel navigation algorithms for outdoor environments, which permit robots to travel from one static node to another along a planned path in the sensor field, ...

This paper presents a new collision avoidance technique, called cooperative collision avoidance, for multiple mobile robots. The detection of the danger of collision between two mobile robots is discussed with respect to the geometric aspects of their paths as are cooperative collision avoidance behaviors. The direction control command and the velocity control command for the cooperative collis...

Robots have bodies, and bodies must obey the laws of physics. The behaviour of a mobile robot is the result of the physical interaction of the robots body and its working environment. In this talk I will introduce mobile robots and show how we design robot bodies. A powerful new approach is called evolutionary robotics. Inspired by Darwinian evolution it is a method for artificially evolving a ...
