Localization is a fundamental problem for mobile robot autonomous navigation. EKF is an efficient tool for position estimation, but it suffers from linearization errors due to linear approximation of nonlinear system equations. In this paper we describe a position estimation method for mobile robot. Process and measurement equations are linear by appropriately constructing the state vector and ...

This paper illustrates on an approach to control a mobile robot using DTMF tone through the GSM network. DTMF tones to control a mobile robot are generated by pressing the keypad buttons of a GSM mobile which is counted as remote. The robot receives the tones using another GSM mobile stuck with it. The mobile robot perceives the control tone by using a DTMF decoder IC and a preprogrammed microp...

When an autonomous mobile robot acts in constructed environments, a map that has the information about obstacles is necessary for the mobile robot. Even if a map is given, however, the mobile robot cannot start its action without the information of its present location on the map. Therefore, techniques of map generation and self-localization are important for mobile robots. In this paper, we pr...

Path planning in mobile robots must ensure optimality of the path. The optimality achieved may be in path, time, energy consumed etc. Path planning in robots also depends on the environment in which it operates like, static or dynamic, known or unknown etc. Global path planning using A* algorithm and genetic algorithm is investigated in this paper. A known dynamic environment, in which a contro...

The Mobile Robot Programming Lab and the Toy Robots Initiative at Carnegie Mellon’s Robotics Institute both focus on the interaction between humans and robots for the sake of education. This paper describes two specific endeavors that are representative of the work we do in robot education and human-robot interaction. The first section describes the Mobile Robot Programming Lab curriculum desig...

The mobile robot technology occupies a wide space in surgical complex procedure, in particular the da Vinci System [1]. In addition, technological development is increasingly incorporated in our everyday lives. Several robots applications in education are mainly concerned with supporting the teaching of subjects directly related to the mobile robot field, such as mobile robot programming and co...

This paper presents a novel pattern recognition algorithm that use weightless neural network (WNNs) technique.This technique plays a role of situation classifier to judge the situation around the mobile robot environment and makes control decision in mobile robot navigation. The WNNs technique is choosen due to significant advantages over conventional neural network, such as they can be easily ...

The basic idea is to construct a mobile patrolling robot for security and monitoring. For an on-demand robotic system, a location aware module provides location information of objects, users, and the mobile robot itself. The probability-based location aware module is modified to handle RSSI measurements with a maximum of calibration. The resultant location calibration module will be more light-...

In this paper the neural network-based controller is designed for motion control of a mobile robot. This paper treats the problems of trajectory following and posture stabilization of the mobile robot with nonholonomic constraints. For this purpose the recurrent neural network with one hidden layer is used. It learns relationship between linear velocities and error positions of the mobile robot...

Mobile robots are increasingly used in applications as diverse as space exploration, rescue missions, automatic floor cleaning in buildings and factories, and mobile surveillance systems. However, one major challenge encountered in the development of applications involving mobile robots is the limited amount of resources that these devices have at their disposal. Effective use of mobile robot r...
