In this proposed method, the tracking and mapping procedures are split into two separate tasks and performed in parallel threads. In the tracking thread, a ground feature-based pose estimation method is employed to initialize the algorithm for the constraint moving of the mobile robot.

Robotic mapping is a discipline related to computer vision [1] and cartography. The goal for an autonomous robot is to be able to construct or use a map outdoor use or floor plan indoor use and to localize itself and its recharging bases or beacons in it.

Introduction to Mobile Robots Navigation, Localization and Mapping

Robotic mapping is a discipline related to computer vision [1] and cartography. The goal for an autonomous robot is to be able to construct or use a map outdoor use or floor plan indoor use and to localize itself and its recharging bases or beacons in it.

Evolutionarily shaped blind action may suffice to keep some animals alive. For some insects for example, the environment is not interpreted as a map, and they survive only with a triggered response. A slightly more elaborated navigation strategy dramatically enhances the capabilities of the robot. Cognitive maps enable planning capacities and use of current perceptions, memorized events, and expected consequences. The robot has two sources of information: the idiothetic and the allothetic sources.

When in motion, a robot can use dead reckoning methods such as tracking the number of revolutions of its wheels; this corresponds to the idiothetic source and can give the absolute position of the robot, but it is subject to cumulative error which can grow quickly. The allothetic source corresponds the sensors of the robot, like a camera, a microphone, laser , lidar or sonar.

This means that two different places can be perceived as the same. For example, in a building, it is nearly impossible to determine a location solely with the visual information, because all the corridors may look the same. The internal representation of the map can be "metric" or "topological": [6]. There are three main methods of map representations, i. These employ the notion of a grid, but permit the resolution of the grid to vary so that it can become finer where more accuracy is needed and more coarse where the map is uniform.

Map learning cannot be separated from the localization process, and a difficulty arises when errors in localization are incorporated into the map.

An important additional problem is to determine whether the robot is in a part of environment already stored or never visited. Path planning is an important issue as it allows a robot to get from point A to point B.

Path planning algorithms are measured by their computational complexity. The feasibility of real-time motion planning is dependent on the accuracy of the map or floorplan , on robot localization and on the number of obstacles. Topologically, the problem of path planning is related to the shortest path problem of finding a route between two nodes in a graph. Outdoor robots can use GPS in a similar way to automotive navigation systems. Alternative systems can be used with floor plan and beacons instead of maps for indoor robots, combined with localization wireless hardware.

Localization and mapping are the essence of successful navigation in mobile platform technology. Localization is a fundamental task in order to achieve high levels of autonomy in robot navigation and robustness in vehicle positioning. Robot localization and mapping is commonly related to cartography, combining science, technique and computation to build a trajectory map that reality can be modelle Robot localization and mapping is commonly related to cartography, combining science, technique and computation to build a trajectory map that reality can be modelled in ways that communicate spatial information effectively. This book describes comprehensive introduction, theories and applications related to localization, positioning and map building in mobile robot and autonomous vehicle platforms. It is organized in twenty seven chapters. Each chapter is rich with different degrees of details and approaches, supported by unique and actual resources that make it possible for readers to explore and learn the up to date knowledge in robot navigation technology.

This chapter can be considered as an introduction to mobile robotics. This chapter covers a brief mathematical description of mobile robots that consists of kinematic and dynamics with nonholonomic constrains applied to wheeled robots. Then, a terrain representation and mapping survey has been conducted. After that, the path planning study was performed. It includes a planner definition and several approaches to navigation, which are divided by different behaviors and types of world representation. The last part is dedicated to localization approaches and covers the local incremental method and global localization techniques.

Graph-based robust localization and mapping for autonomous mobile robotic navigation Abstract: Simultaneous Localization and Mapping SLAM means to estimate the positions and orientations of the mobile robot and to construct the model of the environment, essential and critical for autonomous navigation and widely used in a large range of application fields, the research goal is to design, implement and validate graph-based robust SLAM algorithm in indoor office-like dynamic scenarios. On the local level, scan matching is executed to estimate the local-relative-roto-translation value: first, pre-processing is performed to filter out the parts corresponding to the moving objects in the raw LIDAR data; second, conditioned-hough-transform-and-linear-regression-based line-segment detection is accomplished to detect the line features from the rest of LIDAR data; third, matching by fitting point to line is applied to estimate the roto-translation value. On the global level, the topological graph is constructed with the previously estimated motion constraints and batch optimization is achieved by a linear solution to estimate the global robot trajectory. Meanwhile, for the local line-feature maps which includes information about the static environment, they are transformed to the global frame based on the robot-pose information and integrated to construct the global-line-feature map.

Simultaneous localization and mapping SLAM is the process by which a mobile robot can construct a map of an unknown environment and simultaneously compute its location using the map 1.

As mobile robots become more common in general knowledge and practices, as opposed to simply in research labs, there is an increased need for the introduction and methods to Simultaneous Localization and Mapping SLAM and its techniques and concepts related to robotics.
