In order to make effective works with the mobile robot and maximize its working performance, it is necessary to estimate and track the current pose of the mobile robot. In this paper, under the assumption that the initial pose, kinematics and environmental model of a mobile robot are known, the localization and tracking of the mobile robot's position and orientation have been carried out. The odometry model with the problem of accumulation of unlimited errors is used for tracking the pose, and sensor fusion algorithms are applied to solve this problem. By using the odometry and laser range finder model, the Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), Unscented Information Filter (UIF), Extended Information Filter (EIF) algorithms were tested on a graphical user interface (GUI) based on occupancy grid maps as an environment model, respectively. In this context, the pose tracking and estimation performances of the non-linear model based estimators are compared to each other. Since occupancy grid maps are utilized, only the laser range finder measurement uncertainty should be considered unlike feature based maps. In this way, the computational complexity can be reduced. When the simulation results are evaluated, it is determined that the Extended Information Filter algorithm has expressed more stable performance in terms of the mobile robot pose estimation.

Mobile robot navigaiton is an important task for the operations of the mobile robots. Due to the wheel slippages, performance of the dead reckoning in estimating speed of the robot and the position of the robot is not sufficient. To overcome the errors in navigation estimates, usage of the recurrent deep neural networks is porposed. Neural networks are used to understand the behaviour of the linear and nonlinear systems. Since wheel-ground interaction will be modeled with non-linear models and the estimatin...
Vision-based robot localization using artificial and natural landmarks
Arıcan, Zafer; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2004)
In mobile robot applications, it is an important issue for a robot to know where it is. Accurate localization becomes crucial for navigation and map building applications because both route to follow and positions of the objects to be inserted into the map highly depend on the position of the robot in the environment. For localization, the robot uses the measurements that it takes by various devices such as laser rangefinders, sonars, odometry devices and vision. Generally these devices give the distances o...
DEVELOPMENT OF A SOCIAL REINFORCEMENT LEARNING BASED AGGREGATION METHOD WITH A MOBILE ROBOT SWARM

In this thesis, the development of a social, reinforcement learning-based aggregation method is covered together with the development of a mobile robot swarm of Kobot- Tracked (Kobot-T) robots. The proposed method is developed to improve efficiency in low robot density swarm environments especially when the aggregated area is difficult to find. The method is called Social Reinforcement Learning, and Landmark-Based Aggregation (SRLA) and it is based on Q learning. In this method, robots share their Q tables ...

Mobil robotların arazi şartlarında ihtiyaç duyulan hareketlilik ve performansı gösterebilmeleri için, bacaklı tasarımların yüksek potansiyele sahip oldukları bilinmektedir. Buna rağmen, gerek bacaklı hareketin matematiksel modellenmesi ve denetimindeki, gerekse bu yapıya sahip robotların güvenilir, dayanıklı ve yüksek performanslı olarak tasarlanmalarındaki zorluklar bu alandaki gelişmelerin yavaş ilerlemesine sebep olmuştur. Bu kapsamda yaygın olarak kabul görmüş olan Yaylı Ters Sarkaç (YTS)...
