Overview

This submission contains educational tools to help students understand the concept of localization for mobile robots. The lessons include interactive scripts to demonstrate the use of common localization algorithms, landmark-based localization and the Extended Kalman Filter (EKF).

The localization of a robot is a fundamental tool for its navigation. There are localization methods based on different sources of information and hardware components, as there is no method that works properly in any scenario and for any robot. From the educational point of view, few students students are able to understand all the mathematical background involved in the localization process.

Requirements

Lessons:

Be sure you already have the requirements Check Lessons folder to start, the lessons are divided into 6 chapters:

  • Chapter 1 Basics: It Covers all the basics to run simulations and understand the basic kinematics for a differential mobile robot.

Full System

  • Chapter 2 Sensors: At this chapter you will learn how to implement sensors such as Odometry, LIDAR, Object detection and algorithms like VFH for obstacle avoidance.

Full System

  • Chapter 3 Path planning: At this lessons you will learn how to plan a path and how to make the robot follows it (path tracking) using RRT* algorithm.

Full System

  • Chapter 4 Summary of previous Chapters: In this lesson you will learn how to put all together and reduce your code from previous lessons.

  • Chapter 5 Localization: In this chapter you will learn why is necessary a localization system and then you will implement the Extended Kalman Filter understanding the theory of each step. You can find a detailed explanation in the file Lecture_Kalman_filter_robots.pdf in this repository.

Full System

  • Chapter 6 ROS Localization: In this lesson We show you how a localization system works along with MATLAB and ROS. And you will learn how to use the correct EKF parameters using a ROSBAG.

Full System

  • You can practice with different algorithms, maps (maps folder) and changing parameters to practice in different environments and situations.
