ROS-Intro-Project

This project involves creating a ROS package that uses turtlesim. The objective is to create a simulation where one turtle is controlled by the user (using turtle_teleop_key) and the other turtle follows the controlled turtle without using the tf package. An idea of what this should look like can be seen below where the green turtle is controlled using turtle_teleop_key and the white turtle follows the green turtle.

Goals

A demonstration of what is expected should have taken place in the first software meeting you attend. If you joined after the first software meeting, approach a software lead so they could show you what we expect from you. This project will not only help you understand how to work with ROS, but also how to navigate the ROS wiki and find resources to help you in a project. "Googling" things is probably one of the most fundamental skills of a developer!

Once you finish this project, you will be considered a software team member and be expected to contribute towards AMP's codebase.

Overview

In order to complete this task a basic understanding of ROS is required. You will need to complete the core ROS tutorials to solidify core concepts and understand the ROS packages/nodes you will use in this project (turtlesim, turtle_teleop_key, etc.).

This project was inspired by the intro tf tutorials. Although optional, I would recommend going through these tutorials to gain an understanding of how to solve this problem using tf's. And if you are interested, I would also recommend checking out the other ROS Navigation tutorials as they may also contain some helpful information for this challenge.

The challenge of this project is to replicate the turtle_tf_demo.launch in the intro tf tutorials without using tf! Doing this will allow you to gain a solid understanding of the core concepts of ROS as well as appreciate the role and power of the tf package.

Finally, this project will get you familiar with Git/GitHub, and our code review workflow (PRs). Please consult our GitHub guide and feel free to ask the software leads any questions if you get stuck.
