Learning Robotics using Python - Second Edition

By: Lentin Joseph

Overview of this book

Robot Operating System (ROS) is one of the most popular robotics software frameworks in research and industry. It has various features for implementing different capabilities in a robot without implementing them from scratch. This book starts by showing you the fundamentals of ROS so you understand the basics of differential robots. Then, you'll learn about robot modeling and how to design and simulate it using ROS. Moving on, we'll design robot hardware and interfacing actuators. Then, you'll learn to configure and program depth sensors and LIDARs using ROS. Finally, you'll create a GUI for your robot using the Qt framework. By the end of this tutorial, you'll have a clear idea of how to integrate and assemble everything into a robot and how to bundle the software package.

Creating 2D CAD drawing of a robot using LibreCAD

We will take a look at the basic interface of LibreCAD. The following screenshot shows the interface of LibreCAD:

LibreCAD tool

A CAD toolbar has the necessary components to draw a model. The following diagram shows the detailed overview of the CAD toolbar:

A detailed description of LibreCAD tools is available at the following link:

Here is a short explanation of each tool:

  • Command Box: This is used to draw figures by only using commands. We can draw diagrams without touching any toolbar. A detail explanation about the usage of the Command Box can be found at:
  • Layer List: This will have layers used in the current drawing. A basic concept in computer-aided drafting is the use of layers to organize a drawing. A detailed explanation of layers can...
