Look inside

The future of the RoboPrototypes company is in your hands. It’s your first day at the company, which specializes in bespoke robotic solutions. The CEO has asked you to develop a prototype of a mobile robot that will serve drinks to mall food court customers. An important client will decide whether they’ll provide follow-up funding after they see your prototype in simulation. Working with Gazebo 11 and employing ROS best practices, you’ll create a model for a differential drive robot that meets the provided specifications. Next, you’ll simulate the robot, implement a basic teleoperation node for controlling it, and add velocity multiplexing for safety purposes.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

He has experience working with over thirty worldwide clients on such platforms as mobile robots, unmanned boats, industrial robots, and even lawnmowers. In his spare time, Mat is developing the robotics newsletter Weekly Robotics. You can get up to date on his work by following him on LinkedIn or by following his blog.

prerequisites

The liveProject is for programmers familiar with the basics of ROS who would like to simulate a robot. To follow this liveProject you’ll need a computer running Ubuntu 20.04 capable of running Gazebo and be familiar with the following:

TOOLS
  • Git
  • XML
  • ROS2
  • Python
TECHNIQUES
  • Linux basics (installing and building software, working with command-line tools, shell basics, working with multiple terminals)
  • Math (translations, rotations, and coordinate systems)
  • Linear algebra
  • Physics (kinematics and dynamics)

you will learn

In this liveProject, you’ll learn these essential skills for getting a differential drive robot moving in simulation using ROS2:

  • Basics of URDF and XACRO modeling
  • Load a robot model in RVIZ2 and Gazebo 11
  • Send Twist messages to the robot (and some of the safety implications involved)
