Prerequisites

Simulated Robot Used

Neobotix MP-400 Simulation

The MP-400 can be used in more ambitious applications as an autonomous carrier of special equipment or as an experimental system in robotics research, the MP-400 masters almost all tasks, also with full ROS support.

Syllabus

Unit 1: Understanding Launch Files in ROS2

Understand launch files in ROS2 and explore different methods of creating launch files

What will you learn in this unit:

Call other launches inside the main launch
How to create more complex launch files
Different languages that are supported
launch_ros Actions
Parameter passing

Unit 2: ROS2 Parameters

Learn how to work with Parameters in ROS2.

Topics covered in this unit:

Create a demo code
Interact with parameters from the command line tools
Examine the code
Load parameters on launch file
Parameter Calbacks

Unit 3: Managing Complex Nodes

Learn about multithreading with ROS2 and callback management

What will you learn in this unit?

How to manage more complex Nodes
Executors
Callback Groups

Unit 4: Quality of Services (QoS) in ROS2

Understand how QoS is used in ROS2 with simple examples. You will learn:

How to change them and QoS Compatibility
QoS in ROS2 Bags

Unit 5: Understanding DDS in ROS2

Understand DDS in ROS2 , how to modify it, and how to work with QoS.

What will you learn in this unit?

Understanding DDS in ROS2
Basic use of RVIZ2 debugging tools
view_frames tool
ROS2 Doctor

Unit 6: Lifecycle Nodes

In ROS2, there are two types of nodes:

Nodes that inherit from ‘Node()’
Nodes that inherit from ‘LifecycleNode()’

This unit is about the last one: why you need them and how to use them.

What our students think

“I am wholeheartedly grateful for this outstanding opportunity. I wouldn’t have found a better ROS beginner-friendly course elsewhere. Thanks, ConstructSim !“

Francois Gonothi Toure

“I have tried to start learning ROS before and that was so difficult because I didn’t understand how to start, now with these introductory courses I am very excited because I can finally start to enter this world.“

Daniel Martínez

“I really enjoy the practical aspect and learning by doing. I feel like I learn way faster and with a rich understanding.”
