**************************************************************************************
Practical Robotics in C++ teaches real robotics without the reader needing a university degree to follow the tutorials. Topics covered include:
Choosing and setting up a computer for robotics
Electronics for Robotics
Buying, building, and hacking robots
Motors: Different types, how to control them
Communications with sensors and other devices
Robot control theory and controller design
Mapping and Autonomous Path-Planning
Autonomous motion
Robot tracking and localization
Sensors for robotics
Computer Vision
Sensor Fusion
Final project: Build and program a complete autonomous robot!
As of May 3, 2020 Practical Robotics in C++ is at the publisher for final editing and formatting and is expected to be available for purchase very soon. Please follow practicalrobotics and this KZbin channel for the official announcement and links.
Thanks to crappypictures.com for the technical difficulties image.

This kind of summary/overview is very useful, but it is mostly missing from the official ROS tutorials. Thanks for the video!

[@PracticalRobotics]

Glad it was helpful!

[@markusmitph8987]

Thank you so much!! You safed my bachelors thesis!! :D

[@ballajaisheel1120]

can you please tell ..... i have been facing a problem from the map_updates my lidars are not updating simultaneously lase_scan is working but there is no updation in rviz2

[@teetanrobotics5363]

My Dream Channel. Eagerly waiting for the book. Please let me know where is it

[@PracticalRobotics]

I'm eagerly wating myself! The publisher has just assured me that it is the final stages - getting the covers ready and doing the final page layout, etc. I hope to be able to provide links by next week!

[@kerron_]

Glad i found this

[@PracticalRobotics]

Very happy that you found it useful.

I would like to ask how do I add hector slam into the practical robotics in C++ project cuz i dont have wheel encoder but i have lidar instead

[@PracticalRobotics]

Hi. That's a great request and I'll add this somewhere near the top of videos to make, but with the an autonomous robotics competition coming up it may not be soon enough for you. Off the top of my head I I would start with re-writing simple_diff_drive.cpp to calculate actual velocity based on sequential odometry messages (getting the odometry from HectorSlam) instead of the encoder data. Hope that helps in the meantime - good luck and please share what you learn at the practical robotics group! facebook.com/groups/practicalrobotics/

[@clementc9938]

@@PracticalRobotics thx for your information. Will definitely comment what i have learned. Hope to watch your new video as soon as possible!

[@averageengineeer]

Awesome video, thank you! I am having a problem; my turtle bot is running inside a docker container. I know i can run a GUI inside a container but I want to run rviz on the host-machine to vizualize. How can I do this ?

[@PracticalRobotics]

That's a good question. I don't *think* you can pass messages from the container to the host machine, but I don't use Docker so I could definitely be wrong about that. If it possible, I imagine it's much like how we network computers where we make the one the ROS master and others are the slave devices. For example I can use my robot with a raspberry pi to publish messages and I usually use my laptop to run RVIZ or image recognition routines because they slow the PI down quite a bit. Check out my video here for how to do that kzbin.info/www/bejne/fWLKdaOjg9ZqiJo. Hope it helps!

@@PracticalRobotics thank you, it works

[@razidaufaa9626]

Excuse me sir, I want to ask, how do I change the length and width values ​​on the map? because i change it can't be edited. Thank you sir

[@PracticalRobotics]

I'm not certain what you mean. ..The map is edited by the software that generates it, rviz is just to visualize it.

[@juliettepepper7137]

Could you show me the steps that I need to follow to connect a Pepper robot with Rviz and see it? I've just using ubuntu 18.04 with Ros melodic.

[@PracticalRobotics]

Pepper looks really neat but I'm afraid I don't know anythng about that particular robot. I would check with the manufacturer - it is possible it doesn't use ROS at all, and they may have tools ready for you to use.

[@jksammyken24ify]

Hmmm as much as i wanted to understand your tutorial, i just still dont get it. 😁

[@PracticalRobotics]

I'm sorry to hear that! Are you currently using ROS and familiar with topics and message traffic?

[@mohankrishnan2022]

You need to speak a little bit louder and enunciate your words clearly. When your volume drifts low, it is hard to understand what you are saying!
