I'm going to be (re)building this robot, and I want you to build one for yourself! And if you can't afford the parts, I'll be demonstrating how to do each step in simulation first, so you won't be missing out!

Wow, wish I found this 2 years ago. I decided back then that ROS is to complex and that it would take way too much time to play with this. Meanwhile I watched a few of the "Getting ready to build robots with ROS" playlist and I think I am now ready to follow along. Well ... maybe not in the same order. To prevent me from being distracted having to build parts for the robot, I will start with the hardware build first: frame, motors, encoders, lidar, camera and some (optional) bumpers that I can use as a kind of E-stop during development (I don't want to go home in a bin bag). I collected almost all components over the last few years, including the lidar. So the only thing to say now is "3 - 2 - 1 - Activate" 😁

This is so awesome, I'm with you all the way on this build journey! Is this going to be similar to the Linorobot2 build? currently buying bits to put that together but this seems very similar hardware wise. Thank you Josh!

@ArticulatedRobotics 2 жыл бұрын

Hi Alan, I wasn't actually familiar with the linorobot2, but taking a look you're right it is very similar. It looks like their software package is aiming to be a catch-all to handle a variety of hardware options which is a bolder task than I'm willing to aim for at the moment. I think for someone newish to ROS there is value in taking it step by step as my tutorials will, but if I was just doing this for myself, already being familiar with ROS, that looks like a fantastic package to use. I might even take some inspiration from it as I go about making my improvements!

Nice to see another video from you. This is really an interesting project which will give people a chance to do stuff end-to-end. I'm not sure I want to do the hardware part but very interested in building through Gazebo and using ros2_control. How many videos have you planned? How often do you think you can publish one? While I wait for yours, are there other channels that have done something similar?

@ArticulatedRobotics 2 жыл бұрын

Thanks Deepak! There'll be roughly one video per step on that overview page (although I suspect the bit with ros2_control might be spread over a few videos). And after that there'll probably be a couple of extras, so maybe 17 or so in total. Since they take a bit of time to make and I have to squeeze it in around work, I'm going to aim for every 2 weeks although I can't guarantee I'll manage that. I know that means the good stuff is still a while away... Unfortunately I haven't really found much similar out there - that's why I've done it!

@ArticulatedRobotics 2 жыл бұрын

Thanks! I would strongly recommend jumping straight into ROS 2 as a beginner. ROS 1 is not receiving any more updates so there is no point learning something that is outdated (even though there are more tutorials and packages around for it). Not to mention that ROS 2 is just better! If someone really wanted to use ROS 1 then most of the concepts in the tutorials will still apply, just some of the commands and parameters are a bit different.

@ArticulatedRobotics 2 жыл бұрын

Great question! I should probably clarify that in one of the upcoming videos, I've alluded to it in my "Getting Ready to build Robots with ROS" series. To maximise cost and power efficiency I've gone with a "mobile + base station" structure. So the Pi is only running nodes to read data from the sensors and control the motors. All of the perception and planning algorithms are run on a separate "base station" PC (typically the same machine that is used for development). ROS makes it super easy to communicate between the two devices, and if I ever swapped to a more powerful onboard PC, very little would need to change to run it all on there.
