Please continue this series, extremely helpful to understand such complex topics. Excellent demonstrations! Please upload more videos on this topic

The introduction of extrinsic and intrinsic rotations was really helpful. Thanks.

I remember struggling at University for hours to understand this topic, but with this clear explenation and memorising tips life could have been much easier!

I liked your explanation of 3d rotations, and regarding 2d, I thought SO2.

Please upload more videos on the topic of rotation

I finished my degree that had a focus on robotics in november so this is an awesome refresher. However, the right hand rules you shown jacked my head up, probably because I'm used to the general electronics rules (right hand and left hand) are thumb up and middle finger pointing out, so right hand rule here is exactly the same as left hand rule. I'll have to review my books if they explained it the way you did. They probably did, I just don't remember.

Thank you very much for this video,
I just can't figure out why the sin terms in 1:40 have signs like that, shouldn't it be the inverse? (I think that in counter-clockwise rotation the upper sin is positive and the lower sin is negative).
You can check this wiki page to see:

Im following your tutorial on how to setup ros on computer and raspberry pi, the network setup video is a bit unclear, do i have so give static ip addresses to both the pi and the computer?

Amazing video. What tool was used to make the animation of the angles?

[alexbayarsaikhan]

Thank you for your videos. I really like your mobile robotic series. I'm new to robotics and have a question. What books do you recommend for beginners who want to learn more about ROS 2 with Python?

[THEDOOMSLAYER]

Hello, thanks for the video, would you like to make a tutorial, like you used to make about ros robot, but with robot dog?

hey josh, can you please make a ackerman car tutorial just like last project,
thanks

once again another dude on youtube that thinks everyone coming on here for help are looking for a guy talking learning the theory and the history of robotics, people wanna see how to put shit together, wiring, what kind of controllers to use and watch them build it. they don’t want to go to school on youtube.
