Man, this corner of KZread right along with Ben Eater and 3brown1blue channels are among the best

I agree, these three channel is the holy grail.

Love the extra effort in addressing the drifting problem not only in a theoretical way, but showing this in an (un)practical scenario.

Your channel is a pure bliss. Profound and still condensed knowledge. Are you planning on doing another video on FIR and IIR filtering including the FMAC peripheral of the stm32 MCs?

Thank you very much, Helge! I haven't planned any videos on the STM32's FMAC yet I'm afraid..

I can't wait for the Kalman filter video, because I'm aware of it, and of sensor fusion in general, by quite a long time now.. however this may be the first time that I really understand it, because your explanations are really clear and to the essentials!! Thank you so much for your work!

As someone that does not work in but adjacent to this field these videos are amazing at building knowledge to better communicate and understand this stuff. It really is a gem! Thank you!

Thank you Phil for this informative content. Excited for Part 2!

You're life changer Engineer Phil, I appreciate your wonderful contents,

Thank you for these. The quality of information is incredible.

So happy I found your channel! Thanks so much, keep up the great work!

mate this channel was an instant sub in the first couple minutes

Really great series, this is such a useful resource for some IMU experiments I am planning!

THIS IS AMAZING!!! Looking forward for the next video and super excited!!!

What a happy coincidence! I had just started to look for educational content on sensor fusion this week.

Really nice presentation, thank you! Sensor fusion is a wonderful rabbit hole where one can spend all time until retirement if need be ;) It would be very nice if you would include quaternion-based solutions as well. With modern processors, that is a viable route that offers some very interesting possibilities. Good luck and happy fusioning!

What I'd like to see more of is fusion with a structural model of the vehicle and MEMS combos at multiple points on the structure.

Great content Phil - looking forward to the filters video. It would be useful if you could include commentary on additional sensors (e.g. magnetometer for yaw , thermal horizon sensing for pitch and roll).

Thank you very much, Mike! Yes, I'll touch on using a magnetometer for heading estimation when we come to the EKF!

Great theoretical and practical explanation :) ! do you practical advantages in using quaternions for attitude estimation?

Thanks for the video. This is gold.

Great video! I am really interested in learning all about IMU and all the implementation methods. I would like to really understand how everything works but even If I am an engineer I feel that I need to re-study everything again. Could you please recommend me some good technical books for learning about this? Thank you!

Thank you for this video, im greatly looking forward to this series. Have you looked into the Madjwick filter, it seems like it's less computationally expensive than the EKF Also do you plan on making a video on integrating the attitude estimates with GPS?

@PhilsLab

2 жыл бұрын

Thank you! I've played around with the Madgwick filter but wasn't happy with the performance and expandability in comparison with an EKF, although it is less computationally expensive. I'll probably add in IMU-based GPS-smoothing in a future video (not this series however, as this'll just cover the basics).

Interesting topic!

that's what I'm working on it these days, great 👌. I'm implementing imu to achieve yaw. i set it on my desired point and set it to zero, then when i rotate that it gives me a good yaw at the first rotation but after that it start the random walk and drifting the system, i don't know how to solve it. in this case i dont use magnet

This is very cool!!!

The formula you used at 10:44 was seen in many articles, all of which uses “plus” quadcopter setup to mathematically model. But I always wonder if plus setup and X setup would be the same, or if I could use their result for an X quadcopter. If not, why use plus, while X is more practical.

Do you recommend a book with all these topic in this amazing platical way?

Awesome!

thanks mate

Sorry, this may be a stupid question that you have already answered somewhere as I came across this series recently. Is there a reason you did not use BNO055 that implements some of these algorithms at hardware level?

I'm getting a NaN when acc_x is greater than 9.81, because sin^-1 of something >1 is a Mathematical error, so I was wondering if it is due to my accel sensor reading or maybe the pass low filter or I have to declare a constraints? Btw, terrific tutorial, thank you a lot.

Could you make a video on pcb design of nb iot modules

It is quite nice to see somebody hearing me ! (I've cited this topic in the previous posts ) great content and very appreciated! Btw if you enlighten the gimbal lock issue after this fusion topic, it will be very appreciated. thanks in advance.

Time varying bias term -> drift.

can i have the references for the IMU's model?

Do you have books in this field?

Watched the entire video for sensor fusion only to find at the end that sensor fusion is in the upcoming video. 😭
