Dude! You've managed to make my tiny brain understand the concepts of IMU drift and bias. Kinda knew this stuff through empirical results, but it's fantastic to have it explained, with some equations which make sense now, but never made sense to me over 30 years ago. Thank you!
I learned so much more from your video than from all the other websites and videos I've seen in the last month. thank you so much for making this concept a lot easier😍
Please don't downplay yourself with these ' Nerd' quotes man, we engineers work with technical literature and terms, and it's expected that we may sound a bit out there for people who aren't in that spectrum. I think it's just like in any job, some go by it, and those who enjoy it and learn it to the fullest (geeks). Yes, most of us are geeks, and we need to be if we want to get by in these areas, but being a nerd is just being socially awkward and not knowing how to talk with people with different passions and hobbies. Great video by the way!
Thanks for that video! Very clear and concise. I'm interested in the precision you can acheive with these "hobbyist" sensors. I'll look through your other videos. Edit: Also you mentioned 9-DOf IMUs. Any advantages over the 6-DOF?
IMUs we have access to won't be sensitive enough to measure earth's rotation, but can still yield sufficiently accurate data for hobby applications (like self-balancing robots and drones). 9-DOF IMUs just add on a compass and have the advantage of having three sensors in a small footprint. Thanks for the interest!
@@micwroengr7851 So if i want to measure the angle/position of a joystick would the 9-DOF be more accurate than a 6-DOF? As i understand it the additional magnetometer giving the added 3-DOF only give reference to the earth and the 6-DOF IMU would do the same only difference is that it would not know its orientation in relation to the earth's poles. Is that right?
Discrete filters, such as median or FIR filters, add delay. The filtered signal will lag behind the original noisy signal. Any measurement delays can lead to controller instability. Therefore, any delay in gyro measurements can cause instability and potentially a crash! You can probably get away with VERY LIGHTLY filtering noisy gyro data, but at your own risk. Check out this MathWorks video for a great explanation: www.mathworks.com/videos/control-systems-in-practice-part-4-why-time-delay-matters-1536913253300.html
Its misleading and incorrect to state that the integration of uncompensated gyro bias to angle as "gyro drift". If the gyro bias is not varying, its technically NOT drifting at all. Its better to refer the integration error as heading errors.

Your explanations are great. I really enjoy it. I hope you continue to put out new videos.

Great video by the way!
Marvellously explained all the things related to IMU. Thank you so much.
This is what I was looking for! Thanks a lot man; Really nice explanation for beginners like me.🙂
very good explanation. It was extremely helpful for me, a beginner trying to select a IMU for my project
I love this video. Thank you.
thank you for creating this video! it was such a helpful and easy to understand introduction to IMUs
Wow A new learning language curve. 📜 Thanks.
Really great video, it was clear and help me to much for understanding this theme.
Thanks for the info, man. Really appreciated!
nice explanation! I'm creating a garmin watch app to detect pool laps as a swimmer flips off the wall... using gyro and accel.. this helps!
Great video good luck with your project
Awesome Explanation 👏 Thanks a lot
Really good and clear explanation thanks man way to go! ✌️
You are amazing!
Thanks for giving some starting points. I will research kalman filters )
Hello Michael.
Say me please, how compensation centrifugal force?
Very good video!
wow, great video, thanks a lot :)
Good explanation.
Thank you for that video ! can you talk about 'Attitude estimation on SO(3) based on direct inertial
measurements' ?
Can you make a manned multirotor Flight controller? Everything is designed for unmanned.
Thanks for the video, how can I deactive an IMU?
Excellent video. There's one thing that might be confusing.
9:00 Is it "bias" or "bias stability"?
Just awesome ... could you please explain how tonsetup kalman filter in gyro prediction .It will be much helpful for the community
I want to cover Kalman filters and IMU sensor fusion in the future, so stay tuned!
Will this software use quaternions
cool stuff
well explained
Thank you

@@blind228 There are already very high precision sensors and accelerometers that we can talk about
Hi Engr.!!!What books do you recommend about designing a drone??,By the way im new subscriber from philippines,Thank you :)
you said:"Do not filter the gyroscope measurements", why???
Why should we not filter the Gyroscope data?
Discrete filters, such as median or FIR filters, add delay. The filtered signal will lag behind the original noisy signal. Any measurement delays can lead to controller instability. Therefore, any delay in gyro measurements can cause instability and potentially a crash! You can probably get away with VERY LIGHTLY filtering noisy gyro data, but at your own risk.

Are you using arduino or raspberry pi
my boi made me look dumb lol. subscribed :D

best explanation ;subscribed. I will always follow your videos and let you help me; I am gona do the same as you are doing !!!
are you a teacher
