How to use IMU with Raspberry Pi

[@cmtro]

Excellent! As usual it is educational, concise and precise.

Hi cmtro! I am glad if this video has helped you!

[@Anatiger.]

Can you use a BNO055 instead of the IMU that you use? If so what can I change in the python code to make it work for the BNO055? Thank you!

[@robotmania8896]

Hi SusDio! Thanks for watching my video! Yes, the code provided with my video should work with BNO055. Please refer to this page to use BNO055 libraries. learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/python-circuitpython

hey i am a little bit confused on how to use mpu9250 with raspberry pi4. i need to use it for keeping track on oriantation of my project rc car

[@robotmania8896]

Hi Akshat Singh! Thanks for watching my video! What problem exactly do you have with mpu9250?

[@djkadakamc1889]

Hi, do you think that signal could be more accurate using a raspberry instead of an esp32 wroom 32??? I need a very accurate X movement signal. Thanks

[@robotmania8896]

Hi Dj Kad aka MC! I have never used esp32-wroom-32, so I cannot tell you for sure, but if the computational capabilities of these two devises are the same, I don’t think that there will be any difference.

[@djkadakamc1889]

Thanks. I think esp32 have enough resource. Probably i should focus on the MEMS chip specs. I'm starting with mpu6050. If i need more accurated signal i will buy a MPU9250 because has better performance. If it's not enough i will buy an expensive ADIS16470. It's a very important project

I got a question: can I use ubuntu os22.04 with imu bno055 this code be active?

[@robotmania8896]

Hi Tân Lê Thái! Thanks for watching my video! I think you can use bno055 with ubuntu22 using this library rpi-lgpio.readthedocs.io/en/latest/ But the code provided with this tutorial is not applicable for ubuntu22.

it shows an error after the "pip3 install imufusion" i don't know why, help please

[@robotmania8896]

Hi Michelle HC! Thanks for watching my video! What kind of error do you have?

[@psamae]

@@robotmania8896 go the same error, it says "ERROR: Could not find a version thta satisfies the requirement imfusion"

[@robotmania8896]

@@psamae I think it could be a python version problem. Which version of python are you using?

[@psamae]

@@robotmania8896 I am on python 3

[@robotmania8896]

@@psamae Which version of python3 exactly? It seems that “imufusion” is provided only from python3.8. pypi.org/project/imufusion/1.0.6/#files

[@JohnBo199]

Great video!! I have one question left tho. What exactly is the difference between a IMU and a MEMS? Do they work together? Maybe you can help me to answer my question to get better understanding. Thanks a lot :-)

[@robotmania8896]

Hi Jonathan Edling! Thanks for watching my video! In my understanding, MEMS itself is a sensor (accelerometer, gyroscope). And IMU consists of several sensors (often MEMS sensors), circuit and a program. I also found an interesting article. I hope it will help you. www.geospatialworld.net/prime/special-features/difference-between-mems-fog-imus/

Thank you! Great article ❤
