This is very impressive! Thank you for sharing your work on this. I have not had much luck with resolving drift with the mpu6050. But I was not aware of the bno055! It's results appear to be much more stable. I would be very tempted to switch my current project for measuring linear movements from arduino/mpu6050 to esp32/bno055.

The BNO055 has a built in Cortex processor that reads the raw data and runs a sensor fusion algorithm (such as Kalman filter) internally. So your ESP processor is already reading filtered data from it. In the case of the Bosch you really are getting raw data. Thanks for your video in which one can clearly see the difference.

Thanks for this comparison and analysis

Love your Work

Thank you so much for this explanatory video.

Great videos! I'm having some trouble writing the data to the file. My python gui starts taking samples, and I can see the data coming in on my python notebook, so I know my hardware is working. When I hit stop, it says "Sampling Rate: xxx hz :: Done!" It never tells me it's saving to file, and I don't see any data in the CSV file. Any tips?

Hello I have been trying to test linear position with Adafruit BNO085 by following your video. I managed to get the value print out as the way as you demonstrated in the video with the BNO055 and change a bit of the Matlab code so that the accelerometer unit is g. However when I run the Matlab code, the animation is not even close to the actual movement at all. May I ask what changes have you made to the original Matlab code such that u can produce the clip at the end of the video? Thank you very much.

BNO 사용할 때 이게 움직이다가도 가만히 두면은 원점으로 converge 하지 않던가요? 저는 bno-055사용할 때 그렇더라구요...

Hello, Thank you for your video. I have a question about the data recorded by the sensor. In my case I used a sensor WitMotion Bluetooth BLE 5.0 9 Axis WT901BL, it sends the data directly to a software developed by the same company WitMotion, we can extract the data in text form and then convert them to CSV. I collected the data of the accelerometer and the gyroscope as well as the magnetometer on the same CSV file, but when I transfer it on Matlab it does not work, error in the file. I don't know if the problem is in the structuring of the data file or if it is necessary to change a detail in the code? In what form should the data be saved for the code to work? Thank you

Thank you. What is the repeatability accuracy. i.e. for example, you keep it at ground, move one feet up. get back to ground, will it show same in calculated value? Is it possible to get small sudden movement say 0.1 mm using these sensors?

Thank you for the video. Helped me a lot. I was wondering if there's a way to see this in real time instead of storing it in a csv file.

Hello! I am trying to adapt this code in real time with another type of sensors (Xsens MTw Awinda) but I don't know what do I have to put in SamplePlotFreq. Can you help me with this please?

Cool Bro..

first, thank you so much for opening your amazing project. I have some question, is those python code working with Real time or only by demo? I connected with my BNO055 sensor and ESP32, but 3D animation is automatically moving by itself. thank you! 좋은프로젝트 감사합니다

So, do you think that BNO055 is much way better than MPU6050 to estimate the linear position? Because, I'm trying so hard to estimate the linear position using MPU6050

his sir,, I had a question ,, I am currently working on a project to find the final position using imu sensor data,, can you help me with that??

Was the Mahony filter built based on the Kalman filter? Does it make use of statistics as well and add a high pass filter along with it?

Hello, Please, are the data (Data time, Data Rotation matrix, and Data EulerAngles) necessary for the calculation and display of the positioning, because you are not using it. Also, for the packet number you have put an increasing number from 1 to 10000, but the packet number in the original example is different. Does this affect the calculation? One last question, is Data Rotation matrix recorded by the sensor? Thanks

Is there any way to convert this code using a leonardo arduino instead of an ESP32? If so, you could try to explain it to me, I started an indoor tracking project with a 6050 MPU, but I only have one leonardo arduino, and your video was one of the best I've found on this subject, but as I'm very new to this subject, I don't know if it is possible to perform this "conversion". Sorry for my English.

Two Thumbs Up!!

Hello~^^ Is there a way to calculate the direction the gyro sensor moved in cm or mm of x-coordinate y-coordinate z-coordinate?

Hello, what is the accuracy of the position data in mm in xyz movements? Have you been able to test it with the help of a ruler or meter? Thanks.🤙

Few weeks I've tried, i can save the Datalogged by using your python code. Actually when i start the simulation, the result of animation is kind a different with actuall motion. How do i solve this

Hello, can i use this as a precision gps sensor for an ardurover or is there some factor that would not allow this implementation?

Hi! I'm trying to get your code working on Windows, but I'm having trouble with python part where you made "simple serial application", I've managed to start it, but it doesn't want to create samples to csv. file. I have mpu6050 sensor and esp32, but I didn't use TFT screen, so I deleted everything in your Arduino code that has TFT written in it. I also see that I have a bit different pinout on my esp32 than yours, I hope that isn't problem? Thank you for your answer.

Great video! What can I use instead of TTGO that can guarantee similar results?

Hi! Thank you for your video. Is it possible to use this code with an Arduino Nano 33 IoT with an IMU LSM6DS3 integrated? it seems a convenient board for wearable devices.

Could this be used to track a 3D handheld scanner of would it drift?

I have data accelerometer (ax,ay,az) in excel file and I want to have a 3 axis position trajectory using Kalman Filter in Matlab. Can you guide me in this regard.

great video ..Im wondering what are the changes in Matlab code if we work with Arduino Thank you

How can i solve no module error when I run the python code in pycharm "import serial.tools.list_ports ModuleNotFoundError: No module named 'serial.tools' " can you say solution for this

Hello Sir. Thank you for the video. I am working on a project to identificaty location points within 100 meter range. Is it possible to contact you to get some advice?

Are you aware of any real time libraries for use with the BNO055 vs. Going with recorded data and Matlab post-processing?

failed, cant use esp32 and bno055 with your code. would you explain how you collect data? I just need to fix a data form issue. I can use arduinospreadsheet.

Could you 3d plot this all on arduino with a screen or does it have to use matlabs?

Hi I’m wondering if I could use this program with a BNO085 and a qtpy esp32 s2 to wirelessly transmit the data, could you help me out please ?

Will it work if i were to track a circle with a diameter of around 50m ? And will the precision be to the point? 🤔🤔

Hi, this is a very useful video! But I'm wondering what the raw data look like. My output IMU data now contains a(X, Y, Z), g(X, Y, Z), and m(X, Y, Z). I don't know if it's the right one to run the code. Thank you!

Does it works for an flutter app, that could be on real time, but like just making a higher sample time?

Are you using Kalman Filter?

Nice video, but can the position display be shown directly on the arduino serial monitor without entering matlab?

I mean how to show the top view, left and top view ??. In my own, the steps of previous position don't showed. Only 1 dot (actual position)

Hello,can you show me the circuit diagram to see how the components are connected together?

Hi... I'm interested in this project and I have a question. Why it is linear only ?. Can't we track at least 2 dimensions like x and y ?

Hi @That Project . How can i convert this code to adapt it to arduino one?

Hi. Very helpful video, thank you ! You are maybe THE solution to my problem acquiering accurate position from IMU. The code you used in matlab comes from 'Oscillatory-Motion-Tracking-With-x-IMU'. I saw x-IMU is a quite expensive IMU and I was wondering how you used their script to get real time data from another IMU ( MPU6050, GY-BNO055 ). Are functions like 'xIMUdata.CalInertialAndMagneticData' understandable for another IMU ? The problem is that I do not really understand the link between the Matlab code and the two IMU you used. Is it compatible ? Also, given the end of the video, would you advise rather GY-BNO055 than MPU6050 ? I hope I'll get an answer :) Thank you in advance.

How did you add the multiple views?

Hello, is the data being output dynamically? if so, how?

Nice video. I need some help with my project.

very good i need help

Why not use the two chips in one circuit? They are i2c and they have different addresses.

Hi, I am getting garbage data values after say 30 percent of data acquisition when asking for 7000 data sets. How to resolve this

Hi eric, i'm ur new subcriber. Thanks a lot for this, may i ask? Can u send me your csv from ur own recorded trajectory?

Hi. I can use mpu9250 for project ?

Thanks, Is this code works on arduino Nano ?

Hi how to run file csv realtime.pleases

hi.. can we do it in realtime ?

Can we have the code as an .ino file please

No velocity drifting?

bno055 can track in realtime .

Pls share the matlab project, or i could buy it

Send phone imu data through wifi to pc then to 3d objects i will be unique

der

it would be great if I didn't have to pay just to import the project into MATLABS
