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.
Thanks for this comparison and analysis
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.
Thank you so much for this explanatory video.
Love your Work
Cool Bro..

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.
I haven't touched the basic Matlab code. Only the part of the view has been modified to show the screen of multiple axes.
The sensor I used is a clone version of the BNO055. Something might be different from yours.
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.
Unfortunately, I was not able to find a good solution for real-time.
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?
This may be more helpful than my explanation.

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??
Did you get it?
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?
Due to the drafting of each axis, this is not quite as accurate as you might think. You can get an approximate position, but it won't be in a perfect position even if you put it back in its original position after a move.
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
According to the test result, seems like BNO055 is much better than MPU6050 but it's hard to say that. When I collect the data from both devices, try to do the same way as much as possible. However, there may have been a better method depending on the device's characteristics. Please check each datasheet and find the best sensor for your project.
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?
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
If you create the same csv in this format, no problem.

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
My Python code is just for sampling data. Everything has to change in order to be calculated in real-time.

Hello~^^
Is there a way to calculate the direction the gyro sensor moved in cm or mm of x-coordinate y-coordinate z-coordinate?
Unfortunately, I don't have a solution for that.
Great video! What can I use instead of TTGO that can guarantee similar results?
The point of this project is the IMU sensor. Of course, you can use any ESP32 MCU.
@@ThatProject one last thing please..if I want to summarize the steps to follow from the beginning :
-collecting data from IMU than applying the matlab code to see the signals(velocity,filtered signal..)
- obtaining csv file contenting positions
-hardware
-linear position
Is that right or im missing something ?
Thank you in advance
@@wahbimanchoul2666 I think you're on the right track. Any updates?
What kind of IMU sensor are you using for your experiments?
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
The data obtained from the sensor is the gyroscope and the accelerometer matrix. Based on this, all calculations are made in Matlab to obtain positioning. The packet number doesn't really matter.
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.
Unfortunately, I haven't do any projects with the Leonardo Arduino. So I have no idea about this board. Sorry for not being of any help.
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?
There seems to be a problem when writing the last CSV part. How about debugging this part?
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.🤙
Good point. I can't answer because I haven't tested it accurately. I think that perhaps the accuracy can be improved by scaling up and down in the space with coordinates.
Are you using Kalman Filter?
It's using High-pass filter. Check the matlab code.
Hello, can i use this as a precision gps sensor for an ardurover or is there some factor that would not allow this implementation?
Well, what I did here is more of a test for an IMU sensor. What's your plan to use IMU sensors to increase GPS precision?
@@ThatProject my plan is to use the coordinates generated by the IMU and transform the x axis into latitude and y into longitude and send this to arduover as if it were the response from the gps module itself.
Are you aware of any real time libraries for use with the BNO055 vs. Going with recorded data and Matlab post-processing?
I don't think so. There are no such libraries so you have to implement your own. Tried several times but couldn't get the right result.
great video ..Im wondering what are the changes in Matlab code if we work with Arduino
Thank you
I tried once to make it calculate in real-time but that was not easy. If it works, I'll share it through my channel.

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 ?
There is a difference between sending data in real time and storing the data internally before sending it. Have you considered this?
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.
First, please check whether ESP32 outputs the value of the gyro sensor and the accelerometer sensor properly from the console.
@@ThatProject Jep, it works now, can you display data in real-time? Readings from gyro and send it to matlab? I can now save samplings in to csv. and look readings in mat lab, don't know if it is possible in real time?
@@ivansucec2510 I don't have a plan to work yet, but I'll let you know when it's completed.

Could you 3d plot this all on arduino with a screen or does it have to use matlabs?
It has to use Matlab.
@@ThatProject ah ok thanks. It was only because I want to try this idea but plot something like temperature in different positions in a room on a hand held device.
Does it works for an flutter app, that could be on real time, but like just making a higher sample time?
This is not a flutter app, it doesn't work in real time.
Nice video, but can the position display be shown directly on the arduino serial monitor without entering matlab?
The reason Matlab is used here is to calculate the position using data obtained from the IMU. Without it, this is nothing.
@@ThatProject Do you know of a sensor that can get a position like your video, but doesn't use matlab?
@@barajr1349 For this project, an IMU sensor is needed, and the data obtained from it needs to be processed. There is no sensor yet that accurately calculates x,y,z coordinates in 3D space.
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
That's the same as mine. Accurate positioning is not possible because the values coming in at the beginning have not been fully calculated.
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
If you're using PyCharm, then it shows you to install the requirements.txt. Or you can install the package pyserial by youself.

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

This is done by first collecting sampled data and then reading and analyzing the data in Matlab. For actual use, many things must be added and implemented.
@@ThatProject Hmm, I see. That helps a lot. I'll be trying my beat to make it run in real time.

@@ThatProject ok noted, thanks for advice so far
Hello, is the data being output dynamically? if so, how?
After collecting sensing data first, visualization is performed with the data.
@@ThatProject may i ask what visualization tool did you use?
@@junzhezhang5397 As you can see in my video, I used Matlab.
Why not use the two chips in one circuit? They are i2c and they have different addresses.
I know that but to get a precise sampling rate from each sensor, I configured it this way.
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 ?
Linear for the X, Y, and Z axes.
@@ThatProject Oh, okay. I thought the unit could only detect one axis because you were moving it up and down.
I've seen your other videos on tracking using UWB, which has good accuracy but requires external anchors.
Is there a way to increase the accuracy of IMU-based tracking without using external hardware? Would it be possible to use techniques like SLAM or odometry in combination with this project to improve tracking accuracy and reduce drift?
@@akshayjose6555 It's possible, but it takes a lot of effort. In particular, it is possible to determine a specific location based on UWB, but it seems that a lot of work must be done to integrate an IMU sensor and operate like a SLAM without image processing.
@@ThatProject Is it possible to add image processing in it ? (I mean the IMU based tracker shown in this video)
I've seen some open-source projects that use a Raspberry Pi and a single camera to achieve this, and I've even seen someone do it with just an ESP32.
I’m including a few interesting open-source projects below

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.
To use the Matlab script they provided, we first had to collect data such as Accelerometer and Gyroscope. After that, I was able to save it as a CSV file type and read it in Matlab to obtain the coordinates where I moved while holding the sensor.
I don't understand the "compatibility" you mentioned. The Matlab script and data collection process operate independently of each other and require completely different workflows to perform them simultaneously.
In my tests, I think the BNO055 showed better results than MPU6050.
@@ThatProject Ok thanks for your help. I misunderstood some things. I thought what you presented was real time processing. So the xIMU script in Matlab is not acquiering any data in real time. It only reads raw data from the CSV file (accelerations, angular velocities, magnetic field from the IMU) and treat it to get position.
By the way I think you did some calibration to the sensor before having accurate results, didn't you ? Or did filters handle things anyway ?
@@SpaceDragonYT If you look at my code, in the case of BNO055, it starts after performing its own calibration function before starting sampling.
@@ThatProject Ok I see. Thanks a lot for your help. I'll try this, I hope it will work :)
