In this video, you will learn how you can measure the vertical velocity of your quadcopter drone using the MPU6050 accelerometer sensor.
The purpose of this video series is to learn the basics behind a quadcopter drone and enable you to build one yourself, by dividing this challenging project in several easy-to-understand parts. You use the capable Teensy 4.0 microcontroller together with the easy-to-use Arduino language. - วิทยาศาสตร์และเทคโนโลยี
I wanted to know how you are measuring yaw values. I couldn't find it in your videos related to gyroscope and accelerometer. Could you tell me in which video you have discussed about yaw measurement?
Hello, I really enjoyed your videos for making drone from scratch. I am planning to make one with the help of your videos and codes. I was wondering if you could also show how to connect a camera to the drone and how to include that in the code as well. that would be helpful. Thanks
Gracias por compartir.
Hello, I implement the related formula but my results are showing acceleration in Z direction when quad is tilted. Tilt compensation is not working, do you know why? It works between -5,5 roll & pitch, but when tilt angle exceeds 5 degrees it becomes meaningless.
Thanks for this video but pleaes can you explain in 2:52 how the Accz,i was calculated after adding the three equations to together without dividing the result on 3
because it will be like this
3*Acczi =
I saw this vid pop up on my recomended list and did some checks on google, is this to estimate how much the quadcopter decreases in altitude in horizontal flight?
your videos are super helpful but the same equations can also be derived using DCM
Please someone can provide information or a link how to find X and Y axises linear velocities, I don't want angular velocity (I am getting it) but for my project I need to find travelled position of the robot
Could this also be used to measure horizontal velocity and cancel out any drift in self leveling mode?
Im guessing to do so. The accelerometer would have to be virtually leveled, even in forward flight
Para la velocidad horizontal necesitarías el ángulo absoluto de el eje Z / Yaw pero sólo tiene Roll y Pitch
Also are planning on using Quaternions instead of Euler angles in the future?
Not immediately, it would be mathematically more elegant but way harder to explain ;)
How to use mpu6050 to calculate speed ?
i can't find the full code on github please someone help
Really great work , but can i also measure the linear velocity in x or y directions with the same method ??
yes, use an accelerometer
hi sir the part 18 seems to be missing from the github page
hi bro. may i have the method to caculate horizonal velocity for X and Y axis
I am trying to find out a way to do so ?
If you're using an altimeter/barometer couldnt you also integrate that into vertical velocity measurements?
just remember that barometric pressure changes from place to place and throughout the day. You'll need a way to correct for changes in Barometric pressure.
Yes that will be the topic of the next video, we will use a Kalman filter once again
or... maybe you can just directly integrate the acceleration measured from Z-axis with the elapsed time
I guess that approach will make you drift because of the integral, I was thinking of also using a high pass filter but I've never done it. Please share some insight if you tried
We need to subtract 1g from the vertical acceleration you measure from the accelerometer.1g does not produce any "visible" velocity and the accelerometer can't distinguish between gravity and other accelerations. Or else your vertical velocity will constantly decrease like in your video.
how? Can you explain me further more?Please.
