    Episode 2 How Drones work the IMU

    Can you tell me what is accurate Ansia? My understanding is that the gyroscopic and the magnetometer elements of the IMU controls the direction and position in the air. "A gyroscope is a device that uses Earth's gravity to help determine orientation. Its design consists of a freely-rotating...

    How drones work

    It turns out that the barometer is in fact critical for altitude and landing. In combination with the IMU. "Barometric Pressure Sensor A high-performance barometric pressure sensor built into the drone precisely measures altitude and can be used in combination with the IMU’s readings for...

    Look at the size of an IMU! That is very tinny. Sneeze and its gone IMU Inertial Measurement Unit - Xsens 3D motion tracking

    How drones work

    I just copied and pasted this from the PhantomPilots I just posted to. Sorry its so long. This is getting less complex as we go along, but it is starting to make sence. The attitude and heading reference system looks just like the inertial measurement unit (IMU). Very confusing till I read...

Even though some of these instruments are complex it's fascinating how they work." on the PhantomPilots channel. So are we agreed that the...

    How does the Tello remain so still

    Thanks guys very helpful. Great links volate!lo, I am planning to do the first video on the Visual Position System. Its called Optical Flow System and works just like an Optical Mouse works, like taking zillions of images of the ground for stabilization. Which is why drones get confused over a...

    How does the Tello remain so still

    Thanks Ansia. But it is so hard to find stuff directly on the Tello systems, infact on any drones systems. So any help would be appreciated, I'll post on other pilots sites.

    How does the Tello remain so still

    I have been trying research this question for ages the information is so difficult to find I know it uses optical flow senses and a barometer but I can't find out how this is used on the Tello. I would very much appreciate if anyone can direct me to articles that explain how the Tello could...

    One motor not working

    The thing is I can't remember where I got it from I tried the places where I think I got it from but I can't find it. It's not very much but I will claim it on the insurance. But I'll take it apart in the morning and see if I can solder it myself Thank you for the help briest.
