No music in the background. Perfect video! Thank you!
I came to know about the existence of quadcopter during my school days from the movie "3 idiots" and today I learnt the principle behind this. Thankyou for making this video.
Kindly make a video on solar powered drones.
Haha hhaaaa
Are u in FIITJEE ritu raj??
South Delhi??
As a drone operator I can say that you have to add yaw to fly a circle or to make simple turn etc..
Besides when the drone is hovering, the motors are not necessarily rotating at the exact same speed (due weight distribution, wind) the gyro's inside fight controller of the drone regulates the motor speed of each motor in order to stay level. For example, if you add more weight on one motor arm, that arm will spin faster to stay horizontal.
As a pilot, I approve this comment! 👍
The most important part of a drone is its sensors and electronics package. If this is good enough you can use all kinds of motors and inefficient blades to produce results as far as power exceeds weight.
Dany Varna Each part is important. In many cases lift can exceed weight but the craft might still be impossible to tune / fly correctly cause mechanical factors like stiffness, center of gravity position and many others.
@@carboncopters5674 , turn your brain on. All of what you mentioned is either performance related or correctable to a satisfactory level by the electronic suite. Every part od important bit some are decisive, thus you start with them as a choke point.
Dany Varna No its not. Electronics cannot change the laws of physics. Its entirely possible to make UAV impossible to fly in a controlable manner not to mention ,,satifactionary” level if for example the center of gravity is too far away or some elemnts of the craft interfere with air stream. You obviously have no experience in building crafts of this type or especially the experimental ones if you deny the obvious significance of mechanical contruction.
@@carboncopters5674 , you seem to know little. Let me help you. Do you understand that most current military flying machines that we use are either not aerodynamic or have been planned with a level of aerodynamic instability? :-) Read, man. I am building drones so I know what I am taking about. With enough power and a good electronics-sensors module you can make a brik fly. Chech the development of quadcopters and compare it with the timeframe of the rise of cheep electronics.
Dany Varna Aeroplanes are built instable statically on purpose and it is a well planned and calculated process. Its not ,,do whatever and it will fly”. This actually the proof of significance of the airframe design itself and using the advantage which electronics gives. The fact that you ,,build drones” doesn't make you be anyone who can ,,explain things” especially to people who design stuff you probably buy and stick together according to manual and tutorials. If you want to prove your point about electronics does it all, please show me bi-copter or tri-copter that flies in a satisfaction ally way withtout flaws of these configuration, of course self designed frame. You are ,,pro''' after all.
I loved it ,people like you can change the world
the voice was perfect. Thank you for the information!
I love all makers of this channel may you live 1000000 years😍😍💪
Why only we guyz are soo fast to watch this video. Even though we aren't engineers
Best video #Big_fan
Engineering isn't a degree , it's a mindset
Wow this actually made sense
Thank youuu
Really appreciate it
You guys are freaking awesome!
waited for this for a long time,just what i wanted
The drone will not turn in a circle if you just pitch and roll it. it will move diagonally. you will need to induce some yaw in order to constantly adjust the drone's heading.
Definitely! 👍
You are correct!
Yep,
-dji mini 2 owner
If you do the roll and pitch at the same time, you're right. But if you do the pitch firstly and if you do the roll after the drone gains a certain amount of velocity,it will do a circular motion
of course
It is a GREAT and very benefitful and enjoying video!! thank you very much!!
Ya know, I actually understood what the heck you were saying! That's not an easy accomplishment for you to do! Thank you, great explanations!
Thanks a lot for this great video.
Thanks for Explaining Lift Force Very Easily.
Wow...amazing....animation as well as explanation.......
"one more vid before bed"
me at 3:00 am:
Wonderful video. Thanks!!
Really nice visualiser and explanation. Got a question - why not add four blades to each propeller instead of two, wouldn't it use less energy to get the same amount of lift force?
No due to the increase in drag
Thanks for all the great information… If you have time could you explain how, given the physics of the airfoil, an airplane can fly upside down? Logic would dictate the inverted “lift” would pull the plane to the ground...
Please make a video about thermoelectric effect
Thanks for the good explanation
yes well understood
Loved the question at the end... it turned the video even more interesting.
I hope we get a video about hydrogen fuel cell powered cars and perhaps something about car drag for high speed racing
Check out the videos that Real Engineering made about this subject, they're awesome.
@@nicodiveira my G thanks
Car drag is the application of Stokes theorem when the car reaches its terminal velocity it can no longer accelerate forward but attains a max constant acceleration which just ewuals the opposing drag viscous force.
@@nicodiveira aaàaa

this channel desarves more.... explation and editing is super top knotch. i hope he is making more money.
About spinning in a circle is true as long as it is in a closed space or at least the intensity and direction of the wind does not change.
If you pitch and roll, wouldn't you just go in a diagonal direction. So not going in a circle but still in a straight line. To go in a circle you'd have to yaw as well and it gets quite complicated at that point.
Well the logic that I could think is since circular motion is a 2d motion and requires force in 2 directions only thus only pitch and roll is required. If we apply yaw also then it will be a spherical motion instead of a circular one. I may be wrong but this is only possible explanation I can think of.
There's a coupling between roll and yaw. Typically, it's way more efficient to roll to change direction than yaw.
You are correct. It is equivalent to "strafing" in video games. Both pitching and rolling preserves the direction that the quadcopter is facing.
this
yea, but you would go in a circle, but the front will not we straight as shown. You would need yaw and roll to do a circle like is shown
Great explanation thanks .
wow i learnt how to make a model of drone on coursera now learnt its mechanics amazing video @leaarnengineering.
Can you give a name of course
@@skySanter its a course on digital manufacturing by autodesk
@learnengineering
Good class sir about the drones thank you very much you are lifting the knowledge of students which we can't learn in our colleges I will support you sir
he must have used a lot of lift force ;)
1 yr ago. i was searching about this topic and now YT recommended me the video i was curious about
Amazing Engineering.
You guys are the best.
Muahhhh...!! To this channel n hats off to the animations n well of course to the speaker...
Just brought the mavic mini 2, it helped me to understand it's science behind it, now I can easily fly it 🙌
Same for me!
Mini 2 is a pretty nice drone!
finally I got what I was searching for a long time.Thanks a lot for the clear explanation.
Wow!!!very interesting and informative.
The simplicity of drones with motors that can change rpm sharply than combustion engines
also mass gyro disc stabilized drones, and planes, even with one miss aligned rotor
Great visual... my only comment (correction?) would be that yes, different motor speeds (torque) on the diagonal motors causes yaw. To pitch or roll you are increasing the motor speed in either the front/rear or right/left motors to provide more or less lift to make it change it's attitude, not torque. Please correct me if I am wrong?
One thing you should ask yourself is what is torque? A force that causes rotation. when you change the motor speed,the blades creates more lift which provides torque to that side of the drone.
if you know how a drone flies and master it, you already have short hand experience of controlling a copter. Helicopters use some common concepts that apply on a drone as well.
Before I came to watch this video I had already put this in my mind but one thing I did not think about it was the way the engines turn (N + S + N + S).I thought the only helicopter effect engine could do that
¡Gracias!
Over powered 👍
Nice explanation !
Thanks for your information
You said it nicely bro.. thank uu..
Nice job!!
Beutiful explanation , make a playlist for each topics.
Very well explained. Knowledge shared to the mass. Thanks!
@4:52 that can only stay hovering like that if all 4 propellers are angled parallel to the ground and are rotating at the same speed, given that the lift is equal to the total weight of the drone.
And also if there's no wind movement
Nice video, i like it!
Really very nice sir, i know that you have done very hard work to make this video. So I gave like to your video.🙂😉
Very good and helpful for science students🔔
I love your videos
Mind blowing
Thankyou so much
This video is very good for the beginners
Drone flight ✈️ dynamics explained very easily using animating & using drone this Awesome wonderful about drone science in today world technology we can use to spend spy of the things & place using flight ✈️ dynamics
Amazing
Nice. i am from India ❤❤❤❤❤❤❤❤
Very easy to understand its theory
Thank You! Another Great Video 😍
Its amazing
thanks a lot
Awesome, 👏👏
I like it l was here four minutes after streaming
3min 😁
Awsm!!!!
Amazing educational video 👍
Great video sirji
Very good animations
Good Info!!
I like your video's 👍👍 good information
Wow what an amazing explanation & animation... The best one I've seen so far on this channel as it's so simple to understand even to those without an engineer degree
Thank you
Great video! It would have been nice to mention the gyroscopique effect of motors and blades and how it affects the drone rotation
Hey thanks for the info at 6:04. I'm trying to code in Unity to use physics forces to rotate objects around a certain point just like what was shown. That helps me realize that the solution is much more simple than I thought. Cheers!
@Hussain Mehemud Kusum Yeah C#. I'm a Technical Artist for game development. The comment was in response to a personal project i'm working on where i'm driving the transform vector position based off of physics instead of forced script calculations .
Excellent video
Good explanation
Very nice explanation
And what control drone to moving further out of RF controller ?
just subscribed can't wait to learn more
2:45 Does it also apply in V-22's vertical take-off ?
please make the video on working of different micro sensors used in electronics.
GREAT VIDEOS
Awesome. Vivid illustration using graphics and animation. Thank you for producing the educational video.
Now, i already know!
Does it means all drones first tilt for forward motion !!
outstanding
great video. expecting to see many more videos like this on drone mechanism like the communication between the remote controller and drone, where does satellite communication plays role in this drone operation, etc etc.
Watching this for trailmakers build
Estou aqui assistindo seu vídeo e me inscrevendo no seu canal e deixando aquele like para o amigo
Great video and nice explanation. Talent in action. Congratulations for the job done.
nice explanation for dummies:)
A little correction that does not remove anything from the educational value of the video. By convention, torque is a vector that is directed upward the vertical axis for anticlockwise spin and downward for the clockwise spin. If the angular speed of the rotation of the rotors is constant then the torque is zero. I would rather talk about angular momentum since it is related both to the angular speed and the rotational inertia of the body. Edit: On second thought you are fine using just the concept of torque because in the real work the friction force of the rotating parts of the electric motors can be overcome by an opposite force that would be the torque. So even for a constant angular speed of the rotor, to overcome the friction force of the axle of the rotor and the drag force of the blades a constant positive torque is required. Peace
Excellent video sir.......
But I really don't understand how pitch+roll action can make a circular motion.....
I think the drone will have a strait motion......
Diagonal motion as the net force of side and forward........
Thx
Nice video 👍
