No music in the background. Perfect video! Thank you!
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! 👍
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??
Now I know why my drone crashed.
All Motors spinning in same direction!
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
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.
You guys are freaking awesome!
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!
It is a GREAT and very benefitful and enjoying video!! thank you very much!!
waited for this for a long time,just what i wanted
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
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
the voice was perfect. Thank you for the information!
I loved it ,people like you can change the world
I love all makers of this channel may you live 1000000 years😍😍💪
Wonderful video. Thanks!!
"one more vid before bed"
me at 3:00 am:
Wow this actually made sense
Thank youuu
Really appreciate it
Thanks a lot for this great video.
Thanks for Explaining Lift Force Very Easily.
Wow...amazing....animation as well as explanation.......
1 yr ago. i was searching about this topic and now YT recommended me the video i was curious about
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...
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

Wow!!!very interesting and informative.
2:45 Does it also apply in V-22's vertical take-off ?
And what control drone to moving further out of RF controller ?
Great drone theory of flight.
Great explanation thanks .
Great video sirji
this channel desarves more.... explation and editing is super top knotch. i hope he is making more money.
Muahhhh...!! To this channel n hats off to the animations n well of course to the speaker...
Please make a video about thermoelectric effect
Does it means all drones first tilt for forward motion !!
Nice job!!
Thanks for the good explanation
You guys are the best.
I like your video's 👍👍 good information
Very good and helpful for science students🔔
Any idea why drones never use ducted props? Would seem to me those are easy ways to gain efficiency
Amazing educational video 👍
Thanks for your information
Nice explanation !
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 ;)
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
Over powered 👍
just subscribed can't wait to learn more
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
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.
Nice video, i like it!
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.
Awsm!!!!
If we want to turn a drone we need to change the speed of the two pairs of propelers that i understood but as u sayed if speed of propelers will defer it will rotate coz of different speed of stator which are applying force in opposite direction of motor. So why is it not a case can u plz explain?
Excellent video
Awesome, 👏👏
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
You said it nicely bro.. thank uu..
Mind blowing
This video is very good for the beginners
How do you do such animation? What software do you use?
@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
which software you used make animations?
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.
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!
Really very nice sir, i know that you have done very hard work to make this video. So I gave like to your video.🙂😉
Amazing Engineering.
Good Info!!
Very nice explanation
Loved the question at the end... it turned the video even more interesting.
I love your videos
Beutiful explanation , make a playlist for each topics.
Very good animations
also mass gyro disc stabilized drones, and planes, even with one miss aligned rotor
GREAT VIDEOS
Very easy to understand its theory
Hi! Can you please explane me how crane works? Thanks for your videos.
I like it l was here four minutes after streaming
3min 😁
finally I got what I was searching for a long time.Thanks a lot for the clear explanation.
Nice. i am from India ❤❤❤❤❤❤❤❤
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
Its amazing
Good explanation
¡Gracias!
Nice video 👍
Question : when the drone is descending does the motor spin another way or slow down ?
motor spins slower, in order to reduce the net lifting force to a value lower than the weight of the craft
outstanding
Great
please make the video on working of different micro sensors used in electronics.
Thank you
How does weight machine work?
Can drone stay still in a tilted position?
Amazing
Now, i already know!
So Nice 😊😊
Thankyou so much
So I crashed my drone. Everything still works however there is one problem.
The ascend and descend speed is extremely slow. (0.6meter/second).
The propellors are a bit damaged.
Will replacing the propellors fix this problem, or do I need something else to fix this problem?
thanks a lot
@learn engineering can you make video series on how rocket engine are controlled including variable throttling, gimbaling AND how rockets are controlled roll, pitch, and yaw AND which hardwares or actuator are used for this controls AND how rockets trajectory are controlled, by which hardwares ? Please please please please please.
is the rotor speed/power of flying 20m from the ground equal with flying 5m above 15m rooftop?
Ground effect is not significant for a small drone unless you fly much closer to the ground, like a foot...
Very useful
