- Drones have evolved over the years and become perfect flying machines. Why are drones designed the way they are today? Why are they so efficient at moving so swiftly? In this video, we’ll learn about the drone’s mechanical design aspects, along with its electronics controller, sensors, intelligent algorithms, and even satellite technology. So, let’s start a design journey starting with a permitted drone and moving on to the most modern drone.

If I saw this video 1year ago, my life would have been so much easier. For my bachelors degree final year project, I had to learn these scenarios to get the knowledge for weeks. This 10 minutes is way more valuable than hundreds of rubbish research papers.
Damn…F
I want to talk to you bhaiya.... please give me your email or whatsapp...
Well those research papers ain't actually rubbish, but yeah, this video would have been a cherry on top
Yes but what you have to remember is that this video was made using those research papers.

Can we get a video explaining how does an electronic Gyroscope, Barometer work? As you explained the Accelerometer...
how about how they make sensors work that possess sense ability of environment, from the scrap resource of earth
Thank you so much
@@rajendrakandel4458 welcome
Yes i also wanna know something about it :)
Me like drones
This is absolutely awesome. Kudos to the Lesics team for putting this together.
This is probably the greatest and my most favorite channel on RUclips. Please never stop making these videos. As soon as a get my degree ill become a top tier donor in any way possible.
Really, the amount of knowledge I've acquired through this channel is unbelievable. Thank you so much!
Greatest time to be alive
I've accidentally flown my Mavic 2 into different things several times now. Two times trees, one time a building, and one time myself... Each time it managed to surprise me by somehow auto-stabilising instead of falling out of the air, all while sustaining only unexpectedly minor damage. There's even a video by Destin of Smarter Every Day in which he flew his Mavic Air 2 into a pole, causing a front arm to fold in halfway, and yet it still managed to stay in the air. As a software engineer I was quite amazed when I watched Destin flick the folded front arm back to its extended position while the drone was still in flight. It's very reassuring, seeing that my drone (or at least, a drone with similar capabilities to mine) is able to handle much rougher treatment without any problems.
@Javier Solis Well, seems like RUclips didn't like me posting links. It's Smarter Every Day 245.
Also on second look it seems like it's the Mini 2 not the Mavic Air 2. Doesn't change anything about it though.
As long as you can code, things are taken care of. This is the most basic thing we can expect in engineering these days that any bad incident will be taken care of by the algorithm. Just like the airbags that get deployed on an event of a car crash. It depends on the speed of the processor and signal. And thankfully devices today are really fast to detect split second collisions.
I same with me but with no pole hitting and mavic mini
@@scheimong Thanks for sharing that info.
@@edwardspencer9397 except when airbags were introduced they weretriggered by force from the impact and then a chemical reaction. There was no electronics involved. The process was entirely mechanical.
That’s so thoroughly!!!
I just bought a KF102 drone and it is so enjoyable to control.
So impressive that those 4 fans can lift the drone easily, the air they produce for lifting up the drone is really strong
Makes you appreciate the technology in our drones even more. Cant believe all that tech inside my dji mini se
This is one of the Best explained videos I've ever watched. Thanks a ton Lesics.
● Unexpected or Deep explanation with
3D animation. Love it! ❤️
● Really helpful for understanding much
about drones. 😊👩🎓
● Nice combination of Pretty Voice and
Animation. 👌
● Excellent! 🙌🙌
@David OgundepoAs I know, it should be 3Ds Max or Maya
Thank you.
This is one of the best explanation clips I have seen in my life
Great piece of work.👍
A perfect infusion of animation and information.❤️
This was incredibly interesting. I’m a retired electrical engineer and like to keep up. Fascinating. Thanks.
I've got a 4 bladed drone that can run without a controller. Once in the air it's programmed to follow you via a tracker beacon and the on board sensors or an automatic computer program. Although it comes with one anyway so you can do tricks and more complex moves, but other than that it's fully automatic and requires no assistance. I use it for film and checking stuff on my farm.
yes drones can run autonomously as well, if you code them.
Can you share what changes you made for that?
@@sahilmohite701
Most of it was stock as it was intended to help farmers check their crops without leaving their house. It pretty simple all you need for a follow me drone is:
1x tracking sensors and receiver to follow
1× obstacle avoidance system which requires a sonic sensor, beacons and gps mapping so it remembers what path you took and will follow it again.
1× self stability sensors for more stable shots.
You'll also need knowledge in coding to tell the part how to communicate and what actions to do.
Or if you don't want to go through the hassle and have a bit of dough to spare, you can buy drones that comes with all this fresh from the box. I hope this help you with your next project, good luck👍.
I work for a company that has spent the last 5 years developing fully autonomous single rotor helicopter uavs for low level geophysical survey, we only use RC control for takeoff and landing, after takeoff all control is handed over to the autopilot and the 2.4GHz RC is switched off, UAV telemetry is monitored through a 400MHz long range data link which is also used to command the UAV to return home, we can also make it hold while we upload a new or adjusted mission and even fly it in manual RC mode using the telemetry data on the ground control station screen, although this would only be done in an emergency situation. Our UAVs fly low level terrain following beyond visual line of sight for up to 2hrs sometimes around 10 miles from base.
We also have a fixed wing vtol uav for photogrammetry that is 100% autonomous, it takes off flys a mission then returns home and lands by itself, it sits standing vertically on its tail on the ground and takes off like a twin rotor multicopter then pitches forwards and transitions into a twin prop fixed wing to fly the mission, when it comes home it circle's above home and pitches nose up until it stalls and transitions back into a multicopter then descends and lands on its tail.

I've heard of those self driving drones, alot of farms around here have upgraded to this system for crop dusting, bird scaring, monitoring and more, it's even used by our fire crew to check for bush fires in the mountains. My design was based on a very basic version of this for the gps tracking. That's so cool to hear someone else who has experience in building drones.
A kind suggestion,please do enable captions for better understanding of the terminology that has been used in the video
thank you
The tricopter design shown in this video is from the Latvian company Atlas Dynamics, and it's an industrial/military drone. It's notorious for a long flight time endurance. It's not offered in blue color, though...
This is great info for getting into FPV drones. I hope to build one soon. Thanks!
VALUABLE TIME SPENDING TO KNOW THE DRONE
Excellent explanation!
Indeed!!! 🙌💯
Drons are the most amazing invention to push up more our technological advancement of this era. May be it is the great invention for right now because it can be use in any field and become versatile day by day.
To think someone is smart enough to make computer parts like this😱🤯
It's not someone. It's a collaboration between millions of people who worked together somehow through the ages to reach this point. Even Pythagoras and others have worked on this if you think about it...
@LABscience This literally inspires me to contribute something to earth before i die. Such brilliant minds!
@@labscience8271 First of all, thanks to Nikolai Tesla ... Now you have Tesla cars that can press the accelerator pedal to work. Soon drones will be in the sky to see your city
@David Ogundepo Late reply, but thank you, sir!
@@vivekjaiswar6825 I always think about that too. I don't want to leave earth before I develop something for humanity.
Glad that inspired you. If the world thought the same way, it would be positively much different...
No doubts, this video is very informative! Thanks alot!
Also it will be great to discuss about the air density and altitude density as well as the temperature and how they affect an aircraft's flight.
The Most Knowledgeable Video! Thank You For Your Effort And Hard Work
Kalman filter isn’t a control algorithm. It’s just a state observer. 🤔
This channel is a gem. Thank you!
What a nice explanation. I have really enjoyed the video. I'll be following this channel for more, since I believe that this is exactly what you offer
These videos are very well done. great and accurate visualizations
They're back with amazing content💯💯🔥
7:52 Correction: Kalman filter is NOT a controller. It aids in sensor fusion to ONLY estimate the state of the aircraft (Orientation, height, and position). This is necessary for the controller to work (Provides feedback) but it is not the controller itself. "PID controller" is the right term. It is what actually "controls" the drone to maintain it in a desired state (Balanced hover, tilt to a desired angle, maintain certain speed etc.).
@Abhishek Reddy : Drone related information (source) ekkada available lo udho chepthava?
highly underrated channel. This is engineer's paradise.
This is such a great explanation! Thank you so much
This is video should be there in the curriculum of engineering students, golden information.
This is the amazing video that explaining very clear. It's more worth watching this 10 minutes than listening my prof 2 hrs.
Wow , amazing video as its crisp clear with the principle of how a drone works, thks
A detailed and excellent explaination of the DRONE
Well Presented & Explained , Thank You
Perfect explanation with animations.thank you very much for your information.
Concise and beautiful explanation
You just saved me 3 month all the book and school would take me at least 3 month if not more so thanks dude
Thank you for your sharing. animations are very well done, understandable and impressive. I would like to thank everyone who contributed.
If you really want to understand how the flight controller makes its decisions about where to go, I believe this is almost always accomplished via lagrangian mechanics.
there are opensource autopilots like ardupilot or pixhawk.
Very comprehensive breakdown 😀👍
thank you for making this video, i was really curious how a drone can yaw and couldn't figure out how it spins, now i know😃
THANK YOU SO MUCH FOR EXPLAINING
Awesome bro.. Really great animations and knowledge.. Loved it 😍😍❤️
Excellent video! Similarly make video about self balancing two-wheel robots like the ascento 2.
Super informative with detail knowledge , priceless 👍🏻
This is just brilliant
Excellent explanation.to.bringnunderstanding of Arial dynamic s that can be applied to design models to add additional sensor application band how weight may effect lift.wonderful indeed from a engineering perspective. Which I enjoyed learning.
Perfectly Explained!!! Keep it up Team :)
This is the best video… So simple explanation…
finally got video similar to past videos which we prefer
WOW!Great Information about the Drone.
One correction, barely any drone uses Li Ion batteries, they use Lipo these days for higher discharge capacity.
Higher discharge or lower discharge?
@@sparkly3989 Higher discharge rate i mean, ofcourse li-ion can be discharged to lower voltages than lipo but the discharge rate is substantially lower.
Still don't know why they don't use LiFePO4 which is much higher discharge rate, higher capacitance density, higher operating temp range than LiPo. I guess the reason is cost for this battery and to make new circuitry for charging, discharging
@@thexht7927 Nano carbon batteries also can be used tho
or even LiFe.
Excellent video, Bldc motor in drones is a game changer in drine technology.
This was so cool! Thank you
Amazing times were living in!
Very great content I thank the people who made this video very much. Great work.
Thank you! Very Informative! 👍❤🇵🇬
It's showing only one like button ,but I loved this a lot🤗😊
I love this channel because I learn a lot from this channel 😎
Thank you, it is very informative.
Kalmam filter is used to sensor fusion not to control the system. In order to control the stability you can use classic PID controllers, Space state controllers or lyapunov.
Wow ! Merci, Thanks
Excellent
Just outstanding 👌
How easy you make us understand!
Thanks a lot 😊
Thank you so much to create this wonderful video
i really love your videos they are so easy to understand and contain thr necessary details helpful for our knowledge keep on working❤
I love science and i love how to make use of it for a comfortable living..
Tanks a lot , brilliant work
Really interesting topic. Thanks

Love this Csi!
Great details and simplified explanation. Thanks for the work that went into consolidating and presenting so much information in a quick, easy format.
With Tricopters you add a tilt mechanism to the rear motor. They actually have some advantages over quadcopters.
One of them is low battery power consumption but quad copters have higher stability and can carry more weight
