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 TH-cam 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.
@@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
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.
@@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.
@@ats-3693 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.
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.
● Unexpected or Deep explanation with 3D animation. Love it! ❤️ ● Really helpful for understanding much about drones. 😊👩🎓 ● Nice combination of Pretty Voice and Animation. 👌 ● Excellent! 🙌🙌
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...
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.).
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.
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...
@@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
@@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...
@@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
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.
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.
@@NerdKing9826 Being an engineer you should always try to design a single equipment for multi purpose.. and are you serious that it can't be used in woods? That's basically used whenever you aren't sure about the quantity of obstacles and the area.... That's the kind of place it was basically built for....
@@ajithbharadwaj3344 I think a drone using visual slam could probably make it's way out of woods if it's near the edge, but Visual Slam is not good for determining position in homogeneous environments (deep in woods). Im not talking about collision avoidance btw (it'd be way easier to use sensors other than cameras for that), I'm talking about true navigation and positioning. Visual Slam can definitely give great positioning accuracy when there's enough heterogenous features in the environment though
@@NerdKing9826 yup, that's correct. Without differentiating between features of environment at different positions, drone can't localise itself using Visual Odometry.
The Neonode Air Bar is a touchless sensor bar that uses infrared (IR) light to detect hand gestures, allowing users to control devices without physical contact. Here's a simplified explanation of how it works: 1. *IR Emission*: The Air Bar contains IR LEDs or lasers that emit infrared light patterns onto the detection area. 2. *Reflection*: When a hand or object enters the detection area, it reflects the IR light back to the Air Bar. 3. *Detection*: Photodiodes or sensors in the Air Bar detect the reflected IR light and send signals to the microcontroller. 4. *Gesture Recognition*: The microcontroller processes the signals to determine the hand's position, movement, and gesture (e.g., swipe, tap, or hover). 5. *Output*: The Air Bar sends the recognized gesture data to the connected device (e.g., computer, TV, or smartphone) via wireless or wired communication. 6. *Device Response*: The connected device receives the gesture data and responds accordingly, performing the desired action (e.g., scrolling, clicking, or navigating). The Neonode Air Bar uses proprietary algorithms and advanced signal processing to achieve high accuracy and reliability in gesture recognition. Its touchless technology enables intuitive and hygienic control of devices in various applications, including smart homes, gaming, and public installations.

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
