Great video.Can you please make a vibration sensor circuit which is very sensitive.
PIA is the honeypot of FBI
What a detailed video, I thoroughly enjoyed it.
Thank you, Sabin. Very pleased to hear you enjoyed it.
@EngineeringMindset I like it alot.
What software(s)do you use
Ok you throughly enjoyed it, did you learn and understand it?😊
I like engineering mindset, Lesics video a lot
The 9g is the actual weight of that little blue servo. 9g is a general size classification. An example of their general torque is about 2.5kg/cm. They range between 9 and like 13g of actual weight. It's considered a mini servo.
The larger servo is a standard servo, again a general classification of it's size and actually has the kg/cm rating printed on it. Standard servos are about 40g of actual weight.
exactly
Those 9g servos are the most widely used due to their compact size, light weight and relatively high torque for their size and weight. They fit easily in almost any size of RC aircraft and cars.
This.
Correct! Except it’s 2.5kg*cm.
True
Correction: 25 kg.cm at 3 cm is 8.33 kgf, not 6.25 kgf. The latter occurs at 4 cm, not 3 cm.
Yup, simple law of any lever that progresses linearly in terms of distance to force 👍
I really needed to point this out before continuing watching.
Glad to see this. I wasted an hour and a half trying to figure out what I was doing wrong in calculating the values. Thanks for the reaffirmation. I feel this comment should be posted as a sticky note at the top.
Good to know I'm not the only one
As a professional servo engineer i enjoyed the video!
To be clear robots and other precision control units do not use these types of motors or pwm signaling, but are still called "servo controlled motors". The feedback driving the control system can be quite different.
What type of motor is used in robotics
@@pujachand1053 stepper motors
@@kaizen9451 Hahaha. No. DC or AC Servo motors with absolute encoders.
Yes, I was wondering what the hell these servos were as they aren't the type that I think of when I think of servo motors. Are these bang-bang type? Most industrial applications utilize rotary encoders on the back of the motor, with a gearbox assembly added to the front.
@@kaizen9451 Lmao not even close.
I am astonished, I have never seen such a great video that teaches the working of servo motor in such a great illustrative way. I understood these concepts so easily which I wasn't able to understand before, even going through the hundreds of websites that demonstrate the working of servo.
30+ years ago vacuum was the choice driving energy to move blend, mode, recirculate doors and flow valves in automobiles. Actuators are much the choice of engineers since about the early 90s with a mix of vacuum and actuators being found in various models of vehicles within a manufacturer's lineup. Today, I can't think of a single manufacturer that employs vacuum to carry out these functions within an HVAC. Rear climate control has become so common and is much easier to accomplish using actuators ( a servo with a specific design in mind). They've even got smart enough to make the footprint quite universal within a vehicle so that one actuator design fits the door shaft of all the locations. Current monitoring transistors give these actuators the appearance to learn their range of motion when installed. Truthfully it's the control module that learns this range I am more than reasonably certain.
People love you more than you think engineeringmindset!!! I feel blessed to have a teacher like you.
Thank you. Great job.
In the 1980s 90s servo motors like the larger one you showed were used to rotate an antenna probe in the feedhorn of large satellite dishes in order to change the polarity between horizontal and vertical. This position changed from one satellite to another so you would also adjust the skew to get the best picture.
Had this channel existed during my engineering days, I can only wonder how easy my courses would have become. Such great quality videos, I would have felt guilty by not subscribing.
Keep going 👍👍
This was awesome. I've never seen a better in depth, but at the same time quick and concise explanation about enginneering concepts (including the visuals, be it animations or the real things (like showing the signal in the oscillscope)). I'm in 3rd year of electrical engineering, and this has beeen higly motivating, seeing that each thing that I've studied separatelly (working with oscilloscopes, doing circuits, studying the control system with the feedback (the potentiometer going into the comparator)), all coming together in this device, and understanding it well because I've understood the other concepts these past years. It was absolutely awesome, and all because a very well made video.
Seen our new Potentiometer Explained video? ➡️ czcams.com/video/Xb-MZMoUtcQ/video.html
Honestly this was one of the best servo explanations i have seen 👌💯
I love the way you explained the code. And generally every single video you make. It's one of my main sources of learning this stuff. Thank you for the great content 🙂
You answered all my questions that I have for servo as a beginner. Thanks so much!!
Currently a freshman in electrical engineering here. I truly enjoy watching your videos and learning from them! You explain not just the concepts but also how to use and execute them which many other engineering channels fail to do. Thank you for keeping my life interesting.
Recently i've been thinking on how this works, and what do you know? Just in time you published a video about it, i'm All geared up for learning! Thank you, Virtual Professor!
I think you are the first person to spot the all geared up hidden message
Probably due to youtube seeing that you browsed servo shit and then recommending this video. If so, same.
@@hobrin4242 I used to think that way but now I believe they have some weird algorithm to take a calculated guess. This is almost like a magician who knows what you are thinking. Smart guys!!
@@viveksharma9564 I mean it could be that aswell
Haha . Same here.. just completed a project with servo motor.. and got this video
I'm glad you guys stared to show us some control using programing. I worked with the Raspberry Pi and the BBC micro:bit, so a tutorial on Arduino usecases from this brilliant channel is perfect.
I really appreciate the Arduino code explanation in this video. I hope future videos will have the same. Thanks again for a well explained video on electronics. Keep up the good work!
I've used them in R/C cars. Really old R/C's used 2. One for steering and one to run a mechanical speed controller for the drive motor. It moved a wiper arm that would make contact with the appropriate section to send voltage to the resistor to control speed (in a few steps, commonly 3) until it got to the full speed section which sent full voltage. They usually had a section for reverse as well. They were replaced by electronic speed controllers, typically MOSFET driven, not sure when but the mechanical ones were rarely used I got started in the mid 90's.
That is fucking cool. Would the wireless reciever also get it in the variable pulse length format to directly power the servo in those old mechanical cars? If so I presume the servo angle might flicker a little bit
Check out NEW resistor video, everything covered! ➡️ czcams.com/video/DYcLFHgVCn0/video.html

Good video! I’ve been curious about servos for a while. Thanks for the tutorial!
This helps me more deeply understand my RC hobby more. Thank you!
I have often heard of them but never had the occasion to use them. This video is incredibly well explained and even not very long.
Thank you!
This Video Is so imformative, thank you very much. This so helps the people who are new to electronics.
Amaizing explanaition of a very interesting topic! Great video 🥰
I was searching it on ytube.. 10 days ago .. Now it's here....Thanks...
Loved your demonstration of how a servo works!
Awesome presentation, as usual. This thing inspired me to think of where my breadboard is and to start building again...lol.
Thank you so much for these videos and for all the effort and attention to detail you apply to ready them for upload.
Great video! Easily understand because it was simply explained.
Quality content. Thank you for educating me on this subject. Enjoyed it very much.
This principle is used in v.t, c.t heating control valves to vary the hot water output via an actuator. Great video.
Thank you for sharing this knowledge and principles in servo motors & controllers…
Good for beginners. Animations well made. Great work.
Nice video. Many thanks for adding manual english subtitles
I was actually hoping to see you notice and comment this 😅
@@EngineeringMindset Many thanks Paul 😀
Great video. You can easily explain how it works. Thank you.
I plan to build a Robotic Arm mounted in an omnidirectional mobile platform, Mecanum wheels, of course, and Servos for the arm. Great video explaining how Servos work, thanks!
Thank you! It's amaizing explanaition for servo motor video.
Thank you for this nice this is very helpful I'm a 54 year-old dad trying to get a 11 year old boy into electronics we are both learning in these are really good illustrated videos I appreciate
Great explanation and demo. Thanks!
This is so good. Always wondered how this works.
You helped me alot i had to make a report about the servo motor and didn't know how it worked now i know thanks alot! It was really detailed and had a lot of information.
Thanks for the clear explanation. Thanks for sharing. Keep it up.
Really good video. The explanation of the code was a really unexpected valueable info
Excellently explained. Many thanks.
Thank you so much for this educational video, I learned so much.
Thanks, most interesting, I used them on my Radio controlled yacht. I sprayed them with hairspray to seal the joints then covered the seal area with Vaseline. During club races my deck came off in an accident and boat sank. The extra sealing saved the servos
This is a great explanation. Thank you.
Thank you for so nice and elaborate explanation.
Thanks for this informative video.
Great Explanation👌 🔥🔥
Thank you👍
Love the way of explaining code for this...
Very good explanation and super usefull! Thanks a lot.
all geared up! fr though this video is a lifesaver thank you sooo much!!!
Thank you for your videos, awesome work, learned me a lot
Very nice video, thanks a lot!!! 👍
This was a beautiful Explanation
What a great video. Thank you very much
Great explanation. Thank you.
Ith was really helpful
❤
That was a brilliant video 👏🏻👏🏻👏🏻
Ineresting to see how the technology has advanced. We used synchros and servos in Navy gun mounts and also in mechanical (analog) fire control computers.
Very well explained, so much going on in a servo, we use them in R/C vehicle...
Great video. Really helpful for me. Thank you. Cheers 👍😎🇦🇺
This ones very important. Thanks for the info dude. I appreciate what you do.
I used a pair of servos and an Arduino nano to convert an old cable operated snow plow to electric and then used a wireless remote module to send signals to the nano so that when you press for instance the up button the servo operates the hydraulic valve and simultaneously a relay is triggered that turns the solenoid on to run the hydraulic pump. It has left right up and down operating two valves with an open center position and the solenoid operates in all cases except down. This was my first implementation of an Arduino and I was very pleased with the outcome.
Just and Excellent video. I will be watching more.
Thanks again for the videos!☕😎👍🏻🍺🍺🎯
best engineering channel thanks
Really enjoyed the explanation and satisfied with the same
No, not yet! But now i know where to start! Thank you so much✨
Well explained ❤
The best video watched on servo motor
Now that intro was lit 🔥🔥🔥🔥🔥
love this, thanks. always wonder how to make those robots and toys.
I just want it to be known this is teaching my son more about basic electronics than any school
I enjoy your videos very much!
Servos are used in various devices that need precise movement. They're used in every RC aircraft to control the control surfaces as well as retract and deploy the landing gear. They're used in RC cars for steering and in the case of nitro engines they change the gears and control the throttle as well. Open loop servos are sometimes used in model RC submarines to control the ballast tanks. They're used in some configurations of 3D printer bed leveling sensors to deploy and retract the probe. They're also used in walking robots to control each limb.
Great content. Thanks a lot.
Great channel guys 👍👍👍
very well explained
We have a machine at work that uses some servo motors. My bosses want me to learn more about it so this has been a great resource.
i am trying to use the in a small 1:64 rc car, hope to make it work and I will post it. Thank you for explanation @The Engineering Mind! great content
thank you very much sir for this explanation
I use servos on all my model aircraft, they have come a long way from when I started in the hobby.... we now have 1000 in/oz of torque on a standard servo!
Great video!!
thanks for this, you helped me to reassemble a rc car steering servo that i exploded and then taught me a bunch about it at the same time
Great video. I've been working on a recumbant bike that has a small motor controllede by the motherboard that increases or decreases the tension on the pedals in increments. When you press a number on the control panel it pulls the cable a set amount to adjust the tension. I think this is one of these. My motherboard fried and I'm trying to figure out another way to control it, maybe one of these would work. Thanks, Mike
Thank you Sir, good Teaching 👌
The last few years have started to see servo motors used in model railroad applications to change switch points, raise and lower crossing gates, etc.
Great content! This is great for explaining HVAC zone controls. 👍👍
i love how you always 𝓸𝓫𝓵𝓲𝓽𝓮𝓻𝓪𝓽𝓮 every component in the intro lol
Thankyou, that was cool. I'm looking at creating my own servo for my Venetians which I wish I could just throw away.. But more for the fun of playing around with the potentiometer & creating a personalised response is soo cool... I'm just an Alexa newb but having soo much fun with automation lately & super appreciate you're video.. 🖖
Seen our new Potentiometer Explained video? ➡️ czcams.com/video/Xb-MZMoUtcQ/video.html
Thanks Sir very nice information 🙏
When you remove the gears from servos, and need them for other devices, you can use the injection pin (used by doctors), to fit larger gears onto small motors. Superglue is needed, but the gears will fit perfectly on motors. This technique is needed, when you want to replace a plastic or copper gear to steel one, and the steel gear has larger hole diameter compared to the motor’s axis.
Great video. Minor correction on the circuit graphic - the black ground wire is drawn as going into the 5V lane of the breadboard
I use them for the rudder on a large model boat very accurate
Good teaching
These are used to control the throttle plate position in the engine on larger standby generators. Bosch is the manufacturer of many of them. It is commonly referred to as a Bosch actuator. The Bosch actuator is a complete assembly with the servo and throttle plate in the housing.
More vids about servos pls
This was a nice intro. For a followup, I'd recommend explaining PWM and the duty cycle in more detail, but with that real world implementation. Seeing the pulse width on the scope really drove home the point!
@3:03 8.33 kg at 3 cm. The product of length and mass should stay the same.
