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.
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.
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.
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.
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.
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.
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
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.
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.
Maybe he just wired everything like in his drawing 🙃😆 well then it‘s rather time to say goodbye to the arduino, not the servo Eventually he will draw the ground wire to it‘s correct position after this comment Oh and not to forget „F“ 😉
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
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.
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!
@@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!!
I knew basically all of the information in this video. However this is a GREAT video. I cannot imagine all of this condensed into one video back in my day. The number of places I had to go to collect all this myself was very hard. So glad future explorers can find all this in one place.

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.
Some minor mistakes, these RC servos use either a DC motor which uses a single H bridge, or PMSM which uses a three phase inverter. The circuit showcased was a inverter meant for what looks like a 2 phase stepper motor. Also the control law implemented inside such a servo is usually proportional control, or proportional-integral control. (Showcased is what seems like a bang bang control)
In aviation industry, Servo motors can be in use of many appliances, like Auto pilot system where it moves aileron, elevator, rudder controlled by AFCS.
How many servos can you connect to one adruino? Can I have the servos move in an already specificated pattern? (If you can connect multiple servos and the second answer is yes) Can each servo move in a different pattern? Do servos need resistors?
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
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.
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.
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.
These servo motors and circuits are commonly used on all modern car heater/AC blender doors. Most all cars have dual passenger/driver climate controls now and these servo motors are used to actuate the doors / vents in the dashboards to control airflow on the passenger / driver side. I have a 2015 Dodge Challenger and you can hear these vents opening/closing. They fail often in this car and I had to replace them twice. Very difficult job with cheap parts from China, but the principles shown here are used.
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!
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.
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!
Two errors noted: the first is the reference of a 9g servo meaning the torque (force) being 9grams. Actually the 9g refers to the weight (approximate) of the servo. Many 9g servos can apply a torque of 1.6 Kg-cm torque. The second error is the 3cm force of a 25Kg servo. It’s not 6.25Kg it’s actually 8.1 Kg (25 / 3).
FWIW: Back around 2004 I hacked {modified} a 180° rotation servo to allow it to turn continuously 360°. I needed it for a KAP {Kite Aerial Photography} rig I was building. At the time I either could not acquire a dedicated continuous rotation servo -- they are readily available now -- or I did not have the money to purchase one. {I already had some 180° servos on hand that I could modify.} I was 43 years old at the time, and it was ALSO when I *_FIRST NOTICED_* I had trouble looking at very small objects very close up. {Trying to see the internal servo bits I was soldering.} Ah, the JOYS of getting OLDER...😊
Such a detailed explanation to get the fundamental details confused. There is no "open-loop" servo-motor "servo" specifically implies closed loop which requires some means of position feedback from the motor assembly to something that can control it based on that feedback. . If it is "open-loop" it's not a servo, it's just an actuator or gearmotor regardless of what Amazon or Aliexpress sellers list it as.
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.
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.
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!
Are there servos for which the pulse would need to be sent only when theres a change in position? These units appear to have a low pass filter to convert the input pulse width into an analog level fed to the comparator.
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 🙂
What’s the difference between the blue servo tester 8:22 and arduino controller 8:43? I noticed that first one turn just 90 degrees and second one 180. It’s because of controller? Why?
I encounter tons of these on portable gensets to keep the prime mover at a constant speed. Its normally attached to the governor shaft/arm through some springs to maintain a 3600rpm/60hz for 2 pole rotors and 1800rpm/60hz for 4 pole rotors
Using two pushbutton (NO) switches to control an Arduino, I use these to control my turnouts on a HO model railroad layout. Using 10 Arduinos, I control 20 turnouts and their associated block lights.
One question: How does the comparator work when there are different max voltages between the PWM and the motor power? I mean in most cases the microcontroller uses 5v logic while some common servos are driven using 9V. In a linear system wouldn't the servo stop at 90 degrees if sent 4,5V (halfway to 9V) since the comparator is equal then even though I know it will move to (4,5/5) * 180 degrees when that happens since that is the scale of the PWM. Just curious about the circuit. Thanks for the video!
Anything that demands positioning. In HVAC, you can find some closed loop servos hooked on air dampers, however they often take 0-10V or 2-10V signals instead of pwm.
I used to take the motor out of a servo and attach a female JST to the motors wires then box it all as neatly as possible. Then attach LEDs with male jst. Then playing with the servo pot and trim of ch3 on rc radio. Ide eventually set it right and have remote lights off ch3. They had 3 modes too with a 3way switch on ch3. Off low and high. Reverse the channel 3 and they strobe. Best use for any futaba s3003 but they a pain to solder on the jst. The clear blue cheap as servos were the best small box. Cheap and the motor had wires so was real easy to attach the JST. Diy rc light controller. I had ideas to make a tipper bed truck using a servo or two with its stopper taken out so the motor can spin one way or another. Have a spool servo horn with fishing line. Then make the truck bed and attach it however it goes on. Then add springs to pop it up. Now activate the servo to wind in the fishing line lowering the bed. Turn the servo the other way reverse ch3 mayb then the line will give slack letting the springs raise the bed. Same idea for a diy winch too.
TY! This is really helpful! I want to make a 360 solar tracker. My main question is how long do these last? Can one be made that can reliably last 30 years?
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

Correction: 25 kg.cm at 3 cm is 8.33 kgf, not 6.25 kgf. The latter occurs at 4 cm, not 3 cm.

all geared up! fr though this video is a lifesaver thank you sooo much!!!
This was a beautiful Explanation
I used to take the motor out of a servo and attach a female JST to the motors wires then box it all as neatly as possible.
Then attach LEDs with male jst.
Then playing with the servo pot and trim of ch3 on rc radio. Ide eventually set it right and have remote lights off ch3.
They had 3 modes too with a 3way switch on ch3. Off low and high. Reverse the channel 3 and they strobe.
Best use for any futaba s3003 but they a pain to solder on the jst.
The clear blue cheap as servos were the best small box. Cheap and the motor had wires so was real easy to attach the JST.
Diy rc light controller.
I had ideas to make a tipper bed truck using a servo or two with its stopper taken out so the motor can spin one way or another.
Have a spool servo horn with fishing line.
Then make the truck bed and attach it however it goes on. Then add springs to pop it up.
Now activate the servo to wind in the fishing line lowering the bed.
Turn the servo the other way reverse ch3 mayb then the line will give slack letting the springs raise the bed.
Same idea for a diy winch too.
This principle is used in v.t, c.t heating control valves to vary the hot water output via an actuator. Great video.
TY! This is really helpful! I want to make a 360 solar tracker. My main question is how long do these last? Can one be made that can reliably last 30 years?
Seen our new video on HOW SOLAR PANELS WORK in detail ua-cam.com/video/Yxt72aDjFgY/v-deo.html
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
Bonjour merci pour la vidéo. J ai commandé par erreur des servo 360 puis je les convertir en 180? Merci
Excellently explained. Many thanks.
By the help of this can I rotate a gas regulator pin automatically?That we are daily adjusting manually. At 5 am we rotating the pin clockwise direction for increasing the gas pressure to the locality and at 9 pm we again rotating the pin anticlockwise for decreasing the gas pressure to the locality during night time
