Robotics Programming: PID Algorithm - Wall Following and Balancing
Today's episode of Robotics Programming is a special one, we will learn how to write a PID or Proportional, Integral and Derivative controller. In this complete guide to understanding PID we will breakdown the Mathematics, give step by step examples and see it in use! We will apply it to solve problems in robotics by showing how it can be applied to create both a wall following robot and a balancing / standing one.
This versatile algorithm is a staple not just in robotics programming but in many engineering disciplines and is the go-to method so solve many problems. We will discuss each of the 3 components of the PID controller, there relationship to each other and the overall outcome and...

Robotics Programming: Servo Control for Arduino
Просмотров 3,7 тыс.3 года назад
Today’s episode of robotics programming explores fine servo control. We are going to combine a servo with an ultrasonic sensor to enable our robot to "see" obstacles at various angles relative to the robot. First we assemble the components using a breadboard. We see how to use the battery power combined with a capacitor to ensure that the servo has enough juice to move. After completing the har...

How Do Computers Save Data? Part 2: Encoding Sound, Images and Video
Просмотров 4083 года назад
This video takes an in-depth look at how computers can save sound, images and video from our analog world at large as digital data. We explore how analog sound waves are preserved digitally by measuring the amplitude or hight of the wave at discrete intervals. Then we explore 2 methods of translating visual information into digital data, bitmap and vector images. Finally we discuss how these im...

Bro this is Gold.Thanks Man❤❤❤❤❤❤
Pretty useful stuff. Thanks for sharing.
Thanks for the (surprisingly) interesting intro to these CS topics!
Please teach me how to program
I was following everything up until when you introduced the fourth relation and crossed off the first one. I understand that F is one of our keys and thus, R4{F} in addition to the offender I so R4{F, I} but where does the G come from? And why isn't H included in this new relatioon?
I'm in a robotics class and I HATE MATH WITH A PASSION. But this video will come in handy. I definitely will save this to my favorites. Thanks! 😅😅😅
Hi, thank you for the videos. I can’t access the slides though!
Great presentation. Very helpful when trying to understand best practices with prepared statements.
W video gang
Thanks man <3
Better than my university professor. Much appreciated!
The PowerPoint slides are not found..
this is so helpful <3 thank you you have saved my exams
I try to add the time of flight sensor opt3101, thanks for your example, lets see what i'll come up with :)
HI, glad to have discovered tis channel, i have started my journey into robotics and automation and i believe this is the best place to start. thank you so much for your content , i am looking forward to learn a lot. meanwhile what i seem not to be able to connect with your website. is it working?
Excellent explanation, thank you very much. Can your share the presentation please? It's a great material. Thanks in advance
@coding Coach, please provide us with the source code
thank you Sir helped a lot
Can you please make a video about when the distance from the wall is not at 90 degree angle?
The physics of the modern nano-scale CMOS gate really requires advanced solid state physics along with a background in quantum mechanics... Its hella complex.
Amazing video.👍 Can I get the slide for future reference? Unfortunately the shared drive link is not working though
What would someone have to be doing, and how much knowledge do you need to have accumulated to come up with such a simple yet robust algorithm? Hat's off to the one who came up with it. Best explanation of the algorithm I have ever seen. My search for this explanation officially ends here. Thanks man!
Really interesting video. Do you suspect the power efficiency of the M1/2/3 is more down to the adoption of RISC or the emphasis on high IPC and relatively lower clock speeds?
this pokemon (kindaa) music hooked me as well as explanation ofcourse :)
Thank you for the video, I learned a lot
i'm sorry, i want to ask you a question i want to make an open loop for my robot humanoid, but i confused about how to make the algorith can you teach me to make it?
Apple isn't constrained to using an industry standard architecture because they control the whole stack. And because of that people like me will never buy an Apple product. I control my whole bank account. I won't even spend a penny on Apple + video.
thank you so much sir.
Thank you. understood well
I'm sorry, i want to ask, from this explanation about PID, can it be applied to humanoid robots?
Very, very nice!! What do you think, is it ok to use PID regulator for line following robot? I have 4 line sensors.
wtf is this man talkin
Thank you, weirdly enough my University demands this knowledge for the upcoming exam without explaining it :o
16 GigaBYTES not BITS.
Please say in hindi.
I'm watching this to try to build a simple cpu in minecraft lol
same
I took this course at community college, taught by a professor who should have retired five years ago. He's a great guy, but we never really connected the dots in terms of Organization and Architecture Concepts. I'm super grateful to have access to a GREAT free course like this ****so that that I can be confident that I've received a CS education.
Caching is also a method of circumventing the von neumann bottleneck, right? I mean, I get it like this: Modified Harvards provide a compromise between the mutability of the JvN's program data and the speed+security of a pure Harvard
your videos shows clearly that you have real experience and know what are talking about not like my professors which just read form the slides without explaining anything. I can literally read the slides at homes smh
Oooh gotta dislike just for Discovery. It’s the worst one haha. Jk any Trekkie gets a like from me - but still rethink your life choices 😂
what is the voltage of the battery?
Could i use big motors? Because i want to use big wheels
You are a very talented teacher. I found your lessons extremely valuable, my only disappointment is that you did not continue. I hope that you will revisit your channel, because I'm certain that you could build a large following in time.
Nice video!! But why did you stopped uploading new videos?
Where is the navigation algorithms explaintion (A*,potential field) ?
I've been programming for 43 years and rarely do I find such a clean, straightforward explanation. So many examples use this, but the syntax has confused me. You cleaned all of that up for me without any confusion at all. All the syntax I've used in a rote fashion makes total sense to me. Thank you.
The link for the slides used no longer works.
Thank you so much
great videos, got really excited when i saw what else you were planning on doing (including potential field), been a while since there have been any new videos though, is there anything in the pipeline?
