Getting Started with LIDAR

[@hemotors2519]

what you explaining is very clear, and we are the manufacturer of the LiDAR motor in your LiDAR device. Wow, I am really proud of that.

[@jorgeferreira6727]

I use a small trick with those RGB LEDs to get a clear full color range for photos , motion picture and even for the nacked eye view. Cover the LED with a tube of white paper. You get a better color mix due to the diffusion effect of the paper and the camera sensors won't saturate with excessive glow. I usually extend the paper tube one or two centimetres above the LED top and get a nice color stick.

[@RogerElliott_SysGuru]

Hello, it is great these are so inexpensive now, I used a LIDAR 8 years ago which cost around $1,000 and only covered 240 degrees. 33:12 Shows MOTOCTL connecting to PIN 2, but it should be PIN 3 for PWM. The voice over is correct.

[@codecage9333]

I noticed the same error Roger! But in the example Arduino code it shows MOTOCTL on pin 3, so the astute students should have no problem catching and correcting that issue.

[@BarackBananabama]

This guy is an amazing teacher!

[@emptied-soul6105]

agreed!

[@pipercolt1963]

Rather than get sucked in by this conspiracy guy commenting here, I am an electrical engineer and we'll tell you this has got to be an education as they say! Not knocking school just saying however you can learn a lot from the dronebot.

[@ChadForquer]

If he wasn’t so interesting his dry presentation would not be good. The great thing is he picks interesting topics and doesn’t dumb it down to much or make it to technical.

[@BillAnt]

This guy's shop is too neat, you needa messy shop to do great work. he-he just kidding!

[@stevendam8031]

ofc!

[@ieduardoms]

You are the first source I use in order to know how to use electronic devices. Great explanation. Thank you very much.

[@batkanova6736]

He explained clearly absolutely.I learned what Lidar is and how lidar is used how lidar is programmed.Thank you very much.I love you.Quality of video is amazing.

[@rpuskarcik]

I enjoyed your demo. I think your information is very well communicated. You were correct about the TTL logic detecting a high (1) at above 2.0v (not 2.8v), which is true for all families except CMOS. However, logic lows (0) must be below 0.8v, not just below 2.8v. A simple solution to reducing 5v to 3.3v is to us a zener diode (1N4614) in series with the TTL output and the 3.3v input.

[@Hamad.Kuwaitt]

You are Professor in the delivery of information in all simplicity 👍

[@acopernic]

Bravo. I think I will use this for my motorcycle to 'see' what's going on behind me but I will test if I can hide part of my motorcycle (to see 180 degrees only). Thank you for this brillant video.

[@talakael5601]

here use this for your motorcycle instead kzbin.info/www/bejne/hXzTi6Skq9aLarc

[@harrychew6359]

@@talakael5601 But he wants to make it himself? XD

[@MichiganPeatMoss]

As an prior electronics enthusiast, I'm here because of the article on 3D scanning of the Notre Dame cathedral, in lieu of the fire in Apr 2019. Excellent introduction to LIDAR and relevant affordable devices of present day. Thanks!

[@chrismofer]

someone definitely needs to make a system where one of these scans / sweeps an area and stores the points in a known point cloud file format so that they can be opened in 3d software and meshed

[@stevensheldon9271]

This is one of the only TF LIDAR tutorial videos that mentions that you need a 3.3 to 5 TTL converter. I did not even know about such things until this video. Thank you so much! I would have hooked up my LIDAR to my Arduino and possibly damaged it.

[@BADALICE]

These videos are just amazing quality. College level courses. It does not get any better.

[@abdraoufx]

It's amazing how arduino opens so many possibilities.

[@robertst-laurent6452]

Like all of your videos; masterpieces learning tools. You master a very rare talent of teaching complex subjects and making those pure and precious moments of enrichment of knowledge. We now live in a ‘da Vinci’ world of creativity available for all at home where you can get some of the very best CAD tools for free. It is people, angels like you that are giving us this new era, this "da Vinci world of creativity and inspiration" where true happiness in life is giving it to others first.

[@Harsh-oo6bg]

You Sir are serving the world, would like to support your content in future.

[@stevenlee1726]

I can listen to your lecture all day longggggggggggggg. Very clear explanation and straight to the point

[@Longtum]

I have watched your video for serval years. Your videos did help me become from a pure software engineer to a hardware engineer as well. I appreciate it. I am living in Toronto, are you live in Canada too. 😀

[@Dronebotworkshop]

So glad that my videos have helped a fellow Canadian!

[@namero999]

Oh brother, this channel is a pure gem... Thanks for the amazing work. Also those custom wall outlets are amazing :D

[@pasanlaksitha]

if you are using premiere pro to edit your video, try denoise your video with audio denoising . and you're an amazing teacher to teach people!

[@dompower500]

Hi Sir. I am always following all of your youtube classes. All are excellent. Your teaching method is very simple and very easy to follow. It's easy to follow even by novice. Thank you very much sir. Expecting more from you. Pls be safe from covid-19 too.

[@daled.4495]

Guys, I'm not into robotics, but this guy is amazingly thorough and knowledgeable. He makes something that can possibly be construed as complicated look simple. As I said, I'm not into robotics, but damn he's good!

[@markhowell25]

Thanks, now I get it. Perfect explanation and easy to hear, “no mumbling “.

[@aghidalgo]

Es usted el mejor profesor de electrónica de la historia. No cambies nunca.

[@TheSulross]

there are a number of good channels that do tutorials on tech subjects with decent, knowlegable instructors, but am thinking this channel is perhaps at the very top in so far as clarity of the instruction, the pacing, and interest aspect of the topics covered

[@DAzZuLK]

9:20 just adding to your description. It is adjusted to one temperature/air pressure. I use it to show my students how the speed of sound gets lower at higher temperatures (using a lighter between the path of sensor and object) and seeing how it measures a higher distance. Obviously with the math included. Thank for another awesome video!

[@zaphodbreeblebrox9542]

Optical Source Sensor Arrangement can be pointed downwards at floor in front of your robot to detect stairs. In that case, apply brakes when the voltage drops!!! :-) Fantastic description of Lidar. Thank you so much!

[@مييناحمر]

Hi Sir. I am always following all of your youtube classes. All are excellent. Your teaching method is very simple and very easy to follow. It's easy to follow even by novice. Thank you very much sir. Expecting more from you.

[@yellowboxster06]

Great job as always. I appreciate your technical discipline (on color coding, logic levels, etc) when interconnecting devices for demonstration. I look forward to your videos particularly on LIDAR applications. I was actually one of those military guys, way back when, trying to figure out how do make best use of LIDAR for remote sensing and target classification. At the time we were living with the common notion that RADAR was only marginally effective in any given application. We needed better resolution and LIDAR looked promising despite some obvious limitations. Fast forward to today's technology and here we are experimenting with low cost devices that are eye-watering in their capability.

[@danielash1704]

Back up camera software for the purpose of windowing a zone detecting in it. The basic security cameras have zones of activation of motion alarm systems most will have a hard wired sockets to screw down to sensors or lidar tab tip.

[@foobarmaximus3506]

So you were a truck driver then?

[@nettyvoyager6336]

what is amazing ! is your workshop a true testament to you're commitment, without the interference of a wife, she must love you, as much as my wife loves me, hence my spare room is now a workshop :)

[@daled.4495]

Your workshop is so organized and clean. Impressive!

[@ImpeccableWizard]

Happy to find your channel, you explain well and is not dragging out the explanations in long ramblings, nor does you bore me at all and seems to have a natural takent to make micropauses long enough so that one can let the information sink in. Just a little nitpicking; at 22 minutes in you say property, I would like to say (getter) method ;)

[@Scriven42]

Underrated hint about the white- and colour-balance focus-"dummy" of yourself @28:45 ish! Fantastic idea!

[@stetiennealain7504]

Very good demonstration and education

[@victororo462]

Thank you for the video! The software that comes with the 100 unit is basically all that I would need when I'm out in the field. I've been needing a tool that would allow me to see in complete darkness out in the forest. I have animals that approach me while I'm in my vehicle. I've attempted ultra sonic sensors mounted on servos that sweep back and forth. Much too slow and thanks to the servos, far too noisy. I cannot wait for this! Thank you again for this informative video! 1 million Thumbs Up!

[@AgentOffice]

You might like time of flight sensors

[@mutalasuragemohammed6954]

Love your calming demeanor. Explanation superb, and your practical very practical.

[@ScootLogix]

I really enjoy watching your videos. Great balance of explanation/theory, real world use and coding with explanations.

[@INSTRUMANROBOT]

This is by far the best LIDAR intro video I have seen and I have seen quite a few. Thank you so much!

[@tvnsi8556]

Thank you for great job. You are teaching me not electronics only. You are teaching how to teach. Your trainings like standard meter in Paris ))

[@johnharper9829]

I just got an RPLIDAR, and wanted to know what to do with it. Thank you very much for your easy-to-follow teaching style!

[@isaactavares1767]

Thank you for this excellent video. If you are also a teacher, then your pupils are very lucky ones.

[@mobius-1965]

I have desided to become a lidar super freak,I have tons to learn but I am at the right place this gentleman and I will learn his name sorry is a very good teacher therough but not boaring and sticks to the subject I am so exited I ordered the starter kit I regret already not getting the expedited shipping already haha.

[@skiltonable]

Excellent demonstration. As an introduction, the detail and pace is very good. Many thanks.

[@666marsipulami]

Real great explanation of different modules you can use with Arduino. I just love these videos from him. Thank you very much! Great work!

[@mrcalico7091]

Great Job again! Your presentations are always so clear, concise and complete! I'm glad I found you're "Workshop" page!

[@Rampuniernix]

explaining speed, visualizations -very well done! thank you so much!

[@TechDriven365]

This is the best explanation of LIDAR that I have had to watch. amazing work, sir.

[@omarobando8273]

Awesome tutorial. I love the straight forward detail explanation and visual, it makes it a lot easier to follow. THANK YOU very much.

[@Sembazuru]

A use case for something like the RPLIDAR that I've wanted, but lack the skills and time (to learn the skills and execute) is a self-driving robot that navigates around a house and then is able to output a dxf drawing of the floor plan that it scanned while it drove around. So it would need to navigate and decide where it hasn't scanned yet (similar to the NeatoRobotics vacuums knowing where they haven't vacuumed yet) and then use all the scans to super sample an accurate point cloud that it then converts into dxf lines and arcs.

[@belspace]

This guy rocks! His explanations are crystal water clear !

[@eduardo33]

Only one thumb up is not enough for your work. Congratulations !

[@grateful4068]

I really want to get one of these for obstacle avoidance for a DIY auto-mower. So cool.

[@pca.makesting]

Thank you sir for giving this fantastic explanation... I need this so much!

[@RufusVidS]

I love all your videos! My current job will be using lidar, and your video is excellent introduction, and your love of the technology and sharing your knowledge is so evident in your videos!

[@furiousangels6222]

Brilliant review, 45 minutes on LIDAR. 😎 Plus all in an easy to understand method, deserves much more credit for this Video!! Will be checking out all your other videos now too.... 👍

[@joelabranche3251]

We use LiDar as a surveying tool. I just started playing with the Arduino for fun. However, what I see here is the marriage between them is quite exciting, thanks for a great lesson.

[@MrDrew32xx]

Playback speed 1.25 . Perfect 👍🏻 Great tutorials thank you

[@climbeverest]

This is exactly what I was searching all over for, and google searches would yield ready made devices like uniden or other brand radar detector ready made, instead of just the sensor and interfacing documentation

[@therealhustle7808]

wow, this guy really knows what he's doing!!

[@fluxoff]

I"'ve been waiting a long time for these devices to be created & sold. Thanks ever so much for the demo& sketches!

[@phanokesak5099]

Thank you very much, and "what a very progressive educational approach..." I haven't even seen the whole time passing. There are some awesome people like you out here. Thanks

[@KSBallvardhan-n3v]

Sir I want to know everything about optical source sensor arrangement pls...Thank you

[@LarryGreen]

Thank you so much for the step by step instruction and also the background and reasons for tasks performed. I am currently working on a project that has 6 steps, I wish to add a interrupt that would trip in the event of a safety proximity sensor being tripped, yet upon resuming, to return to the exact point where the interrupt took place in the 6 step process, any assistance that you could provide would be great. Thank you again for all that you have offered.

[@Atka59]

Well presented and clearly explained in a logical fashion, with excellent diagrams as well. Awesome! I suspect that a lidar will be in my future, it is just too interesting to pass on. Thank you.

[@toriless]

He has it go to pin 2 not pin 3.

[@overmanonfire]

You are just an Awesome person wish a lot of people were as you are

[@vic64583]

Thank you!! Your code and explanation helped me to get TFLuna work!!!

[@TheRealStructurer]

Have been watching many of your videos (and subscribed!) and follow your experiments/teachings. You keep it straight to the point and I like that you often give us a bit of background like U did with this one about the Lidar. Keep up the great work!

[@apbosh1]

great introduction to lidars really like the way you explain things. Thanks. subscribed.

[@mhelvaci2156]

Just exellent job what your are doing, great expression ability and clear technical definiton for even dummies. Thanks a lot

[@winstonsmith478]

A buyer of this on Amazon says this is worthless outdoors despite the outdoor range claims in the manufacturer's manual. This is understandable since this uses a focused IR LED and not a laser. It's like trying to use an IR controlled aircraft outdoors - too much IR noise from our local star overwhelms any reflected signal . His comment: "I tried 2 of these hooked up to an Arduino Nano and also a laptop running their code. Range outdoors is about 3 feet. The best I ever did was 7 feet and this was in the shade. Please note it will not read distances less than 1 foot and when it errors it can put out some big numbers. bottom line is it works indoors ok. Outdoors forget it..."

[@BADALICE]

This could be used for targeting. Thank you. love it.

[@urishani]

sounds great also with 1.25 and 1.5 speedups... ;) love these tutorials. great quality and informative.

[@anguswoodman8289]

Love your videos. A great episode would be if you could run though how to use the RPLidar for SLAM

[@victor.kopsch]

Iam watching all your videos and i enjoy treaty much til now. Keep it up your excellent work.

[@kotgc7987]

Beautiful workshop organisation. LIDAR is captivating, however I think I need to focus on camera optical recognition.

[@RupertBruce]

That last RPLidar experiment reminds me of the Theremin. You could build a musical instrument controlled by the Lidar sensor 😎

[@brad3035]

On the RPLIDAR diagram The MotoCTL pin should go to Pin 3. it MUST go to a PWM connection and 2, which you show it going to at 33:04, is not a PWM output.

[@johnsmith-oy9kx]

You are an amazing TEACHER ! The best LIDAR Tutorial...

[@sirskeptic]

Thanks for this. I recently has a project where I needed to detect a persons height when they walked under an SR04. Apparently heads absorb ALL sound. The SR04 detected hands, books, hats bit was completely and consistently blind to heads.

[@barrycrowder]

Excellent video. It's not easy to present so much detail about a complex issue as LIDAR in such a well organized way. I particularly like how you introduce your subject and what you will be talking about, then how you show as well as tell. And your use of text and graphics is top notch. I've definitely added LIDAR to my list of technologies to explore based on this video. I'm subscribing based on your excellent production value.

[@spicesmuggler2452]

calm down Barry

[@EvileDik]

Hitachi make a very cheap SLAM component for manufacturing things like robot vacuum cleaners, there isn't a lot of data available at the moment for it, but you can pick up a HLS-LFCD2 for about £30 in the UK. I'm currently working on an arduino library for it by reverse engineering a linux driver I found.

[@webslinger2011]

Great! Hope to see more of these videos. How can it be used to detect and avoid obstacles on a robot.

[@alexanderstohr4198]

you should always start to connect your devices with GND - and disconnect those wire last when disassembling your setup.

[@srinivasancheenu1908]

very informative ....a clear and crisp explanation

[@fsiserir]

Thank you very much for explaining the basic principle of lidar.

[@tteffom]

Great Tutorial. Just one comment, in both the narration and the actual sketch for the larger LIDAR, you comment that you are connecting to pin 3, but the diagram shows connection to pin two on the arduino (at point 33:07 in the video). Note this might cause confusion - especially as pin two is the interrupt pin, and (as far as I recall) not the pwm pin.
