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.

[@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!

[@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.

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.

[@Hamad.Kuwaitt]

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

[@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.

[@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

[@namero999]

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

[@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.

[@BADALICE]

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

[@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.

[@abdraoufx]

It's amazing how arduino opens so many possibilities.

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

[@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.

[@Scriven42]

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

[@mrcalico7091]

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

[@eduardo33]

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

[@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?

[@markhowell25]

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

[@stevenlee1726]

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

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

[@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!

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!

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.

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.
