Is LIDAR easy to use for hobbyists? DIY Roomba? Obstacle Avoidance System for Robotics

Coupon code: GreatScott19!

In this video we will have a closer look at a commercial LIDAR sensor for hobbyists. We will find out how the sensor manages to measure the distance to objects placed all around it and how we can use this data with a computer and an Arduino. At the end I will then create a small robot which uses the LIDAR system to "crudely" navigate through a room. Let's get started!

Thanks to Elektor for sponsoring this video!

Small correction: The speed of light is of course 299792 km/s, not 299792 m/s. Sorry.

This sensor dosent use time of flight (tof) which would be terrible expensive. It measures the angle of the returning lightbeam with a linear ccd. In the description of the sensor they also write triangulation principle.

How amazing is the communication between the main board and the part that rotate... Fantastic

OMG OMG I was looking for this for so long and finally Scott talk about it.

[pmgodfrey]

Man, you just get a thumbs up for being awesome...and we haven't even covered how smart you are.

I'm always impressed by your videos and I've learned so much. Thanks for taking the time to create them.

Great video as always! To use the Lidar in an easier way, you can use Robotic Operating System (ROS) to handle the data and do the make a program to control it. However, learning how to use ROS is one thing, but once you know it, it's really helpful!

Omg the fact you posted this video after the fact I was think it would be cool to try to make a lawnmower that’s self driving kinda like a roomba, I crazy it’s like you read my mind! Awesome video by the way!

[SleepyCod]

THIS IS VERY COOL. Thanks for making all these interesting videos. I wanted to make one of these myself, this is some good motivation!

Keep up the great work

"Terrible at writing code"
"Limited success"


You and I have very different definitions of "terrible at writing code" haha!

The "stay creative, and I will see you next time!" has been getting slowly more enthusiastic as time goes on.

The only electronics channel to spend time that worth every single second....

[Sekhar_Home]

I watched within few minute but the total viewer at that time reached 5k.. it shows how much popular is ur channel... Keep doing and stay creative., 😀😀
