Can you make a video about the whole process of applying SLAM with a laser lidar?
Thank you so much!!
I'm a Korean student, and I was in trouble..
But you saved me. Thanks again!!
I'm glad you found this useful. Thanks for watching!
you are such amazing help to me, i am a beginner researcher in robotics and your videos are so helpful.
Thank you for the kind words, and thanks for watching!
I have to use rplidar to detect human in a indsutrial field. So rplidar will be placed in a fixed place. Can you tell me how to achieve this? I guess i have to do the environment mapping which i have done by using ros heltor slam. But dont know what would be the next step. Can u please give me some ideads about how to detect the obstacle after got the environment mapping
Hi Jim! It's wonderful tutorials. I have a problem with connection between RPLidar and Jetson Nano.
I connected RPLidar and Jetson Nano. I used "usb-devices" and I could not see "Product CP2102 ..."
Do you know what problem is?
Thank you for the kind words. I do not know what the issue might be. Is it possible that your RPLidar does not use the CP2102 chipset, substituting a chipset with similar function? Thanks for watching!
Awesome video, You help me alot!
any Ideas about how to by using the RPlidar in vertical configuration , get some 3D map from a room while the robot is movig throught the room?
I do not have any experience using it in that type of configuration, so I can't really give you an opinion. Thanks for watching!
love your videos
Thank you for the kind words, and thanks for watching!
Very cool going to buy a jetson soon. I want to train neural network to interpret lidar shapes
Sounds like a fun project! Thank you for watching.
Cool video!
Hello do you use the RPLidar or the Hokuyo more?
I use the Hokuyo more often.
What is this awesome music at the beginning and the end of your video?
Thank you for the kind words. Me and a couple of friends were jamming one Saturday afternoon with the recorder on. I liked that particular "song" (it's just basically an improvisation for ~ 20 minutes), so I grabbed it and use it as an intro. Thanks for watching!
Perfect tuto ! Lov u XD
Thanks for watching!
What’s the cheapest and best way to 3D map a room with the jetson nano?
That's a pretty broad question. Please ask this question on the official NVIDIA Jetson Nano forum where a large group of developers and NVIDIA engineers can share their experience. Thanks for watching!
Great video
Thank you for the kind words, and thanks for watching!
Thank you for that but what about next step , there is no info about how can I use these laser scan output or hector slam output to make an autonomous drive
Not quite sure what you are looking for here. There are ROS and ROS 2 packages available from Slamtec for these lidars. This allows you to use the lidars in conjunction with other ROS packages, such as Hector Slam. If you are not using ROS/ROS 2, then there is a whole other set of questions you need to answer. Thanks for watching!
What is the typical expected service life for such rotating lidars, as mechanical wear could shorten thr lifespan
Depends on the lidar. You should read through what the manufacturers have to say about the subject. Thanks for watching!
Hello Jim! Where can I download the racear-ws directory?
You can follow the directions on f1tenth.org. The racecar-ws is a ROS workspace.
@@JetsonHacks I'm sorry, but I don't know what to follow on this site, can you elaborate a bit more?..
@@man5066 They have a Github repository and instructions. See: f1tenth.readthedocs.io/en/stable/getting_started/driving/drive_nx.html#nx-setup for example.
Hello Jim ! Im trying to make this project with Jetson nano and ;
Error, cannot bind to the specified serial port /dev/ttyUSB0
How can i solve it ? Thanks !
Did you list the /dev/ttyUSB* devices?
@@JetsonHacks Yes and I've followed all the steps in this video but it dosnt work in Jetson Nano..
@@cengiztezel4576 And what did the /dev/ttyUSB* devices say?
Does this work the same for jetson Nano as well?
It should.
is that rp lidar available for arduino? im have an trouble for it
I do not know. I do not know what issues you are having.
@@JetsonHacks I'm Have a final projcet about make a 2D Map using rp Lidar based on arduino and show the map in Microsoft Visual Studio C#. But,,,,Im have an trouble with connect between arduino and visual studio c#. Can you help me?
Interesting l! Thank you )
You are welcome. Thanks for watching!
Hi, I'm working on the prototype of autonomous car. As I want to avoid obstacles using RP-Lidar A2 M8. But I want to do that in Python. As I have seen some values coming. Can you tell me how I can sort out distance values of when an object come in front of lidar? How to know? Which values will tell us? Also that object coordinate like size, width etc. But SDK is written in C++. Can you tell me other way or suggest me some tutorials. Thank you so much if you can help me.
Not sure what you are asking. In the rplidar_sdk there is the ultra_simple app which prints out the data received from the device. You get back the angle from the device being measured, and the distance to any object encountered. The angle will tell you the direction of an object in relation to the lidar, and the distance to that object. You will need to gather consecutive angles to determine the 'width' of the the object, remembering to correct for the circular nature of the lidar sweep. Good luck on your project!
@@JetsonHacks Thank you so much dear. What I want to tell you, It's simple to understand that I want to implement obstacle avoidance algorithm on RP-Lidar A2 M8 using Python language. And I want to sort out the accurate position of an object to avoid. But it's SDK is written in C++. Can you help me by telling availability of python libraries and please suggest me some tutorials. Thank you! :)
@@ansjaved3484 Dear, please search Github for 'RP-Lidar Python' where you will find many Python libraries for the RPLidar. Good luck on your project!
@@JetsonHacks okay cool. 👍
@@JetsonHacks dear, I have run SDK (./ultra_simple) demo, but Lidar is continuously running. How can I stop it?
