look Amezing , what a clear cut of words congratulations looking forward more like interfacing lider then stack navigation then ros control . keep doing
Hi man, I think it is too late, but what incredible video. You should keep doing these kind of videos. Excellent !!!!!! I would like to know how do you program the lidar.
Hi, the robot looks cool. Could you provide some resources from where I can learn about the electronics part of robotics? Your help would be greatly appreciated
Also, I have 2 more questions: 1. I wanted to know how I can use python instead of C++? 2. Can the bot work without the use of the encoders? I have an RPLidar, and in the past, I have been able to use SLAM by also realizing its pose estimation and localisation, too. I am hoping to use just that instead of encoders. Just not sure how.
Yes, You can impliment it without the use of encoders and use Hector slam. But without encoders, it is difficult to control the direction since the motors are not always accurate.
HI., thanks for the great content.,., I am working on RPLIDAR based hector slam.,., i am missing in integrating with gpio and motor connection part also to serve predefined map to localize to particular location., can you help or post new video on this??
hey great project u have built here. can you tell how u have learnt all these various concepts, like ROS, rasberry pi and all. Please suggest me as im beginner.
Thanks for sharing. I looked into the differential_drive ROS package. I found the twist_to_motors node and pid_velocity node also. If I use those nodes, I don't need to implement PID in the Arduino sketch, right? Is there any specific reason you didn't use them in this project?
Why do you need to use both a raspberry pi and another computer with a ros installation and a ws? cant you just SSH into the PI through windows and start scripts that way?
Right now I've used a Raspberry Pi 3B and a laptop together over wifi because I wasn't sure that the Pi 3 can handle the navigation stack. With a Raspberry Pi 4 or any other powerful SBC, you can completely power it offline (i.e. without WiFi)
How did you use the teleop with the hardware of the motors? You wrote a code using arduino for making the wheels work, but then directly launched the teleop through the rpi. Did not understand that part.
Great video up to the point of trying to clone differential-drive. The link in your comment went to the hardware code...no differential drive. The github clone in your video did not exist. Since this is an essential part of making this project work, where can I find the differential-drive github URL?
demand_speed_right = demandx + (demandz*0.1075); in this line, you used the formula you talked about in the video. Do i have to change the 0.1075 value according to my robot's length? Thanks
If you're comfortable with working in a terminal environment I'd suggest using the ubuntu server. I'd also suggest going for a ROS Master-Slave combination as you're using a kinect and that takes a lot of resources.
I faced the same problem. The code in github publishes to /speed which is not yet updated. Please make changes to the arduino code by carefully following the video so as to publish to /lwheel and /rwheel topic.
@@pranavshevkar269 Thanks a lot for reply,what is the next step of this video to do mapping and autonomous navigation.Do we need to write more scripts? Can you tell me steps to do mapping and navigation.I mean if we clone gmapping and move_base packages can we do mapping and navigation? And i read in gmapping documentation that he needs a transform from laser to base_link(fixed),how can i do that. Thanks again.

Hey, I'm sorry for the delay. I'm a final year student and the final semester project workload is keeping me busy :/ The project is over and the next video is being filmed but it's taking longer than expected :(
@@vinaylanka Bro can you share video part 2 coding of Ros and Arduino......in git hub the Arduino coding is different from coding you have shown in video...pls help me bro I am currently working on mobile robot
