Күн бұрын

Welcome to Part 2 of making an Autonomous robot from scratch using ROS.
This ultra-long episode covers a lot of stuff. We finally finish writing the Arduino sketch for the hardware. We briefly understand what ROS is, why it was formed and how it works. We look at the kinematics of a differential-drive robot and implement the differential-drive package in a ROS workspace.

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?

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?

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.

@pranavshevkar269 2 жыл бұрын

teleop_twist_keyboard publishes to /cmd_vel topic. In the arduino code, it is subscribed to this topic and the message is decoded to move the motors.

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

@pranavshevkar269 2 жыл бұрын

Yes, you have to change that value according to your robot geometry. After calculations it is equal to (distance between two wheels in meters)/2

Bro which is better to have ubuntu server or ubuntu desktop running on raspberry Pi ? I'm using kinect for mapping

@vinaylanka 3 жыл бұрын

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.

Ros robot needs wifi to function after complete? Or offline as well?

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)

odom just revolves around base_link,what is the reason?

@pranavshevkar269 Жыл бұрын

In RViz, make Odom as the fixed link

@ssaniljainn 2 жыл бұрын

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.

@pranavshevkar269 2 жыл бұрын

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.
