F1tenth (F1/10) Lecture 9] ROS Transformations and Coordinate Frames

[@commanderbensisko]

In 2 years on a robotics masters degree I have never had this explained to me so well and clearly.
Thank you Sir.

Thanks for sharing this video. Has been useful for my self learning and resolved some doubts faced during my own designs

Hello Sir, do you have any plans to teach this course online? Your lectures are great explanations. I'm also studying Robotics & Control Engineering in Myanmar. Thanks for your videos.

[@madhurbehl]

yes, planning to upload each week

Thank you so much for sharing!! Just one question, if I have a transformation tree map->odom->base_link->laser_link, should I associate base_link with map or odom? I mean, I have the odometry info, so it is correct to say:
odom_msg.header.frame_id = "odom" and odom_msg.child_frame_id = "base_link"
or
odom_msg.header.frame_id = "map" and odom_msg.child_frame_id = "base_link"
Thanks in advance!

The REP-105 can help you here: www.ros.org/reps/rep-0105.html

I'm facing a very similar scenario, how did you solve it? Are you using the odometry pose estimation to fill in the map->base_link or somehow dividing it into map->odom->base_link?

[@SudhirYadav-kz6ts]

Associate base_link with Odom. In case when Odom is same as map it will have no effect, but in some cases odom might be different from map. Thus this definition will work with both cases.

Sir how can we do leader follower formation in ROS2 basically in turtlesim with help of code?
