panther VS turtlebot3

Jetson Xavier computer, Zed2i stereo cam, Livox Mid-40 lidar. Roboteq 2130 motor controller are the basics. The chassis is cheap and simple. A NMEA box some brackets and clamps to mount the motors. All that is off the shelf from servocity.com. Runs ROS melodic. Software configuration is a modification of this repo. github.com/rpanther/panther. The Zed and Livox are fused with Rtabmap to provide SLAM. I should probably write something up but I'm an old geezer almost 69 years old :) Pretty much takes all my energy to keep it working add new stuff and make a few posts a day. I was doing robot demos at the local science museum till covid hit. Hopefully I can get back to that soon.

You could try downloading the package: https://github.com/ROBOTIS-GIT/turtlebot3/tree/humble-devel and just build / run in your iron workspace.

git clone https://github.com/ROBOTIS-GIT/turtlebot3.git -b foxy-devel

To give more context, I am using ROS2 (robot operating system) to build a small mobile robot for hobby/learning. To learn by ready other code, I am looking at a very popular ROS project called Turtlebot3.

You can copy and modify the (turtlebot3)[https://github.com/ROBOTIS-GIT/turtlebot3] repo as basis. They have different robot models for gazibo simulation and starting point for ros navigation.

- if you want to later make a more complicated robot (that uses cameras, has robotic arm etc.) you'd want to look into ROS (robot operating system). If you are in/going to university I highly recommend you join an engineering design team. For an example project you can refer to https://github.com/ROBOTIS-GIT/turtlebot3

The tutorial I was using (which comes straight from nav2) says to run ros2 launch nav2_bringup navigation_launch.py . However, when I went to tune Turtlebot3 via the .param file, it did no change whatsoever. This is because, by default, the file uses up this param file that is significantly different than burger.yaml; After changing it the costmap looks completely different. After reading the source code for the .launch file of the Turtlebot3 nav package for galactic and nav2, I've found out that running ros2 launch nav2_bringup navigation_launch.py params_file:=[PATH_TO_BURGER_YAML] works and completely fixes this issue.

If you're looking for an example of setting the local planner then the turtlebot3 (which I've seen you're using in your delivery_robot_sample package) has an example here: https://github.com/ROBOTIS-GIT/turtlebot3/blob/master/turtlebot3_navigation/launch/move_base.launch
