4. docker exec -it ros bash
5. cd root/ROS2-Path-Planning-and-Maze-Solving/path_planning_ws/
6. colcon build
7. ros2 launch maze_bot maze_1_robot_camera.launch.py
   or
8. ros2 run maze_bot maze_solver

Expected behavior: Without error and runs properly

Description

Following the steps on 4. Guide 1 Base setup
When I try ros2 launch maze_bot maze_1_robot_camera.launch.py
I get the error

[gazebo-1] [ERROR] [1659383314.723800169] [gazebo_ros_node]: Found multiple nodes with same name: /camera_controller. This might be due to multiple plugins using the same name. Try changing one of the the plugin names or use a different ROS namespace. This error might also result from a custom plugin inheriting from another gazebo_ros plugin and the custom plugin trying to access the ROS node object hence creating multiple nodes with same name. To solve this try providing the optional node_name argument in gazebo_ros::Node::Get() function.

[ERROR] [gazebo-1]: process has died [pid 24592, exit code 255, cmd 'gazebo --verbose /home/scott/ROS2-Path-Planning-and-Maze-Solving/path_planning_ws/install/maze_bot/share/maze_bot/worlds/maze_1.world -s libgazebo_ros_factory.so'].

[gazebo-1]

and the program stops responding

When trying with ros2 launch maze_bot maze_2_robot_camera.launch.py the program runs ok

Steps to Reproduce

1. Fresh install of ubuntu 22.04
2. installed ros humble and followed setup as per course guide
3. cloned git hub repository and followed steps in guid up to this point with no issues

Expected behavior:
Gazebo will launch with the maze loades

Actual behavior:
Program throws above error then stops

Description

Hi !
I'm in the step of localization (bot_localization.py).
I create a simple world (4 walls only) and try to extract the backgroung model ,but comes with this error.

The camera is working but the variable "min_cntr_idx" is -1, seems that the function "ret_smallest_obj" does not work...
How can I deal with this error?
Should I move the camera or modify the functions in utilities.py?
Thank you for help!

Steps to Reproduce

1. Launch the word(maze)
2. Run "maze_solver.py"

Expected behavior:
The frame "frame_car_remvd" should be showed.

Actual behavior:
Comes in error:
UnboundLocalError: local variable 'frame_car_remvd' referenced before assignment

Description

I follow the video instructions and setup everything according to it. I could not run maze_2_robot_camera.launch.py from beginning from lecture 1, part 4. Run Complete Project without docker.

Steps to Reproduce

1. colcon build
   getting just this: Starting >>> maze_bot
   Finished <<< maze_bot [4.31s]

Summary: 1 package finished [10.7s]

2. source install/setup.bash
   3.ros2 launch maze_bot maze_2_robot_camera.launch.py

Expected behavior:
I expect to get reaction as what happened in the video. After running 'ros2 launch maze_bot maze_2_robot_camera.launch.py', Gazebo should have opened.

Actual behavior:
I am getting this information/messages:
