ROS2 Basics in 5 Days: Course Project : ros1 bridge error

[BushraAlsh]

Hello !
I’m doing the project for ros2 basic. I’ve reached the part with the services.
It’s working in the simulation. When I try it on the real robot.

I used the code provided in the notebook :
“”
source ~/catkin_ws/devel/setup.bash

roslaunch load_params load_params.launch

source /opt/ros/foxy/setup.bash

ros2 run ros1_bridge parameter_bridge
“”
But I get the following error. Also, in this case, if I want to build after adding a code, which source should i source, and I will navigate to the ros2_ws when i write colcon build ?

Thanks,

Hi @BushraAlsh, I think you might have an older version for your project, since it is no longer required to run the ros1 bridge. Everything runs in ROS 2.

Here are the latest rosjects:

• If you are doing ROS Basics in 5 Days Python: https://app.theconstruct.ai/l/404c2ba6/
• If you are doing ROS Basics in 5 Days C++: https://app.theconstruct.ai/l/3de839f6/
