How to make changes to robot.py module active?

[geoc1234]

I have a Nano 4gb b0. My robot base uses an arduino, which listens for cmd_vel_msgs over ROS. i need to modify the Robot class in the jetbot container so that it publishes ROS messages, but i don't know how to make any of the edits i make to robot.py take effect.

am i supposed to execute /docker/build.sh after making changes?

Hey @geoc1234,

Thanks for reaching out!

I think the following commands should work

cd docker
./disable.sh
./configure.sh
./build.sh
./enable.sh

I'd recommend modifying JETBOT_VERSION in docker/configure.sh to something else like JETBOT_VERSION=ros_motors so you can keep / use the old container if needed.

Please let me know if this helps or you have any questions.

Best,
John

@jaybdub (John), thank you!

Your suggestion worked. Although, because I modified the docker file for the base to include instructions for building ROS noetic, the build.sh script takes a long time to run because it rebuilds ROS. Maybe I have something configured incorrectly or am not using docker correctly? I'm not a programmer, but isn't python an interpretive language. If so, why wouldn't changes to the source *.py module become active without a build?

Again, thanks so much for your help. How do I send you a coffee?
