Hi Hello Robot team,
I’m setting up my second robot and running into an error that didn’t appear last time (in May).
I’m following these instructions: stretch_ros/install_noetic.md at dev/noetic · hello-robot/stretch_ros · GitHub
When comes the time to run stretch_robot_home.py
after successfully running all previous commands, I get the following error:
