Hello, this is Janna and Tenny! Here are the changes we made for the multi-robot setup. In our version:

  • Changes in hello_helpers/src/hello_helpers/hello_misc.py are made in stretch_ros on the local computer, and
  • Changes in stretch_core/launch/stretch_driver.launch, stretch_core/nodes/stretch_driver and stretch_core/nodes/joint_trajectory_server.py are made in stretch_ros on the robots

We combined these changes in the same stretch_ros package, so the users need to change stretch_ros on the computer and robot separately as mentioned above. Thank you!

Hi @tenny-yinyijun, thank you for opening this pull request! I think this will be very helpful to those looking to run multi-robot experiments. I've left some feedback below. Let me know if you have any questions about it. If it would help to go through it on a video call, I'd be happy to meet with you.

Instead of remapping these topics in this launch file, we'll move the remapping inside the stretch_driver node. We'll delve into this in the next revision.
