Diffbot launch not working on humble

[Pkay14]

Get an error saying that "package 'diffbot_description' not found.

The process of ros2_control_node dies, I am using rpi4, I am guessing it is a problem with gazebo maybe?

Hi, the diffbot_description package is contained in ros2_control_demos. Please refer to DiffBot_HIL_Demo. Our HIL demos intend to make minimal modifications based on the official demos to illustrate which configurations are necessary.

Thank you!

Hi sorry to necro the thread, I have tried following the steps for DiffBot HIL Demo but it doesn't seem to be fetching the diffbot_description despite it being in ros2_control_demo_description.

Any suggestion / help would be greatly appreciated :pray:
