RQT is a GUI interface that lets you work with plugins and visualization tools for robotics

sudo apt install ~nros-humble-rqt*    to install the rqt packages that are needed
rqt                                   to open the rqt node

Notes: rqt, making service calls from the Service Caller, and the /spawn and set_pen task.

Service calls

The options for service calls is in:
