How to monitor variables in actiongraph

[liuxiao916]

Hi,

Is there any method to monitor the variables in actiongraph? For example, in tutorial mport and Drive TurtleBot3.

I want to monitor the output x.

you can always print things out by using a “to string” node and “print text” node. You may need to change the printing node’s output level from “info” to “warning” to see it in the console.
