How i can acces to the output of the object detection node

hello, The node is working in the robot’s terminal, but the thing is that i want to execute the navigation.launch and stretch_detect_object.launch at the same time, but i i try this the robot can’t move, because only one stretch_driver node could run at an instance and I have to modified the the launch file as you told in other post.
I need to execute both file, due to I am using the robot to looking for a object in a lab base on probabilities.
