I'm using a Neural Network NN to control a UR5 robot arm. I'm struggling to understand how to exchange information between my ROS network and my neural network. Suppose I'm using ur_modern_driver to read joint_states from the robot, how do I export that data so my NN can use it as an input? Likewise, how do I get a ros node to subscribe to data from the output of my NN which will be the 6d joint commands that need to be plugged into ur_modern_driver/urscript?

I suspect I will need to write my own pubsub node which will interface between ur_modern_driver and my NN but I just can't tell what I should tell the node to pub or sub to. How can a node read/write from/to an external source such as a python script that's being executed, especially when that source is constantly changing? Do I need to edit my script to write the NN output to a specific location, maybe a com port? Can a ros node then listen to that port for incoming data? and vice-versa, for writing to the NN's input?

FYI, I'm not experienced with writing my own ROS nodes or even programming so please be simple. Many thanks.

ROS won't eat unless there's source on everything!

rllab used to have ros utils but these have been removed in the newer 'Garage' version. Also, I could never get the orig

My NN is part of Garage/rllab from Berkeley and has its own deps. if I were to try and recreate it inside ros I know it

I am attempting to control a UR5 robot arm using a neural network controller. With the minimum amount of reconfiguring, to which topic should the joint commands from the neural network be published? The network output will be a tuple of joint movements of +/- 1 degree. How could I test such a publication message using the command line? This is using ROS Kinetic. Thanks, Dom

Ok, will do. Thank you for your help.

If I echo the joint_delta_jog_cmds topic I get an output of: header: seq: 1 stamp: secs: 1550500372 nsecs

Hi gvdhoorn, Thanks for your answer. I have managed to get jog_arm to start publishing to /move_group. I have worked out
