Hands-On ROS for Robotics Programming

Scenario 1 – travel to a target location

Follow the next procedure to make sure that the training process happens as expected:

1. First, launch the virtual robot model in Gazebo:

T1 $ roslaunch gopigo3_gazebo gopigo3_stage_1.launch

2. Then, you can start the training process. But first, you have to be in the tensorflow virtual environment:

T2 $ conda activate tensorflow

3. Now, start the training:

T2 (tensorflow) $ roslaunch gopigo3_dqn gopigo3_dqn_stage_1.launch

You might receive an error like this one:

inotify_add_watch("/home/user/.config/ibus/bus/59ba2b2ca56a4b45be932f4cbc9c914d-unix-0") failed: "No space left on device"

Don't worry, you can solve it by executing the following command:

T2 $ echo fs.inotify.max_user_watches=65536 | sudo ...
