How to publish output from Android App to ROS master via USB connection?

Hello, My Android app which is a ROS node, creates JSON files that I need to be publishing to the master. Can I do this without using hotspot? Also, will I be able to customize what I publish to the master from my android app?

Any help or pointer to the latest way of. implementing this, would be sincerely appreciated.

Hi @rosandimages. With ROS Mobile there is way to create your own widgets and layers that can be a combination of others: https://github.com/ROS-Mobile/ROS-Mobile-Android/wiki/How-to-contribute%3F#add-your-own-nodes.

The following Nodes are currently supported by ROS-Mobile:

  • Debug (similar to rostopic echo)
  • Joystick (geometry_msgs/Twist)
  • GridMap (nav_msgs/OccupancyGrid)
  • Camera (sensor_msgs/Image, sensor_msgs/CompressedImage)
  • GPS (sensor_msgs/NavSatFix)
  • Button (std_msgs/Bool)
  • Logger (std_msgs/String)
