I found that Processing has a library for talking to MQTT so …
Will make sense when I get the 360 degree obstacle thingy going as I should be able to send “left a bit” … “righ a bit” messages to the MQTT server etc.
MQTT has much the same topic based thingy as ROS yes? Well, sort off. But golly, to be free of ROS, only in as far as you can work off the IOT as well – and there is likely a ROS-MQTT bridge in any event.
Better yet, it works on Processing for Android! Whooo hooo!
Now, I am in comms with the author of BOOFCV as we type here to sort out why the BOOFCV examples are not compiling for Android Mode. Hmmm.
