Some of their talent date back to sheep shearing robots in the early 1980s.
In the same geographic region (W.Australia) there are related automata projects such as self recharging drone clouds about tractors, agri-bots (visual identification + weed spraying), integrated geophysical air survey, etc.
I was somewhat curious as to your awareness of all this (eg: Rio's plans for a full automated "bottom up" $64 billion copper mine in the US (should it go ahead)).
Also, while we're here, do you have any in house mining | industry experience driving tractors, dump trucks, ship loading, etc. yourselves?
