CSIRO says unmanned flying robots could soon be used to muster cattle on outback stations.
If cattle follow an Alpha cow, perhaps the flying robot might eventuality be replaced by a helmet.
The helmet would have electrodes to the Alpha's brain, which cause the Alpha to turn left or right. The helmet would also contain a GPS system. The rancher would send the desired latitude and longitudinal coordinates to the helmet, then put down the 'remote', pick up his Fosters, and go back to watching the football game.
