Robotic Farm machinery

Robotic Farm machinery, using GPS and sensing, can handle routine farm jobs such as spraying using a robotic lightweight tractor. Based in Queensland and with help from Queensland University of Technology and The University of Sydney Field Robotics team, this is a low impact, low cost solution for a farm to cut their labour and fuel costs. 

Instead of spending a year building out a special farm robot, they simply equipped a relatively cheap lightweight farm UTV (pictured below) and spent all their time and effort on the robotic control systems (which is where the problem really is, not with the actual machinery).
