A farm is a type of factory, and thus has fairly controlled conditions compared to a public thoroughfare.  Any number of solutions could work for a farm that would be untenable for self driving cars, such as marking the expected area with sensors to define the working area, outlining the area on a GPS map, running the equipment over the area one or more times to teach it, etc.  None of these work as a general purpose solution to a self driving car, and they might not even be progenitors to the self driving technology we end up with.&lt;p&gt;A solution to a highly constrained version of a problem may not be applicable to the general purpose problem in any way.&lt;p&gt;Edit: mean to say &amp;quot;may &lt;i&gt;not&lt;/i&gt; be applicable&amp;quot; in last sentence.</text><parent_chain><item><author>da_chicken</author><text>While I certainly agree that self-driving farm equipment is revolutionary, I&amp;#x27;d argue that Google&amp;#x27;s technological advances are in the field of being able to understand how to drive on a road which marked for humans to drive on, and which is simultaneously in use by human drivers as well.&lt;p&gt;I&amp;#x27;m sure that there are problems and issues which arise from navigating a field and manipulating whatever equipment you&amp;#x27;ve got for whatever task you&amp;#x27;re working on that I&amp;#x27;m just not fully appreciating.

The overlap technologies of position fixing and mechanical control have actually been solved for a long time now. The current interest in self-driving vehicles is based on advances in sensors and processing to detect environmental conditions and hazards on roadways and in places where people commonly drive cars.</text><parent_chain><item><author>da_chicken</author><text>While I certainly agree that self-driving farm equipment is revolutionary, I&amp;#x27;d argue that Google&amp;#x27;s technological advances are in the field of being able to understand how to drive on a road which marked for humans to drive on, and which is simultaneously in use by human drivers as well.&lt;p&gt;I&amp;#x27;m sure that there are problems and issues which arise from navigating a field and manipulating whatever equipment you&amp;#x27;ve got for whatever task you&amp;#x27;re working on that I&amp;#x27;m just not fully appreciating.
