Last weeks post came to you live from the tractor, which I think just goes to show how far technology has come to allow me to write a post and publish it on the Internet with pictures all while sitting in the seat of a working tractor in the field. While that shows the power of the smart phone, how was I keeping the rows straight? With most of my attention focused on writing the post the rows must be wonky, but they weren’t, why?
Well firstly I didn’t put the rows in I was on the roller so the rows were already there, secondly I wasn’t driving. So who was driving? Well the tractor was, via the GPS. During normal work in the field the tractor steers itself using the GPS system, multiple satellites work in conjunction with a ground station which has a fixed location to work out the exact location of the tractor in the field and where it should be in order to keep a straight line. The GPS computer then tells the tractors steering system which way to turn and by how much so it can keep a straight line or at least with in two centimetres of it which is more accurate than any operator can drive. How ever a operator is still needed to turn the tractor around at the end of the row as well as monitor temperatures, pressures, levels and the such. So where to from here?
Well in an exciting development coming out the USA we may soon have fully automated tractors that not only keep straight but turn around as well thanks to the development of the Spirit Autonomous Tractor, while it may look like a German WWI tank minus the guns it is jammed packed full of the latest technology and doesn’t even have a cab or need operator. This diesel-electric tractor is fully autonomous with only one controller needed to control up to 16 tractors with in a 40km radius, you can even have multiple tractors working the same field. While these machines are not in the production stage yet there are working prototypes. While this technology is promising and shows great potential I do have some questions about it, how well can it dodge an obstacle like a tree or power pole with the twelve row rig it could be potentially taking to the field? And how well can the controller identify a problem such as a broken pin on the rig or a the rig clogging up with trash from his control room? I guess only time will tell and I’ll be very excited to see a working model in Australia hopefully very soon.
