Picking a cauliflower seems a very easy task, at least to anyone who has only ever encountered the brassica on a plate accompanied by meat and other vegetables.
But knowing the right moment to pick a cauliflower is tricky. Harvest it too soon or too late and supermarket chains might reject the whole crop for being too big or small.
There are also problems of finding labour willing to do the picking.
"It's a horrible job and there's not enough people doing it," said Dr Richard Dudley from the National Physical Laboratory (NPL), which is working on a robot to replace the human harvesters.
Human-based methods of picking cauliflowers involve about 15 people walking in front of a harvester checking cauliflowers to see if they are the right size, cutting them and then placing them in a hopper. All in a few seconds.
No wonder, then, that mistakes are made and the system is not very efficient.
"At the moment they do one pass and anything that's left is usually left to rot away," said Dr Dudley.
Dr Dudley and colleagues at NPL along with agricultural firm Vegetable Harvesting Systems (VHS) are working on robots that are as fast as humans at working out if a cauliflower is ready to be picked.
SourceDo you own a John Deere 318 and looking for information or help? You can still find valuable information online about the 318 that will help you with answers to your questions, whether it is on a particular part that you need, or just general information on a certain model. This article gives a description, specifications, and a list of attachments for the 318 lawn mower.
The John Deere 318 was in production from 1983 to 1992. They were manufactured in Horicon, Wisconsin, a small town in Dodge County. It was manufactured, of course, under the John Deere name and labeled as a garden tractor. There were three models that were in this group: a smaller version, the John Deere 316, John Deere 317, and the John Deere 318.
They were very popular and there are many still around. Many of them have since been fine tuned or adapted with alternate parts to keep them running. Many owners of the original 318 have had problems with the Onan engine and have replaced it, with success, with a different type of engine. This allowed the 318 to continue as a valuable piece of equipment that continues with a good performance record.
