MECHANICAL PICKERS
Although harvesting cereal crops such as wheat and barley has long been done by large machines known as combine harvesters, mechanising the picking of fruit crops such as tomatoes or apples has proved more difficult. Farmers have
generally relied on human labour to harvest these, but in wealthy countries it has become increasingly difficult to find pickers willing to work for the wages farmers are able to pay. This is partly because the demand for lab our is seasonal, usually in the autumn, and also because the work is hard and demanding. As a result, in areas such as California part of the fruit harvest is often unpicked and left to There are several obvious reasons why developing mechanical pickers is challenging. Fruit such as grapes or strawberries comes in a variety of shapes and does not always ripen at the same time. Outdoors, the ground conditions
can vary from to muddy, and winds may move branches around. Clearly each crop requires its own solution: machines may be towed through orchards by tractors or move around by themselves using sensors to detect the ripest fruit. This new generation of fruit harvesters is possible due to advances in computing
power and sensing ability. Such devices will inevitably be expensive, but will save farmers from the complexities of managing a labour force. in addition, the more intelligent pickers should be able to develop a database of information on the health of each individual plant, enabling the grower to provide it with fertiliser and water to maintain its maximum productivity.
