英语六级阅读真题预测：农业机器人
Questions 46 to 50 are based on the followingpassage.
Perhaps it is time for farmers to put their feet upnow that robots are used to inspect crops, dig upweeds, and even have become shepherds, too. Commercial growing fields are astronomically hugeand take thousands of man-hours to operate. One prime example is one of Australia's mostisolated cattle stations, Suplejack Downs in the Northern Territory, extending across 4,000 square kilometers, taking over 13 hours to reach by car from the nearest major town—AliceSprings.
The extreme isolation of these massive farms leaves them often unattended, and monitoredonly once or twice a year, which means if the livestock falls ill or requires assistance, it canbe a long time for farmers to discover.
However, robots are coming to the rescue.
Robots are currently under a two-year trial in Wales which will train 'farmbots' to herd, monitor the health of livestock, and make sure there is enough pasture for them to graze on. The robots are equipped with many sensors to identify conditions of the environment, cattleand food, using thermal and vision sensors that detect changes in body temperature.
"You've also got color, texture and shape sensors looking down at the ground to checkpasture quality," says Salah Sukkarieh of the University of Sydney, who will carry out trials onseveral farms in central New South Wales.
During the trials, the robot algorithms (算法) and mechanics will be fine-tuned to make itbetter suited to ailing livestock and ensure it safely navigates around potential hazardsincluding trees, mud, swamps, and hills.
"We want to improve the quality of animal health and make it easier for farmers to maintainlarge landscapes where animals roam free," says Sukkarieh.
The robots are not limited to herding and monitoring livestock. They have been created tocount individual fruit, inspect crops, and even pull weeds.
Many robots are equipped with high-tech sensors and complex learning algorithms to avoidinjuring humans as they work side by side. The robots also learn the most efficient and safestpassages, and allow engineers and farmers to analyze and better optimize the attributes andtasks of the robot, as well as provide a live stream giving real-time feedback on exactly what ishappening on the farms.
Of course, some worry lies in replacing agricultural workers. However, it is fanners that arepushing for the advancements due to ever-increasing labor vacancies, making it difficult tomaintain large-scale operations.
The robots have provided major benefits to farmers in various ways, from hunting and pullingweeds to monitoring the condition of every single fruit. Future farms will likely experience agreater deal of autonomy as robots take up more and more farm work efficiently.
