VOA科学技术2024--Robot Leads Cattle to Greener Fields

（单词翻译）

Researchers in Australia are using a robot powered by artificial intelligence (AI) to improve the way farmers raise cattle.

The robot has four wheels and is painted red.

Researchers have named the robot cow SwagBot. It can drive by itself and move cows from one field to another based on the condition of the soil and plant life.

Researchers at the University of Sydney in Australia said SwagBot is becoming the world's first "smart cow." They believe it can make cattle farming more efficient and put less pressure on the environment.

Swagbot was first launched in 2016. At that time, it could only move around fields where cattle graze. Over time, scientists have added sensors¹ and AI systems to the robot.

These systems help SwagBot judge the health, type, and thickness of grasses and plants in fields and to observe the health of the cattle.

The robot uses this information to move cattle to the best areas for grazing. The goal is to move cattle to a new grazing area before they have damaged the grass in a particular field. This can prevent damage to the soil. The robot can also send the information back to farmers.

Salah Sukkarieh is a professor of robotics and intelligent systems at the University of Sydney. His team made SwagBot. He said that once cattle feel at ease near the robot, they follow it around.

"You want to move the animals to the right part of the pasture where there is good protein, good carbs," he said. Sukkarieh added that it is important to move the cattle easily and without fences.

Australia is one of the world's biggest exporters of beef. It has around 30 million cattle spread across large areas that are often dry. As a result, some pastures are of low quality and do not have a lot of grass.

Farmers carefully assess how many animals their land can support. However, many farmers have little control over where the animals graze within large areas of land. Overgrazing can lead to poor soil that supports less plant and animal life.

Erin O'Neill is a part-time farmer who watched a recent demonstration² of the robot in a field north of Sydney. She said the robot can help farmers get detailed³ information about the current condition of their fields.

She said the robot can tell farmers "what bits of pasture are most nutritious⁴, particularly if you've got cattle like we do that are pregnant." O'Neill added that pregnant cattle need high-quality pastures to aid them through pregnancy⁵.

SwagBot is still in development. It is part of a growing movement in agriculture towards robotics. Farming experts hope robots can make production more efficient. Robots could also reduce the need for workers in places, like Australia, where finding workers in areas with a low population can be difficult.
