A four-wheeled device, known as Rover, has been tested by a team at Sydney University. It was used to move a herd of cows from a field to a dairy.
Researchers were amazed at how easily cows accepted the presence of the robot.
They were not fazed by it and the herding process was calm and effective, they said.
Because the robot moved in a steady manner it allowed cows to move at their own speed which was important in reducing lameness among cattle, Dr Kendra Kerrisk, dairy researcher and associate professor, told the BBC.
