Robot to Herd Cows

Researchers at the University of Sydney tested the device, known as Rover, to herd cows. It was used to move a herd of cows from a field to a dairy. 

Early results showed that cattle have adapted to it well and farmers are keen on the idea, researchers said. 

Since 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 at the university, told the BBC. 

Robots are already used in the milking process but the team wanted to see if they could be used in other areas of dairy farming.
