Robot Cowboys Monitor And Manage Animals On Giant Australian Farms

Farmers, put your feet up. Autonomous robots are already being used to inspect crops, count yields and dig up weeds– now they are shepherds too.

Sheep and cattle farms in the Australian outback are vast as well as remote. For example, the country’s most isolated cattle station, Suplejack Downs in the Northern Territory, extends across 4000 square kilometres and takes 13 hours to reach by car from the nearest major town, Alice Springs.

The livestock on these far-flung farms are monitored infrequently – sometimes only once or twice a year – meaning they often fall ill or get into trouble without anyone knowing.

But robots are coming to the rescue. A two-year trial, which starts next month, will train a “farmbot” to herd livestock, keep an eye on their health, and check they have enough pasture to graze on.

“You’ve also got colour, texture and shape sensors looking down at the ground to check pasture quality,” he says.

During the trial, Sukkarieh and his colleagues will fine-tune the robot’s software to make it adept at spotting ailing livestock, and to ensure that it can safely navigate around trees and over mud, swamps and hills.

“We want to improve the quality of animal health and make it easier for farmers to maintain large landscapes where animals roam free,” says Sukkarieh. Another goal is to reduce the reliance on feedlots, which keep livestock in closely confined areas that are easy to oversee.

Every advance in robot technology stirs up fears about human redundancy, says Sukkarieh, but farm labouring vacancies are increasingly difficult to fill and can be replaced by jobs in robot maintenance. “It’s farmers who are driving this because labour is in short supply and they are looking for technological assistance,” he says.
