An anonymous reader writes: 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. 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. Sick and injured animals will be identified using thermal and vision sensors that detect changes in body temperature and walking gait, says Salah Sukkarieh of the University of Sydney, who will carry out the trial on several farms in central New South Wales. The robot, which has not yet been named, is a more sophisticated version of an earlier model, Shrimp, which was designed to herd groups of 20 to 150 dairy cows.
