Rambo Tribble writes "The BBC reports on efforts at Sydney University, where researchers have had excellent success herding dairy cows with robots. By designing the robots to move smoothly, they have kept the cows moving without stressing them. From the video, one can see the animals seem not to interpret the machine as any threat. 'The robot could also cut down the number of accidents involving humans on farms. Most dairy farmers in Australia use quad bikes to round up their cattle and they are one of the leading causes of injury. The team hopes that by using the robot to do the job instead, accident rates could fall.'"
