This video shows the first steps towards an automatic lameness detection system for dairy cows. Four sensors record 3D data as cattle walk past. A Neural Network has been trained with hand-labelled data to detect hooves. These detections are projected to 3D and tracked to provide four hoof trajectories. Limb motion is an important indicator of lameness, and an example of hoof placement is shown for a healthy and severely lame cow.
The trial aimed to test the response of cows to the presence of a robot, and determine the feasibility of remote or autonomous herding using an unmanned ground vehicle. The cows were calm with the robot in their midst, and were willing to be herded into the dairy at a gentle pace, proving the potential of this technology. The story has captured the public's imagination, with media coverage around the world:Discovery Channel Canada, ABC Rural, BBC News, tested.com, cnet.com, International Business Times, and more.
