The robot is your shepherd. In collaboration with cloud robotics firm Rocos, Boston Dynamics demonstrates how their robot dog Spot can herd sheep and handle other farming tasks. From the video description:
The use of autonomous robots in agriculture is increasing the efficiency of food production. Robots, like Spot from Boston Dynamics, increase accuracy in yield estimates, relieve the strain of worker shortages, and create precision in farming.
