This is not the first time humans use robots to spy on wild animals. We've seen robotic cameras used to film lions before (though not as close), as well as penguins, zebras, and bonobos.
Photographers at National Geographic enlisted the assistance of a little tracked camera robot to shoot lions closely and intimately. They had a ground-level robot, basically a mini remote-controlled tank.
According to what the phorographers said, lions are so supremely confident that they could give a damn about this robot. An elephant would stomp it or run away, and all other animals would run away. After only three visits they didn't care about that tank. At first they were cautious. Some of the most cautious ones moved to the back of the family. But after five or six times they were all falling asleep with it.
