British Filmmaker John Downer has created artificial monkeys, wolves, hippos, turtles, alligators, etc., to observe appropriate wildlife and obtain spectacular images. His well-known robots are very intricately designed and resemble the animals they mimic in almost every detail. It is not necessary to resort to such technically elaborate and artistically demanding means for all species. USA Today reports in a recent article about a robot called ECHO. „ECHO is a remote-controlled ground robot that silently spies on the emperor penguin colony in Atka Bay. The robot is being monitored by the Single Penguin Observation and Tracking observatory. Both the SPOT observatory, which is also remote-operated through a satellite link, and the ECHO robot capture photographs and videos of animal population in the Arctic.“ (USA Today, May 6, 2022) ECHO does not resemble a penguin in any way. It is a yellow vehicle with four thick wheels. But as a video shows, the animals seem to have gotten used to it. It comes very close to them without scaring them. Wildlife monitoring using robots is becoming increasingly important, and obviously very different types are being considered.
