Penguin robot helps researchers get close and personal
Meet penguin-bot. Remote-controlled rovers disguised as penguins could reduce stress to wild animals during behavioural research
中略
When approached by a human, for instance, a penguin’s heart rate increased by an average of 35 beats per minute. When the rover came at it, its heart rate also increased, but only by around 24 beats per minute. In addition, a human caused the target penguin to move much more (average of 43 cm) than the rover (just 8cm). With the robot, the penguins were also much quicker to return to their original physiological state.
人間が接近するとペンギンの心拍数は35に上がる
ロボ接近のときは上がるけれども24
人間は平均43cmで接近するがロボはたったの8cm
ロボ接近時のペンギンはたいへん速く通常モードに戻るのでペンギンにとってストレスが少ない
