Ian Ingram makes robots that interact with non-human animals. He studies and replicated behavior and communicative patterns. The effects are often stunning.
His Danger, Squirrel Nutkin! from 2009 is telling. Here he has made a robot that uses computer vision to scan for squirrel predators such as hawks, foxes, and human beings. When they approach the robit warns nearby gray squirrels using an amplified version of their own tail-flick alarm signal if it detects them.
