The first, more developed one looked like a fish. That's why it was named - The Fish. The most difficult was the mechanism for the two pairs of eyes, but at that moment everything seemed difficult. Due to a quite logical placement of folds and wrinkles on the face of the plastic sculpture, the mimics left no questions. Each servo drove its own area of skin, and together they were grouped for more complex movement.
Initially, The Fish was made to be controlled by a cable control system, which turned out to be a really bad idea. The tense cables did not give enough reaction speed, and it took a long time to get used to the control panel, as it was constantly changing during experiments.
