The Pleo Dinosaur - a Ugobe life form also has over 100 custom-designed gears, and 14 motors for highly-articulated movement. Each motor has a force feedback sensor that makes them sensitive to forceful grabs at the dinosaur's legs, neck, tail and torso, causing him to shut down during trauma to avoid internal damage. Pleo will actually react to being hurt, perhaps exhibiting a limp, and can recover over time depending on the level of nurturing you exhibit.
