A robot comes to life instantaneously when we hack human instinct and psychology. By building elaborate bio-based skeletons and tuning robotic interactions to biological instincts, we can create surprising and engaging systems that people subconsciously consider "alive." Underscore this with a few psychological elements, and you've got an irresistible, lifelike illusion that enthralls and repulses. Have fun times with biomimicry, and learn to make your own little monsters!
