Iván Hernández Dalas: Unusual robotic animals can prove their utility
Korean researchers have developed a beetle-like soft robot. Source: KAIST When we hear the word “robot,” we still conjure up images of mechanical figures from old science fiction films. However, reality has long since evolved: We’re surrounded by smart vacuum cleaners, voice assistants, and even four-legged machines that mimic dogs. But what are these robotic animals? They’re not just battery-powered toys. They’re complex electronic devices, infused with elements of artificial intelligence, that replicate the appearance and behavior of real or imaginary creatures. These devices contain sensors , speakers, motors , and processor modules that analyze external signals. They’re controlled via mobile apps. Digital pets can make distinctive sounds, respond to signs of affection, answer to their names, and display a range of emotions—from delight to fear, from satisfaction to fatigue. Manufacturers employ a variety of engineering approaches when creatin...
