Humanoid robots are anthropomorphic robots designed to resemble the human body. They typically have a torso, two arms, two legs, and a head. This allows them to interact with human environments and interfaces. The term "robotics" was coined by Isaac Asimov in the 1940s, who also proposed three laws of robotics to ensure robots do not harm humans. Honda developed some of the earliest humanoid robots in the 1990s like the P1 prototype to study bipedal locomotion. Modern humanoids have sensors, effectors, controllers and articulated limbs to mimic human abilities and be deployed for useful tasks. While not as capable as humans, humanoid robot technology continues to advance.
