Introduction: The Rise of Humanoid Robotics
Humanoid robots—machines designed with a bipedal or human-like form—are transitioning from research prototypes and demonstration platforms into practical industrial, logistics, and service applications. Unlike traditional robotic arms or wheeled mobile robots, humanoid robots combine mobility, dexterity, perception, and cognitive capabilities, enabling them to navigate complex, unstructured environments designed for humans.
The increasing capabilities of humanoid robots are driven by advances in actuation, sensors, artificial intelligence, and human-robot collaboration frameworks. As industries and service sectors seek flexibility, efficiency, and adaptability, humanoid robots are positioned to fill roles that previously required human labor—particularly in environments unsuitable for conventional automation.
