Humanoid robots, as highly integrated intelligent devices, possess complex and sophisticated structures designed to mimic human appearance and behavior, achieving diverse functions. For the products mentioned above, please click below to learn more about their specifications.
The structure of a humanoid robot can be broadly divided into several core parts: head, torso, upper limbs, lower limbs, and control system.
The head typically includes a vision system (camera), an auditory system (microphone), a speech system (speaker), and an expression simulation mechanism, enabling the robot to perceive its environment, communicate with humans, and express emotions. The vision system captures images through a camera, performs image recognition and processing, providing the robot with visual perception capabilities; the auditory system receives sound signals through a microphone, enabling speech recognition and interaction; the speech system is responsible for converting text information into speech output, enabling voice communication with humans.
The torso is the core supporting structure of the humanoid robot, integrating a power system, computing unit, and various sensors. The power system provides a stable power supply to the robot, ensuring its continuous operation. The computing unit, the robot's "brain," processes data from various sensors, executing complex algorithms and making decisions. Sensors, including accelerometers, gyroscopes, and force sensors, are used to perceive the robot's posture, motion state, and interaction with the environment.
The upper limbs typically include the shoulders, elbows, wrists, and hands. Each joint is equipped with a drive motor and transmission mechanism, enabling the robot to perform various fine movements, such as grasping, carrying, and manipulating tools. The drive motors provide power, and the transmission mechanism transmits power to each joint, achieving flexible motion control.
The lower limbs are crucial for humanoid robots to walk and run, including the hips, knees, ankles, and feet. The design of the lower limbs needs to consider stability, flexibility, and energy efficiency, typically employing biomimetic principles to simulate human walking mechanisms. Through precise joint control and gait planning, the robot can walk stably on various terrains and even perform complex movements such as jumping and rolling.
The control system is the "nerve center" of a humanoid robot, responsible for coordinating the work of various parts and achieving overall motion control and behavioral decision-making. Control systems typically employ a layered architecture, including low-level motion control, mid-level behavior planning, and high-level decision-making. Low-level motion control ensures precise joint control, guaranteeing the robot moves along a pre-set trajectory; mid-level behavior planning plans the robot's behavioral sequence based on task requirements and environmental information; and high-level decision-making makes optimal decisions based on perceived information and task objectives.
Furthermore, the structural composition of humanoid robots involves knowledge and technologies from multiple fields, including materials science, mechanical design, electrical engineering, and computer science. With continuous technological advancements, the structural composition of humanoid robots will become more optimized, their functions more comprehensive, and their application scenarios more extensive.
