Introduction to Robot Joints
Robot joints are crucial components in robotic systems, serving as the “articulations” that enable robots to move, bend, and perform various tasks with flexibility and precision. They mimic the functions of human joints, allowing robots to achieve a wide range of motion, such as rotation, flexion, and extension. Robot joints can be classified into different types, including rotary joints, linear joints, and spherical joints, each designed to meet specific application requirements. These joints are typically equipped with actuators, sensors, and control systems to ensure accurate and efficient movement. The quality and performance of robot joints directly affect the overall performance and reliability of robots, making them an essential part of the robotics industry. Robot Joints
