A 6 DOF (Degrees of Freedom) robot refers to a robot that has 6 axes of motion, each axis representing a degree of freedom. This allows the robot to move in multiple directions, including up/down, left/right, forward/backward, as well as pitch, yaw, and roll. These robots are capable of performing complex tasks, such as handling objects, navigating through tight spaces, and even flying. This wide range of motion makes 6 DOF robots suitable for various industries, including manufacturing, aerospace, and medical.
