All CNC robots are comprised of three core systems:
Motion Control System: Achieves spatial trajectory planning through servo motors and multi-axis linkage.
Sensing System: Provides real-time feedback on operating conditions using force and vision sensors.
Execution System: The end effector performs specific actions such as grasping and welding.
Based on structure, they can be categorized as:
Cartesian Coordinate Type: Suitable for linear transport scenarios, such as palletizing robots.
Articulated Type: Highly flexible with a 6-axis design, commonly found in welding robots.
SCARA Type: High-speed horizontal operation, often used in electronic assembly.
Common Misconception: More axes are not always better. A 4-axis robot is often more economical and efficient than a 6-axis robot in planar operations.
