[0002] A robotic arm end effector, also known as an end-effector, is a component mounted on a robotic arm for gripping, handling, and placing items. Its design and function vary widely to adapt to different application scenarios and operational needs. Robotic arm end effectors offer a high degree of automation, effectively improving production efficiency and operational accuracy.
[0003] To further improve the automation level of robotic arm end-effectors, existing technologies include robotic arm end-effectors with detection functions. These end-effectors are equipped with information acquisition modules such as cameras to enable detection capabilities. However, the information acquisition modules of existing robotic arm end-effectors with detection functions are fixed. Because the camera is fixed, it cannot flexibly inspect the workpiece, especially when the workpiece is irregularly shaped. This leads to incomplete detection and prevents preliminary visual inspection before workpiece gripping, unnecessarily increasing the amount of manual work required in subsequent operations.
