Then, the sensor is used to position and sort the wheel to identify its size. Then, the first robot arm moves the wheel to the corresponding size station and drills it through the three-axis drilling component. After drilling, the second robot arm grabs the wheel and transfers it to the outlet roller conveyor for unloading. Attached Figure Description
