The control system 40 controls the end effector 52 to pick up or release the cargo, and the control system 40 also controls the robot arm 51 to move the end effector 52 to Carrying goods. For example, the end effector 52 is a suction cup device that adsorbs or releases cargo by controlling air pressure. Further, the air pressure sensor 53 is disposed on the end effector 52, and when the industrial robot 50 performs picking up the goods, the end effector 52 is moved to the picking position of the goods, and is closely attached to the picking position of the goods, when the air pressure sensor 53 detects When the pressure value reaches a certain threshold, the control system 40 controls the end effector 52 to perform the picking action. If the pressure value detected by the air pressure sensor 53 does not change thereafter, the control system 40 determines that the end effector 52 has not picked up the cargo, if the air pressure sensor 53 detects another pressure value, and the control system 40 determines that the end effector 52 picks up the cargo, thereby controlling the industrial robot 50 to perform the handling action. When the control system 40 determines that the end effector 52 has not picked up the cargo, the control system 40 further determines that the cargo posture within the cache bay 10 is in a non-pickup state, thereby controlling the dialing device 20 to adjust the attitude of the cargo within the cache bay 10. When the industrial robot 50 is ready to release the cargo, the air pressure sensor 53 detects that the pressure value received by the end effector 52 reaches another value, the industrial robot 50 performs the release action; of course, the industrial robot 50 performs the release action and may also be independent of the air pressure sensor 53. Whether or not the picking or releasing action is performed is determined, for example, by the visual recognition system 30. Further, the control system 40 also dynamically adjusts the suction force or the gripping force of the end effector 52 on the cargo according to the cargo information acquired by the scanning device 32, such as the weight of the cargo, thereby saving energy consumption and overweight cargo can still be Pick up.
