1. The manipulator has a long working time and can continue to operate 24 hours a day, while the human has to have a rest time.                                                                                                                                                                                  2. It can be replaced by manual dangerous operation. In some fields, many processes are very dangerous, and the operation of the stamping manipulator will eliminate the boss's concern.                                                                                    3. Low cost, half a year to pay back the cost, an injection molding manipulator is about 50,000, the number of axis is different, the cost in the early stage will be a lot of money, but according to the time and month, it will be equivalent to the employee's salary for half a year.                                                                                                                                            4. No pay, high efficiency, of course, robot is not paid, and drilling efficiency is very high, compared with the error rate of human is much lower.                                                                                                                                                              5. Reduce workers' dependence on manual skills.In China, the proportion of general labor is very high, the dependence of workers' manual technology is also very large, the society needs to progress, it is inevitable that the manufacturing industry will continue to technology, efficiency, manipulator to replace manual, will also reduce the dependence of workers on manual technology.
