In my opinion, you get some advantage it you have a robot security guard to safety. the first advantage is get through security because the robot is able to enforce the order and immediately command and can also execute command successful. The second advantage is that the robot can work fully effective monitoring at all times. In addition, auto stocks have not be able to sneak a NAP at work and not be able to sneak away to do other things besides work. In conclusion, security guard to build trust in their own security and to make it feel comfortable.
