Conclusion:
Robots have wide-ranging commercial implications. Robots are used extensively in the automotive industry, primarily for welding, painting and material handling applications. The electronics, aerospace, metalworking and consumer goods industries are also major robot users. Integrated factory automation systems, to which robot technology is key, affect nearly all types of manufacturing. In the near future, productivity and competitiveness in these industries will depend in large part on flexible automation through robotics.

Introduction:
From a performance standpoint, the perceived benefits of a robotic security or surveillance capability are numerous and well documented:
1) humans are removed from direct exposure to potentially dangerous situations;
2) robotic systems can perform many security and surveillance functions more effectively than humans;
3) robots don’t get bored and thereby inattentive during long hours of surveillance; and
4) robots don't participate in "inside jobs. "
In addition, the robotic site-security application has certain advantages relative to more ambitious battlefield scenarios:
1) the operating environment is known in advance and can to some degree be tailored to support robotic installation;
2) experience-based costs of conventional security measures and documented inventory shrinkage together provide a sound and credible basis for cost/benefit tradeoffs. An industrial robot is officially defined by as an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes. The field of robotics may be more practically defined as the study, design and use of robot systems for manufacturing. The most commonly used robot configurations are articulated robots, scara robots and gantry robots (aka cartesian coordinate robots, or x-y-z robots). In the context of general robotics, most types of robots would fall into the category of robot arms (inherent in the use of the word manipulator in the above-mentioned iso standard).
Robots exhibit varying degrees of autonomy:
• some robots are programmed to faithfully carry out specific actions over and over again (repetitive actions) without variation and with a high degree of accuracy. These actions are determined by programmed routines that specify the direction, acceleration, velocity, deceleration, and distance of a series of coordinated motions.
• other robots are much more flexible as to the orientation of the object on which they are operating or even the task that has to be performed on the object itself, which the robot may even need to identify. For example, for more precise guidance, robots often contain machine vision sub-systems acting as their "eyes", linked to powerful computers or controllers. Artificial intelligence, or what passes for it, is becoming an increasingly important factor in the modern industrial robot Dtmf Dual-tone multi-frequency (dtmf) signaling is used for telephone signaling over the line in the voice-frequency band to the call switching center. The version of dtmf used for telephone tone dialing is known by the trademarked term touch-tone (canceled march 13, 1984), and is standardized by itu-t recommendation q. 23. Other multi-frequency systems are used for signaling internal to the telephone network. As a method of in-band signaling, dtmf tones were also used by cable television broadcasters to indicate the start and stop times of local commercial insertion points during station breaks for the benefit of cable companies. Until better out-of-band signaling equipment was developed in the 1990s, fast, unacknowledged, and loud dtmf tone sequences could be heard during the commercial breaks of cable channels in the united states and elsewhere Block diagram Block diagram: Working: User makes the call to the mobile phone connected to robotic assembly. After receiving the call, when user presses the keys on his mobile phone a tone (dtmf) is generated which is being given to a dtmf converter at the robotic side. The dtmf tone will be having specific meaning depending on key pressed and the program written in the microcontroller at robots side. The mobile based user interface is to easily maneuver the robot. Microcontroller at the robot side is interfaced to four dc motors through relays providing individual control for all the movements. One motor is connected at base for circular movement of complete arm assembly. One motor is connected to provide elbow like movement resembling the human arm movement. One motor will again provide circular movement of the wrist assembly. The fourth motor is to control jaw movements to grip and pick up objects.
