The utilization of Robotics in military is well shown by US army. Osama and other terrorists were tracked by these military robots. They are robust, they are obedient, they are daring, they don't have fear of death, and most important they have proved themselves in Iraq and Afghanistan. Now, terrorists are terrified by drone attacks. The utilization of robotics technology in military led to a new field in robotics i.e. Military Robotics. Military robotics isn't about creating an army of humanoids but utilization of robotics technology for fighting terror and defending the nation. Thus, military robots need not be humanoids or they not necessarily need to carry weapons, they are just those robots that can help the armed forces. The opportunities offered by these technologies are boundless. Apart from army research centers there are many private firms also which provide military robots for defense forces like Foster Miller,21st Century Robotics, EOD Performance, Northrop Grumman, General Atomics etc. They have created many job opportunities and are developing this sector. It is expected that its market will extend up to $9.8 billion by 2016.
History The vision of robot army isn't a present day concept. The introduction of military robots is dated back from 1898 by the introduction of radio boats by Nicola Tesla. It was visualized by many visionaries in the last century. They were used by Germans and Russians in Second World War. Russians used Teletanks and Goliath were used by Germans. The Teletanks were equipped with DT machine guns, flamethrowers and smoke container to provide a smokescreen. The use of Goliath which is a mobile landmine in World War II by the Third Reich's forces also marked as a turning point in the history of military robots. And today the development in this technology is well demonstrated by military robots in Afghanistan and Iraq. At present the most commonly used military robot is the unmanned aerial vehicle IAI Pioneer and RQ-1 Predator.
One threatening question must be arising, as in every science fiction movie, it is shown that robots have gone crazy and started hunting us, will they go crazy in real world also? Actually, at present it is almost impossible. The developers have very well taken care of this aspect. Most of the military robots are remotely controlled by a human. And if someone has gone crazy then there is a reset button which clear there memory and they again come back to normal state. But with the development in artificial intelligence and military robots, there should be greater attention to implicate their ability to make autonomous decision.
