Description:-

Now a day’s science and technology is being used in every stage of human lives. Working in certain fields like high voltage transmission lines, mining at deeper level in earth crest, working with explosive material (bomb) etc. and all such dangerous fields where only robots cannot work by their own intelligence effectively. At the same time only human worker also cannot work safely. To overcome such issues it is necessary to have the system which will fulfil both the requirements i.e. human body will guide the task and machine (robotic Shadow) will act accordingly, consequently the risk factor of working in the above mentioned field will automatically decrease without affecting employment of worker. In the present investigation we have designed a prototype of human head which copies our head movements and eye section of it is programmed on ardiuno uno. currently I am working on robotic hand which uses same principle but with some extra features.
