With the aim of making human life and work simple robotics and automation has played a key important role. This project deals with the study of robotics. This project focuses on building a spying robot which have similar characteristics as biological snake . it has mechanical part which is constructed by using aluminum metal. for movements we use servomotors which can be rotated at a particular angle when they are programmed with PWM coding technique. the snake is attached with wireless camera which sends signals to the base station using RF transmitter and receiver. this robot also has the ability to move autonomously and it avoids obstacles as it moves. a snake is ideal for travelling through rough areas,exploration,remote sensing in hostile areas,landmine detection resulting into saving human life in war fields. https://www.ijiert.org/paper-details?paper_id=140900
