The strategy of this project is to decrease the fire accidents as soon as possible after the occurrence by moving towards the fire and pump out water around it to put down the fire.The robot is controlled by using the application.It was very useful in large industries and factories.We detect the direction of the fire we can use the motors to move near the fire by driving our motors. When near a fire we have to put it out using water. Using a small container we can carry water, a 5V pump is also placed in the container and the whole container is placed on top of a servo motor so that we can control the direction in which the water has to be sprayed.

Reversible data hiding is a type of data hiding techniques whereby the host image can be recovered exactly.Data hiding technique is used to put a secure data in a host media (like images) with small deterioration in host and the means to extract the secure data afterwards. For example, steganography can be named. Steganography is one such pro-security innovation in which secret data is embedded in a cover. The rapidly proliferated information and evolution of digital technologies by Information hiding in multimedia data has improved the ease of access to digital information enabling reliable, faster and efficient storage, transfer and processing of digital data. In Reversible Image Transformation encrypted image can be reversed to the original cover media exactly. Being lossless makes this technique suitable for medical and military applications. First, secret image and original images are filtered to eliminate the noise from them. Then secret image is embedded in the cover image which is then encrypted to be sent on network. At receiver side, decryption is done first. From that image secret image is extracted and original image is recovered.
