in modern day disaster recovery mission has become one of the top priorities in any natural disaster management regime. Smart autonomous robots may play a significant role in such missions, including search for life under earth quake hit rubbles, Tsunami hit islands, de-mining in war affected areas and many other such situations. This paper presents a way to build a low cost rescuing 4-legged bot prototype based on Arduino with multiple features like obstacle avoidance , wireless communication as well as sending the pictures of the area using on board wireless camera. The bot can also fly using heli rotors and can be controlled wirelessly by 4 channel transmitter. In others words we can say that it can walk, it can climb on sloppy surface and it can fly also when needed. This 4-legged-bot is built on an ATmega8 microcontroller which has been programmed using Arduino. This paper also describes the method of terrain negotiation navigation in a hazardous field.
