This snake can save people stuck under rubbles by sneaking in. Its infrared sensor detect body heat and transfer the information to the computer through an Arduino card. The snakes describe a sinusoid movement, we configured the robot via an equation of a harmonic movement configuring each parameter to bring the snake to opperate a movement alike. The snake contains six servo motors each of them configured to turn in harmony with the others. All the extra components like the battery, the cable, etc. are at the rear of the snake. Our project has a Humanitarian objective. We wanted to rescue people as fast as possible, the time being critical. This project is an innovation in the field of rescuing people involving mathematical and physical approach. A huge gain of time for rescuers.
