Snake arm robots are a remarkable example of biomimicry in robotic manipulators, with the flexibility and versatility as an elephant trunk. By replacing conventional rigid body robot arms with snake arm robots, we can significantly increase the working envelope of the mobile robot. The unique design of these robots, featuring a rigid backbone and connecting disks controlled by treads, allows for exceptional flexibility while reducing the overall weight of the robot. This characteristic makes snake arm robots ideal for reaching tight spaces that would otherwise be inaccessible with traditional robots.

These innovative robots find extensive applications in various fields, particularly in surgery and rescue operations. Their high flexibility enables precise and intricate movements, making them valuable tools in delicate surgical procedures. Additionally, snake arm robots excel in navigating challenging terrains during rescue missions, where access to confined or complex spaces is crucial.

The functionality of the robot is achieved through a system of controlling treads connected to stepper motors. By adjusting the length of these controlling treads, the robot's movements can be precisely controlled, mimicking the agility and adaptability of a snake. The entire system is efficiently managed and coordinated using an Arduino Uno microcontroller, which is interfaced with a mobile phone via Bluetooth for seamless and convenient control.

The incorporation of snake arm robots into various industries and applications represents a significant leap forward in robotic technology. By emulating nature's ingenious designs, these robots offer enhanced performance, increased maneuverability, and unparalleled access to confined spaces, making them invaluable assets in advancing the fields of surgery, rescue operations, and beyond.
