In the past few years, we have covered plenty of robotic snakes capable of conducting inspection & search/rescue missions. If you love building your own robots, you can use this guide by Will Donaldson to make your own robot snake. The guide shows you how to make a single axis and double axis snake.
You are going to need 10 MG996R servos, 1.75mm 3D printing filament, Arduino Nano, and a few other simple parts to complete it.
