Snakebot

A snakebot, also referred to as a snake robot, is a biomorphic robot that resembles a snake. Snakebots have uses similar to those of certain types of soft robots.
Snakebots can vary significantly in size and design. Their small cross-section-to-length ratios allow them to maneuver through tight spaces. Their ability to change shape allows them to traverse varied terrain.
Snake robots are often designed by connecting multiple independent segments, which provides redundancy and enables continued operation even if some parts are damaged. Snakebots have been posited for a range of practical applications.
A snakebot differs from a snake-arm robot in that, snakebots are usually self-contained, whereas snake-arm robots typically have mechanics remote from the arm itself, possibly connected to a larger system.
