A robot that can walk and climb stairs

A robot which works on its own

Explanation:

An autonomous robot is defined by its ability to perceive its environment and make independent decisions without direct human intervention. Unlike manually controlled machines, it utilizes onboard sensors and artificial intelligence algorithms to navigate obstacles and execute tasks on its own. This self-sufficiency allows it to operate continuously in dynamic settings, adapting to changes without requiring constant external commands. Therefore, the defining characteristic is its capacity to work independently, which directly aligns with the concept of operating on its own. This fundamental trait distinguishes it from robots that rely entirely on human operators for every action.
