Although robots will one day become autonomous, today they still rely on humans for help. The Mars rover had some autonomy, but it really just executed the intent of the operator back on Earth.
Robots don’t always need to be independent. Some are becoming artificial extensions of the human form, such as suits or exoskeletons that strengthen arms and legs.
