A robot is a mechanical device for doing work. However, not all
mechanical devices for doing work are robots. Here is my definition
of a robot:
A robot must be mobile. If it doesn't have mobility, it's not
A robot must be able to physically affect it's environment. A device that
merely points a camera and looks around is not a robot.
A robot must operate independently from human control for extended periods.
If it's not autonomous, it's not a robot.
A robot is an artifact. Humans themselves are therefore not
robots. This definition will need to be modified when robots evolve to
the point that they can reproduce themselves.
All that being said, the science of robotics is concerned with the various aspects
described above, so most of the research topics in this area are not concerned
with complete robotic systems. For example, a researcher working in manipulation
and grasping is still doing "robotics."
