See what I got all on ROBOTICS...



A robot is a mechanical or virtual, artificial agent. It is usually an electromechanical system, which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical and virtual software agents, but the latter are usually referred to as bots to differentiate.
While there is still discussion about which machines qualify as robots, a typical robot will have several, though not necessarily all of the following properties:
Is not 'natural' i.e. has been artificially created.
Can sense its environment.
Can manipulate things in its environment.
Has some degree of intelligence, or ability to make choices based on the environment, or automatic control / preprogrammed sequence.
Is programmable.
Can move with one or more axes of rotation or translation.
Can make dexterous coordinated movements.
Appears to have intent or agency (reification, anthropomorphisation or Pathetic fallacy).


Defining characteristics
The last property (above), the appearance of agency, is important when people are considering whether to call a machine a robot. In general, the more a machine has the appearance of agency, the more it is considered a robot.

KITT is mentally anthropomorphic
Mental agencyFor robotic engineers, the physical appearance of a machine is less important than the way its actions are controlled. The more the control system seems to have agency of its own, the more likely the machine is to be called a robot. An important feature of agency is the ability to make choices. So the more a machine could feasibly choose to do something different, the more agency it has. For example:
a clockwork car is never considered a robot
a remotely operated vehicle is sometimes considered a robot (or telerobot).
a car with an onboard computer, like Bigtrak, which could drive in a programmable sequence might be called a robot.
a self-controlled car, like the 1990s driverless cars of Ernst Dickmanns, or the entries to the DARPA Grand Challenge, which could sense its environment, and make driving decisions based on this information would quite likely be called robot.
a sentient car, like the fictional KITT, which can take decisions, navigate freely and converse fluently with a human, is usually considered a robot.
