                         ROBOT GRIPPER
                            A robot gripper is a specialized end effector that can take either of two general
                            forms: handlike, and non-handlike. These two main schemes arise from
                            different engineering philosophies.
                              Some researchers say that the human hand is an advanced device,having
                            evolved by natural selection. Therefore, they say, robotics engineers should
                            imitate human hands when designing and building robot grippers. Other
                            roboticists argue that specialized grippers should be used, because robots
                            ordinarily must do only a few specific tasks. Human hands are used for
                            many things, but such versatility might be unnecessary, and even detri-
                            mental, in a robot made for a single task.

                         ROBOTIC SHIP
                            A modern passenger jet can be,and to a large extent is,flown by a computer.
                            It has been said that such an aircraft could take off from New York, fly to
                            Sydney, and land without a single human on board. Such an aircraft is,
                            in effect, a robot. In a similar way, ocean-going vessels can be controlled
                            by computers.
