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.
