How Robots Work
The inspiration for the design of a robot manipulator is the human arm, but with some differences. For example, a robot arm can extend by telescoping—that is, by sliding cylindrical sections one over another to lengthen the arm. Robot arms also can be constructed so that they bend like an elephant trunk. Grippers, or end effectors, are designed to mimic the function and structure of the human hand. Many robots are equipped with special purpose grippers to grasp particular devices such as a rack of test tubes or an arc-welder.

How Supercomputers Work

How Supercomputers Work

 The two major components of a supercomputer are the same as any other computer—a central processing unit (CPU) where instructions are carried out, and the memory in which data and instructions are stored. The CPU in a supercomputer is similar in function to a standard personal computer (PC) CPU, but it usually has a different type of transistor technology that minimizes transistor switching time. Switching time is the length of time that it takes for a transistor in the CPU to open or close, which corresponds to a piece of data moving or changing value in the computer. This time is extremely important in
