Chapter 1 - Introduction
1.1 A PERSONAL VIEW
Although many writers are happy to put a date on the day a Japanese (or was
it a Finn?) coined this rather ungainly word, mechatronics has been around
in spirit for many decades.
My first brush with industry involved designing autopilots. The computers
on which they were based used analog magnetic amplifiers—and later
transistors—rather than the digital microcomputer we would expect today.
Nevertheless, how can we describe as anything but a robot a machine that
trundles through the sky, obeying commands computed from a multitude of
sensor signals that enable it to make a perfect automatic landing?
By the mid-1960s, some computers had started to shrink. While the Atlas
was fed a succession of jobs by an army of operators, an IBM1130, built into
a desklike console, allowed real time interaction by the user. Soon we were
able to buy “budget” single-board computers for a thousand British pounds.
Although these had a mere 16 kilobytes (kbytes) of memory, their potential
for mechatronics was immense.
One of my Cambridge researchers took on the task of revolutionizing the
phototypesetter. The current state of the art was to spin a disk of letter
images, triggering a flash to expose each letter onto photographic film. This
was certainly “mechatronic” to an extent, requiring the precision positioning
and timing under electronic control, but the new approach distilled the essence
of mechatronics.
