Finally, as they relied on mechanical control they were slow and it was difficult to change many channels at a time.

Aside from its mechanical controls, it looked alive and lethal.

Steering and collision are done through direct mechanical control.

It utilizes a direct mechanical control of electric current to the motors.

Many newer aircraft replace these mechanical controls with fly-by-wire systems.

As a result, smaller tips are possible, and better mechanical control of the tip-cantilever is obtained.

The humans had, of course, disabled the key motor-response cells, leaving it under purely mechanical control.

By the 1980s, computers became small and cheap enough to replace mechanical controls in things like washing machines.

Control systems are responsible for activating and monitoring industrial or mechanical controls.
