Robot Mechanisms and Mechanical Devices Illustrated - Profe Saul

INTRODUCTION
A modern motion control system typically consists of a motion controller,
a motor drive or amplifier, an electric motor, and feedback sensors.
The system might also contain other components such as one or
more belt-, ballscrew-, or leadscrew-driven linear guides or axis stages.
A motion controller today can be a standalone programmable controller,
a personal computer containing a motion control card, or a programmable
logic controller (PLC).
All of the components of a motion control system must work together
seamlessly to perform their assigned functions. Their selection must be
based on both engineering and economic considerations. Figure 1-1
illustrates a typical multiaxis X-Y-Z motion platform that includes the
three linear axes required to move a load, tool, or end effector precisely
through three degrees of freedom. With additional mechanical or electro-
Figure 1-1 This multiaxis X-Y-Z
motion platform is an example of
a motion control system.
