The robotic system has three basic
components : the manipulator , the controller , and the power source
Manipulator
The manipulator , which does the physical work of the robotic system ,
consists of two sections : the mechanical section and the attached appendage
.
The manipulator also has a base to
which the appendages are attached .
The
base of the manipulator is usually fixed to the floor of the work area .
Sometimes , though , the base may be movable . In this case , Cnc machining the base is
attached to either a rail or a track , allowing the manipulator to be moved
from one location to another .
As
mentioned previously , the appendage extends from the base of the robot . The
appendage is the arm of the robot . It can be either a straight , movable arm
or a jointed arm . the jointed arm is also known as an articulated arm .
The
appendages of the robot manipulator give the manipulator its various axes of
motion . These axes are attached to a fixed base , which , in turn ,Cnc machining is secured
to a mounting . This mounting ensures that the manipulator will remain in one
location。
At
the end of the arm , a wrist is
connected . The wrist is made up of additional axes and a wrist flange . The wrist
flange allows the robot user to connect different tooling to the wrist for
different jobs
The
manipulator’s axes allow it to perform work within a certain area . This area
is called the work cell of the robot , and its size corresponds to the size of
the manipulator . Fig.2 illustrates the work cell of a typical assembly robot .
As the robot’s physical size increases , the size of the work cell must also
increase .
The movement of the manipulator is controlled by actuators , or drive
systems . The actuators , or drive system , allows the various axes to move
within the work cell . The drive system can use electric , Cnc machining hydraulic , or
pneumatic power . The energy developed by the drive system is converted to
mechanical power by various mechanical drive systems .The drive systems are
coupled through mechanical linkages .These linkages, in turn , drive the
different axes of the robot . The mechanical linkages may be composed of chains
, gears ,and ball screws.
