CCRs are highly configurable,
rectilinear robot systems which, in a basic
configuration, include an X and Y axis.
Three axis CCRs, incorporating an X, Y,
and Z axis, are also common for positioning
tools, such as dispensers, cutters, drivers,
and routers. Each of the axis lengths are
selectable, with the ability to attach different
types of Z-heads. Payloads and speeds vary
based on axis length and support structures.
CCRs are also typically very repeatable,
have better inherent accuracy than a SCARA
or jointed arm, and perform 3D path-dependent
motions with relative ease. However, the
CCR’s key feature is its configurability
– the ability you have to configure
and size the CCR to best meet your application
needs.
Best of all, you pay only
for the axes you really need! If two axes
are required, you buy a 2-axis CCR and save.
If three axes, you buy a 3-axis CCR. If
four axes are needed, you have the choice
of using a SCARA or a CCR system, which
ever best meets your application needs.
If odd configurations are required, then
the flexibility of CCR systems gives you
many more possibilities to consider.
A gantry robot is
a special type of Cartesian robot whose
structure resembles a gantry. This structure
is used to minimize deflection along each
axis. Many large robots are of this type.
The X, Y, and Z coordinates of a gantry
robot can be derived using the same set
of equations used for the Cartesian robot.
