Because of the highly rigidity, the Cartesian/Gantry
Robots are very accurate and repeatable but they lacks flexibility
as they cannot reach around objects. Due to their mechanical
structure, these robots are very easy to program and visualise.
However, they require large volumes to operate. Their linear
joints are difficult to seal and this makes them unsuitable
for working in damp and dusty environments.
The Cartesian Coordinate Robot's relatively simple design
and straightforward operation make it highly desirable in
manufacturing. Because the individual axes can be easily
replaced, downtime is reduced and maintenance costs are
kept to a minimum. In addition, the entire system can be
disassembled into its component parts for use in multiple
single-axis applications. Most importantly, Cartesian Coordinate
Robot systems are inexpensive compared to other more expensive
and more complex robots.
