Some robots don’t look like “robots” at all. Sometimes these are called Cartesian Systems, with X-Y-Z, or X-Y-Z-Theta axes of motion. Other times they are referred as Gantries, with similar layouts.
Festo’s Cartesian systems are a part of their “Handling Systems” group. Their wide variety of belt-driven and ball screw driven actuators can be configured in almost limitless permutations – with each unique system available as a single part number and with a lead time of only a few weeks!
Denso’s XR-Series is a four-axis, compact gantry robot. It includes a ceiling-mounted SCARA robot, combined with a long-stroke Cartesian axis. In many applications, these can be used without an additional conveyor, saving up to 20% in capital-equipment costs. ANSI and CE compliance allows global deployment.
