Rexroth Solution:

  • Rexroth MKK ball screw driven modules
  • Rexroth Omega linear module OBB belt-driven linear slide
  • Rexroth IndraMotion MLC motion logic controller

Key Insights & Considerations:

  • Handle Heavier Loads: With a Cartesian robot, a payload above 20 kg is no problem, which makes it more economical than SCARA or six-axis robots by permitting downsizing mechanics, using smaller components and less complex controls.
  • Fit Tough Orientations: For a high-volume medical pipette manufacturer, space was tight. The manufacturer was able to use compact Cartesian robot modules to achieve the required precision while meeting their space constraints.
  • Widen Travel Range: Cartesian robots also make sense when the application involves long spans. In one example, a gantry system was constructed of linear modules for an automated storage and retrieval system. The X-axis was nearly 10 meters long. A SCARA or six-axis system cannot handle that travel range.
  • Simplify Configuration: Bosch Rexroth offers EasyHandling configuration tools that can create a linear motion system for single- or multi-axis systems in just a few clicks. All you need to know is the mass that needs to be moved and the required stroke.
  • Pre-Parameterize Controls: Pre-parameterized function blocks enable coordinated motion of several axes to be loaded into the controller at the factory. End-users can program in simplified robotic mnemonic code according to their particular application.
  • Assure Safety: Integrated safety circuits can utilize intelligent servo drives equipped with safety capabilities directly at the drive level, enabling a faster response.
