Frequently Asked Questions

Quaco Robotics

How do we test DUTs with different heights?

The QUACO Pro D robot is designed with adjustable height functionality to accommodate DUTs of varying heights. There are two methods to adjust the robot’s height:

  1. Via the Front HMI Display Unit:
    • Navigate to Menu > Height Adjustment on the display unit.
    • Use the right-side navigation buttons to set the desired height (displayed in millimeters).
    • The maximum height adjustment is 275 mm from the test bench level.
  2. Using the Quaco Studio Software:
    • During HAPI creation or test execution, the height can be configured through the API triggers.

Note: For optimal safety and efficiency, we recommend assembling all DUTs on a uniform plane to minimize testing time and avoid repeated adjustments.
