Robots manufacturer Stäubli Robotics and 3D measurement software company Metrologic Group jointly developed the first Coordinate Measuring Robot (CMR) achieving a 100-micron 3D absolute and trackless accuracy.

The 3D metrology market sensed robots were coming. They are definitely there, with Stäubli Robotics and Metrologic Group announcing a jointly developed robotic solution competing with the classical CMMs on the accuracy field, with no tracking devices associated.

This first of its kind Coordinate Measuring Robot (CMR) combines Metrolog X4 i-Robot –Metrologic Group’s robot-dedicated 3D measurement software built on over 35 years of expertise in 3D error mapping and compensation– with Stäubli’s 6-axis TX90 and TX200 series robots. The partnership allows the highly efficient mechanical robots developed by Stäubli achieving +/-100-micron accuracy in touch trigger mode, in a 1 cubic meter volume, and +/- 150-micron in optical laser scanning mode. As all the Metrologic Group’s software suite does, the CMR can accommodate any kind of touch probe or optical sensor, of any make.

One single Software Solution

Metrolog X4 i-Robot not only improves the accuracy and the integration of laser sensors and touch systems; it fully controls the robot and makes the most out of the inspection results; all that in one single solution. Silma X4 i-Robot is used for any robot virtual programming based on inspection features: it makes it easy for any metrologist to program CMR measurements as simply as with any classical CMM.

Innovation with Many Benefits

The CMR delivers 3D metrology laboratory accuracy beside the production line and brings many benefits:

• It reduces investment cost as no tracking device is necessary (neither laser tracker nor camera needed);

• It increases measurement accessibility as no tracker system limits the measurement area (no blind spots);

• Moreover, fully equipped with Metrologic Group software suite it is a 4.0 factory-ready solution that is flexible, reliable and easy to use.

"With the Coordinate Measuring Robot (CMR), Stäubli Robotics demonstrates its expertise in solutions in which velocity, precision and dependability are paramount,” says Jacques Dupenloup, Stäubli Robotics Sales Manager France and Benelux. “The CMR will perform in most harsh environments with the same efficiency as in metrology labs. That makes it the perfect solution for industrials that require maximum performance near the production line.”

"We are very proud to bring this innovation to the robotized 3D metrology market”, says Bertrand Gili, Metrologic Group President. “It demonstrates, once again, that innovation and technical break through are part of Metrologic Group’s DNA. The Coordinate Measuring Robot (CMR) is the first ‘off-the-shelf’ robotic solution entirely developed by a robot manufacturer and fully integrated by Metrologic Group. It thus delivers ease of use, flexibility, and reliability in the demanding industrial environment. For us and for its future users, it is robotic inspection made easy.”
