Metrolog X4 i-Robot is a unique software solution that effectively turns any industrial robot into a high-speed, shop-floor CMM. X4 i-Robot technology is suitable for all makes of industrial robots, and provides a production metrology solution that is accurate, reliable, very fast and extremely flexible.

Metrolog X4 i-Robot is perfectly suited for industrial applications requiring flexibility and productivity, while at the same time providing high metrological accuracy. The measuring accuracy is fully independent of the robot’s own positioning precision, as the measuring device is tracked independently. Metrolog X4 i-Robot is directly connected to the robot PLC controller, such that all robot movements are perfectly synchronized with the measurement activity. This means the robot trajectory is entirely controlled by a standard Metrolog X4 part program, and can instantly take account of alignment conditions.

How Does It Work ?

Metrolog X4 i-Robot is typically based on a high speed acquisition laser scanner attached to a multi-axes robot wrist. The robot, of any type or brand, and without specific accuracy, behaves like a simple tool holder. The measuring accuracy is provided by a separate tracking system (cameras or laser tracker) which continuously tracks the actual location of the measuring sensor in space. This means the positioning accuracy of the robot is not critical, as its position can be adapted "on-the-fly" according to the sensor location.

The main applications can be found in the automotive, aerospace and their sub-contractors for the manufacturing lines metrology control.

X4 i-ROBOT - The Future of Automated 3D Inspection

Measure parts with a Touch or Scan Robot inspection cell

Metrolog X4 i-Robot is completely independent of robot manufacturer or measuring device type. We can integrate any robot with any measuriong device, as long as the device is tracked independently.

Stand-alone or Fully Integrated Solution

As the system can integrate all types of robots, Metrolog X4 i-Robot is ideal for those looking to have a standalone, dedicated measuring cell, where parts are transported to the cell for inspection - just like a CMM !

However, Metrolog X4 i-Robot is equally at home on the shopfloor, fully integrated into in-process robots, similar to those used for weldingf and assembly. Any robot, any measuring device, anywhere.

Unrivalled Measuring Speed

Metrolog X4 i-Robot software allows a quick control of all geometrical characteristics of the part based on CAD definition, as well as a complete analysis of free form specifications such as flush and gap, sections, surface mapping, etc. High speed movement between measuring processes, and highly controlled vectoring when acquiring point clouds for perfect scan data, everytime.

No Robot Programming Necessary

Metrolog X4 i-Robot directly handles robot motions and inspection commands in one single part program. This means the robot is programmed directly through Metrolog X4 i-Robot (or offline using Silma X4), without any need for specialist programming of the robot itself. Any trained inspector or CMM programmer is able to program Metrolog X4 i-Robot directly, without any prior knowledge of the workings of robot PLC's.

Inspection programs can be easily modified, just like a CMM, without the interaction of a robot programmer. No other robot based inspection system is this easy to program !

Complete Flexibility

The solution can integrate additional robot cell axes such as 7th axis rail, rotary tables, or even multiple robots and measuring devices.

Metrolog X4 i-Robot is the first and only software product enabling an intuitive, all-in-one robot based inspection.

Key Features and Benefits

An Independent Metrology Chain

The measuring accuracy of the complete system is totally independent of the robot’s precision, eliminating the effects of robot drift, warm-up, backlash, etc.

This independence also negates the need for laborious, non-productive cyclic robot calibrations.

Perfect synchronization between measurements and robot

Programming with Metroilog X4 i-Robot is no different to programming a traditional CMM, apart from the fact that the CMM looks different. Simplified programming of the robot trajectory can be achieved directly from the CAD, with the software providing the ideal orientations of the robot axes.

Programming can be performed "on-line" at the robot, or alternatively in off-line mode using Silma X4, presenting massive time-savings for production applications. As is often the case, part programs need mofifying from time-to-time, and this is easily achieved by updating the sensor location and robot positioning directly through Metrolog X4 i-Robot.

Process integration using industrial robots

Robots provide a fast, lean manipulator for many types of measuring devices. Using Metrolog X4 i-Robot, you can choose almoist any make of robot, and any make of sensor to provide your desired solution. In the case of maintenance, it is easy to exchange robots and carry on measuring - try that with a CMM !
