RS4 Integrated Scanner

The ROMER Absolute Arm with Integrated Scanner is an all-purpose portable measuring arm system designed to meet the needs of almost any measurement application, whether scanning or touch-probing. 

The fully-certified and integrated RS4 laser scanner is designed to capture 3D point.

Portable measuring arm with fully-certified and integrated RS4 laser scanner designed for faster-than-ever 3D data capture across a range of surfaces and applications.

The ROMER Absolute Arm with Integrated Scanner is an all-purpose portable measuring arm system designed to meet the needs of almost any measurement application, whether scanning or touch-probing.

Switching seamlessly between tactile probe measurement and laser scanning at any time, the ROMER Absolute Arm with Integrated Scanner is ideally suited to point-cloud inspection, product benchmarking, reverse engineering, rapid prototyping, virtual assembly and CNC milling.

The fully-certified and integrated RS4 laser scanner is designed to capture 3D point data across a range of surface types. It requires no calibrations, warm-up time or additional cables and controllers. It is totally integrated. With a ultra-wide laser stripe of up to 150 mm, the RS4 can capture 752,000 points per second, reducing the number of passes required to fully scan a part and minimising overall measurement time.

The accuracy of the complete scanning system is fully verifiable and traceable, ensuring users always have complete confidence in the exactness of their measurements. The ROMER Absolute Arm with Integrated Scanner is available at three different accuracy levels – 73, 75 and 77 series – to ensure the right configuration is available for any measurement application.

 


 

 
Measurement Volume
Available in six sizes providing measurement volumes with diameters between 2.0 m and 4.5 m.

Automatic Probe Recognition
Swap probes at any time without the need to recalibrate – repeatable mounting allows probe changes on the fly according to measurement needs.

Robust Feedback
Instant visual, acoustic and haptic feedback allows the system to be used accurately and efficiently in even the harshest industrial environments.

Total System Certification
Full B89.4.22 certification for the entire arm and scanner system, with additional certification according to VDI/VDE 2617-9 also available.

Absolute Encoders
Referencing and warm-up time is a thing of the past – just switch on and start measuring.

Arm Balance
Optimised design echoing the uneven arm-length ratio typical in industrial robot design makes the arm lighter and easier to use.

Zero G
Counterbalance system minimises torque in the base of the arm, allowing effortless user movement, greater accuracy and a wealth of mounting options, including lightweight tripods and magnetic and vacuum bases.

SmartLock
Lock the arm safely in the rest position when not in use, or conveniently fix the arm in any intermediate position during measurement.

Carbon-fibre Structure
High-tech materials make arm measurement secure and thermally stable under any environmental condition.

SpinGrip and SpinKnob
Rotating low-friction handling grips improve ergonomics, minimise user fatigue, provide thermal stability and maximise accuracy.

Ergonomics
Wrist structure, hand grip design and intelligent button positioning allow for total control over arm alignment and adjustment.

RDS
Proprietary software featuring SMART – Self-Monitoring Analysis and Reporting Technology – that manages the arm in the field by monitoring diagnostics including shocks and temperature.

RDS Mobile
Compatible with all WiFi enabled systems, the RDS Mobile app allows users to connect directly from a mobile device to access simple probing and scanning functions and diagnostic operations.

Feature Packs
Easily interchangeable Feature Packs enhance functionality for all arm models, from WiFi connection and laser scanning to full battery-powered operation.

Compatibility
Works with all major metrology software packages.
