ROMER INFINITE 2.0

The new INFINITE 2.0 is ROMER’s easiest-to-use and most accurate articulating arm ever. New handling and performance features - along with patented infinite rotation, quick-change probes, exclusive wireless connectivity and battery power - provide INFINITE portability and measuring power.

The ROMER INFINITE 2.0 is available in 3 configurations:

    * ROMER INFINITE 2.0 Six Axis (sizes from 1.2m to 3.6m)
    * ROMER INFINITE 2.0 Seven Axis (sizes from 1.8m to 3.6m)
    * ROMER INFINITE 2.0 Plus - Six axis enhanced accuracy models (sizes 2.4m and 3.6m)

INFINITE 2.0 Plus models, with unsurpassed repeatability and volumetric accuracy, are ideal for the most demanding inspection tasks.

ROMER also offers system verification “in the field” with a NIST-traceable calibrated length standard with every arm. This allows the operator to easily verify and document system performance for ISO or vendor requirements.

In addition to INIFINITE 2.0, ROMER offers a complete selection of software and accessories to provide total metrology solutions.

Features

• Patented infinite rotation of the three principle axes allows inspection in difficult-to-reach areas.
• With the new TESA kinematic multiwire probe joint, you get unsurpassed measuring performance with a highly repeatable quick-change probe connection.
• Carbon fiber probes feature automatic probe recognition. When the probe is attached, the software automatically recognizes.
• New SpinGrip infinite-rotating grips at elbow and forearm provide two low friction grip positions for better ergonomics. SpinGrips allow Infinite 2.0 to “float” in the operator’s hands, maximizing accuracy and minimizing operator fatigue.
• Heidenhain encoders, manufactured to Hexagon Metrology specifications, offer “wide-track” bearing support that enhances performance.
• The compact wrist is a marvel of compact ergonomic design. The three programmable buttons control arm functions or act as a three-button mouse when the arm is used in “mouse mode”. When using the portable arm in mouse mode, the operator can control the computer cursor and software remotely, thus the operators’ hands never have to leave the arm when in use. The operator can perform the entire inspection cycle without physically touching the computer.
• The wrist also features an integrated digital camera for documenting setups and an LED worklight to illuminate inspection areas that are in shadow.
• Advanced carbon fiber arm tubes are strong, lightweight, thermally stable in shop floor conditions and feature a lifetime warranty.
• An improved, low-profile Zero-G counterbalance reduces operator fatigue and delivers effortless control in all positions, including above and below the centerline.
• An upgraded 802.11g WIFI connection - transmitting up to 6 times farther and 50 times faster than Bluetooth - allows the operator to position the computer where it is most convenient.
• A Li-Ion battery allows on-site inspection without AC power or cables. A sealed battery cover prevents contamination of the battery compartment or accidental dislodging of the battery.
• A quick-clip probe holster keeps three spare probes and the change key safe and handy.
• The universal mounting system attaches to a variety of bases, including a magnetic mount for a smaller footprint and simplified set-up.

a) Point Repeatability Test (also known as Single Point Articulation Test, or S.P.A.T.): Results analyzed via Range/2 method. The probe is placed within a trihedral seat or conical socket, and individual points are measured from multiple approach angles with maximum articulation of all of the principal joints. Each individual point measurement is analyzed as a range of deviations about the average value for the point locations. This test is to assess the arm’s ability to provide similar values of a point coordinate, when the arm is articulated through the maximum possible range of motion for that single point.

b) Volumetric Length Accuracy Test (Volumetric Performance Test): Results analyzed via Range/2 method. Volumetric length accuracy is determined by using certified length standards (included with all arms) that are measured at various locations and orientations throughout the measuring volume. This test most accurately represents the reasonable expectations for machine performance in practical measuring applications. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length.
