A ROMER Arm is a term for a portable coordinate measuring machine ROMER, a company Acquired by the Hexagon AB group, and part of the Manufacturing Intelligence division, designed the ROMER arm in the 1980s to solve the problem of how to measure large objects such as airplanes and car bodies without moving them to a dedicated measuring laboratory.
The arm has 6 or 7 joints and operate in the 3D world - It has 6 degree of freedoms- 3 for rotation and 3 for translation.
The measuring arm is brought to the part, which is possible because of the light weight of the system (less than 20 pounds).
The word ROMER comes from a combination of the two founders' names: Romain Granger and Homer Eaton.
In August 2018 Hexagon Manufacturing Intelligence renamed the product to the Absolute Arm consigning the name ROMER to the history books.
