What is a CRG file?

CRG files mostly belong to OpenCRG. CRG files serve two main purposes:

Road Surface Description: They store detailed road geometry data. This data supports vehicle simulation by recording aspects like slopes, curves, and surface contours. They conform to the OpenCRG standard. You can learn more on the OpenCRG webpage.
Choregraphe Project Files: In this role, CRG files hold robot behavior instructions. They are used within the Choregraphe development environment and the internal format is sometimes labeled as LinuxAr. More details are available on the Aldebaran website.

FilExt.com note: The correct software must be used to open these files. For road surface data, specialized vehicle simulation tools are required. For robot behavior, the Choregraphe editor is needed.

How to open CRG files

CRG file format:

A file format defines how the data in the file is structured. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the CRG files is as follows:

The CRG file extension is not widely used. Such a file includes various formats for various programs. But the following two file formats are common:

40% of all CRG files start with the bytes 24 43, which are crucial for this file format. These files contain neither text nor words, but only data. The files are 4 KB to 51 MB in size, with a median of 1 MB. The file type was developed only in the last few years. Certain words are almost always found in the files, such as reference_line_start_u, $ROAD_CRG, file and 0000000000000000e. The file name belgian_block.crg or BelgianBlock.crg is typical for these files. These files can be linked to belgian, block, road, country, demo, handmade and axis.
20% of all CRG files are based on the popular LinuxAr file format. This file format is an archive created by the Unix archiver "ar", which stores multiple files together in a single archive, that allows each one to be separately retrieved later. The contents of these files cannot be read by a human; only a computer program can interpret the data. Most of these files are 8 KB to 4 MB in size. The keywords !<arch>, debian-binary/ 0 0 0 100644 4 `, control.tar.gz/ 0 0 0 100644 10240 ` and NC8(lC are typical for these files. The following filename is common: Dances The Macarena.crg.

The remaining 40% of all CRG files are files with no common format, the following 4 formats can be found: Calamus Raster Graphic bitmap and Emacs. Tagged as vector, extended, straight, banked, curved, bseci or name.
