Chassis Specification Units, such as the Opaque Computing EXB-8505, are modules placed in robot bodies designed to inform the controller of that body's exact power requirements and other parameters. They are configured using a standard space-separated field-value format, with comments marked by preceding hash signs (#). This chapter will describe the fields and ranges supported by Companion 8.5, as well as the ATOS/E 12.2 and TESI 1.0 addons.

To set up your CSU, place the configuration file inside of the CSU's contents using the Edit Tool, and then install the CSU module into the robot's chassis. Example files suitable for most common chassis types can be found on the NSIS wiki. This file may be changed at any time as needed, and will automatically be reloaded by the system.
