Industrial robot names are typically created by using by the manufacturer, series, and model number. These three divisions help distinguish today's industrial robots.
Series Name - Each robot company has its own approach to naming series or robot lines. Some series names are connected to application, such as Motoman's CR (clean room) robots. They can range from acronyms to entire words. Other manufacturers' series are part of the model name, such as FANUC LR Mate series.
Model Name - Within each series, individual robots are distinguished by model names. Model names are typically associated with payload, like the Motoman SK 6, whose payload capacity is 6kg. Models are sometimes given even more distinction by adding an additional letter to denote specific characteristics of that robot. These letters can be related to mounting specifications, build, controller, etc. The FANUC R-2000iA/125L has a 125kg payload, but the L indicates that this robot is a long arm version.
