What Robostar does

Robostar (로보스타) is a South Korea-based industrial robotics manufacturer headquartered in Suwon, operating for more than 25 years as a subsidiary of LG Electronics. The company designs and produces a broad portfolio of industrial robots — including SCARA, articulated, Cartesian, and parallel (delta) robots — as well as wafer and glass transfer robots, automated guided vehicles (AGVs), autonomous mobile robots (AMRs), mobile manipulators, and proprietary robot controllers. Its technology stack features a PC-based controller architecture, the proprietary RRL (Robostar Robot Language) programming environment, conveyor tracking capability, and AI-enabled vision systems used for part recognition and camera-based position detection.

The company serves manufacturers across electronics, semiconductor, display, battery, automotive, and logistics verticals, with stated customers across Korea, North America, China, and other Asian markets. Its business model historically rests on equipment sales — robots, controllers, and integration services — supplemented by a growing smart-factory SaaS offering targeted at small and mid-sized manufacturers. Robostar is also positioning into the semiconductor equipment value chain with front-end modules such as EFEMs (Equipment Front End Modules), wafer transfer robots, load ports, and pre-aligners, while extending service reach internationally (including the United States) via dispatched engineering teams.

Commercial expansion is anchored by an unusually high-touch sales motion: senior leadership reportedly engages directly with approximately 500 customer accounts per year. The combination of a large parent (LG Electronics), a multi-decade installed base feeding service and consumables revenue, and a transition from pure equipment sales toward recurring software and semiconductor-grade subsystems forms the core of the operating model.
