Challenges of the telescope control system for large robotic telescopes

The New Robotic Telescope (NRT) with a collecting area of 4pi square meters will be the largest fully robotic telescope in the world. This contribution is focused on the design of the telescope control system, summarizing the state of the art and proposing a software architecture and a development roadmap that reflects the needs and requirements for this facility. This pioneering effort for a large robotic telescope aims also to provide standards for future similar facilities.
