A robot system and method for the repair and/or inspection of cast surfaces in an automated comprising a robotic manipulator of at least 4 degrees of freedom and a gripping mechanism which allows taking a repair device from a tool holder rack located at one of its sides and moving it through a defined path to a repair and inspection area, where a repair process will be carried out in a sequential and programmed way to a number of cast faces to be defined. Additionally, the system allows carrying out an inspection process of the surfaces in a sequential and programmed way through the use of a vision system by taking from a tool holder rack or carrying an advanced vision system for the inspection of surfaces.
