Abstract
Virtual robot programming environments provide a visual interface for programming and simulating educational robots. Nowadays, simulation is the only way to assess the robot behaviour inside such environments, as there is no approach that supports the automatic analysis of the correctness of robot programs. This paper introduces an automatic approach for verifying robot programs written in the educational programming language ROBO. We give semantics for ROBO programs in the setting of CSP process algebra and automatically verify the properties of the programs using the FDR refinement checker. The verification approach has been defined considering programming exercises proposed in the literature on educational robotics. We illustrate the approach using sample programs written in ROBO and discuss how to integrate such an approach with educational tools.
