Previously, the plan language cc-Golog was introduced for the purpose of specifying event-driven behavior typically found in robot controllers. So far, however, cc-Golog is usable only for projecting the outcome of a plan and it is unclear how to actually execute plans on-line on a robot. In this paper, we provide such an execution model for cc-Golog and, in addition, show how to interleave execution with a new kind of time-bounded projection. Along the way we also demonstrate how a typical robot control architecture where a high-level controller communicates with low-level processes via messages can be directly modelled in cc-Golog.
