We show how to interleave our API with planning and replanning in Prolog to move a robot through an unknown environment. The presented API is divided into two abstraction layers. Low level predicates control individual sensors and actors, higher level predicates control user-defined robots consisting of several sensors and actors. The connection between the parts of the robot and an SWI-Prolog interpreter running on the robot is established via ev3dev.enlogic programmingSWI-PrologroboticsLEGO EV3ev3devText/Conference Paper10.18420/inf2019_ws411617-5468
