Clock-model-assisted agent’s spatial navigation

Intelligent agent's navigation remotely controlled by means of natural language commands is of great help for robots operating in rescue activities or assistive aid. Whereas full conversation between the human commander and the agent could be limited in such situations, we propose thus to build human/robot dialogues based directly on semantically meaningful instructions like the directional spatial relations, in particular represented by the clock model, to efficiently communicate orders to the agent in the way it successfully gets to a target's position. Experiments within real-world, simulated scenario have demonstrated the usefulness and effectiveness of our developed approach.
