Abstract

This paper proposes a framework for controlling the behaviour of simulated robots through high-level instructions. We assume that each robot is not only capable of performing autonomous and complex movements, but also capable of interacting with each other by performing actions and reacting accordingly to the changes of the environment. These instructions are originated from the animator's scripts and may also be an autonomous response to the interactions between the animated agents. The assumption that instructions have adaptive planning of behaviours composed by sub-instructions permit us to build increasingly complex instructions to be built. The system exploits AI techniques including frame, blackboard, planning, and rules.
