Control Mechanisms for Computer Animated Agents

Fernando W. Silva, Antonio L. Apolinário Jr.Ricardo C. FariasSilvia S. C. Botelho, Luiz M. G. Gonçalves

We introduce basic mechanisms and tools as support to perform virtual animated agents. We use a control theory approach dealing with physics specifications and constraints, including dynamics and kinematics issues, providing a well structured way to control the agent resources. We validate the mechanisms by presenting two virtual agents with different structures (sensors, actuators, and dynamics) which have used them. As practical results, the animated agents are able to autonomously perform different purpose tasks in a virtual environment, like a visual monitoring of its neighbor- hood, progression tasks onto a rough terrain, and visually guided reaching and grasping manipulation.
