Two Case Studies for Jazzyk BSM

Recently, we introduced

Behavioural State Machines

(

BSM

), a novel programming framework for development of cognitive agents with

Jazzyk

, its associated programming language and interpreter. The

Jazzyk BSM

framework draws a strict distinction between

knowledge representation

and

behavioural

aspects of an agent program.

Jazzyk

BSM

thus enables synergistic exploitation of heterogeneous knowledge representation technologies in a single agent, as well as offers a transparent way for embedding cognitive agents in various simulated or physical environments. This makes it a particularly suitable platform for development of simulated, as well as physically embodied cognitive agents, such as virtual agents, or non-player characters for computer games.

In this paper we report on

Jazzbot

and

Urbibot

projects, two case-studies we developed using the

Jazzyk BSM

framework in simulated environments provided by a first person shooter computer game and a physical reality simulator for mobile robotics respectively. We describe the underlying technological infrastructure of the two agent applications and provide a brief account of experiences and lessons we learned during the development.
