BDI Architecture for SARL

This demo show a (still) very simple way for creating a BDI reasoning agent using jason's Engine

Features

• Load .asl (Agent Speak) files
• Call actions defined in SARL agents and / or Capacities
• Translate event into perceptions and Messages with the following rules (TODO)
  • If the Event is of Type KQMLMessage it will be translated as an Message in Jason
  • Any other type of event will be translated as a perceptions see [#SARL Event to Jason Perceptions translation]] and [[TODO]]

Maven Notes

Jason doesn't have a maven artifact deployed, so you have to install it before compiling. A copy of jason.jar (v1.4.0a) is distributed in the lib directory. To install it copy and paste the following in the root folder of this project.

$ mvn install:install-file -Dfile=lib/jason-1.4.0a.jar \
    -DgroupId=net.sf.jason -DartifactId=jason -Dversion=1.4.0a -Dpackaging=jar 

Then you can build the BDI demos using:

$ mvn clean install

Demos

All demos are defined in jason_demo_agents.sarl

The BDIAgent is the base agent used in all demos, only the ASL file it loads on initialization changes. Basically, each demo launcher is just other agent used only to spawn BDIAgent's with the right files.

You can run the demos using :

$ ./janus <FQN of Demo Launcher>

Factorial

A very simple factorial implemented in AgentSpeak

ASL File : src/main/resources/factorial.asl

Agent Demo Launcher: io.sarl.demos.jason.DemoFactorial

SARL Events

Simply print the events preceived.

ASL File : src/main/resources/sarl_events_perception.asl

Agent Demo Launcher: io.sarl.demos.jason.DemoSARLEvents

KQML Messages

Two agents in ASL exchanging messages.

ASL Files :

• src/main/resources/communication/bob.asl
• src/main/resources/communication/maria.asl

The ASL Agents are extracted from the communication demo of Jason without modification.
