FREVO and Modelio

FREVO

FREVO  is an open-source framework to help engineers and scientists in evolutionary design or optimization tasks. FREVO automates the problem setup phase, makes it straightforward to define local intelligence and interactions and performs a search for best fit solutions with genetic algorithms. FREVO is integrated directly into the CPSwarm Workbench.

Open-source FREVO components:

 

  • EmergencyExit: is a problem component in FREVO. Multiple swarm members move in a simple 2D discrete environment and try to find one out of the two emergency exits. In each discrete time step, a member senses the neighboring cells and moves to a free cell. When a member reaches an emergency exit, it is removed from the environment. The goal is that all members exit the environment. For more detail, please consult this paper ‘Modelling a CPS Swarm System: a Simple Case Study‘. Click here to download.

Modelio

Modelio is an open-source modeling environment which can be extended through modules to add functionalities and services. Modelio is used for all modelling and requirements management within the CPSwarm project.

Models in Modelio:

  • Spiderino: this project is a model of the Spiderino, a robot platform for swarm research. The current model includes a number of modeling elements for sensors, actuators, and communication that serve as input/output to a behavior. Click here to download.

 

  • EmergencyExit: this is a model of a swarm of robots that needs to find an exit in an unmapped environment. The example problem is further used to show the integration of Modelio, a UML/SysML modeling tool, and FREVO, an optimization tool in the CPSwarm workbench.
