During the month of May’24 I had the opportunity to attend the INCOSE’s MBSE & AI Summit in Hyderabad. It was a very humbling experience for me to listen to some of the distinguished speakers like Dr. Ramki Raman and Mr. Dave Snowden.

Amongst many, one key take away was about the MBSE tool Capella and an introduction to the Arcadia method. Capella is an opensource MBSE tool available for free download.

There are a few good online tutorials in case anybody wishes to explore the tool.

Here’s a simple Physical Architecture that I created using the Arcadia method (Operations Analysis > System Analysis > Logical Architecture > Physical Architecture)

This model is for the hobby project (“Atom-Jr”) that me and my kids have been doing. Here’s a picture of the second proto of the Atom, the name of the robot that we assembled.

The objective is to make it an autonomous mobile robot capable of transporting upto 50kg of weight from point A to point B with minimal or no human intervention.

More about the Atom-Jr project can be found here!
