I’m new at capella and I’m trying to model a robot car which have the main function of transport heavy loads. The car will be controlled by an operator via remote control, which send commands to a receiver at the car, and the receiver send the commands to the control unit.
I’m a little confused about some steps of the system analysis.
I’ve set some capabilities to the car: move/manage, carry/alocate load, modify structure, provide safety.
Considering the move capability move/manage, I’ve done a SAB diagram considering the operator and the system. The system function that I considered where “modify angle of the wheels”, “accelerate”, “brake”. And the functions of the operator where “Accelerate car”, “brake car”, “change direction”.
But really don’t know if this is right, because for me this is kinda ambiguous.
Also, I’m confused if for every capacibility I need to do a Scenario diagram, or i can just do a SAB diagram and uses functional exchanges to show the relations between the functions.
Can you guys help me to clarify this ideas?
I’ve saw some examples and books aboud arcadia and capella, but the examples there did not helped me in my project context.
I started to use capella to help me and my colleagues to develop the software for the Car.
