The Block Division Diagram (BDD), shows all component classes (each block defines a class) in a Rosbee Robot, as well as the number of components and the hierarchy between components.
Connections with a black diamond-shaped end mean that a lower level class (on the side of the arrow tip) is a part of a higher level class (on the side of the diamond).
Connections without a diamond show the way in which classes are linked to eachother and the direction of any flow of material, data and energy.

The Internal Block Diagram (IBD) shows all components used to build a Rosbee Robot, as well as all connections, flow of material, data and energy. Connections are represented in the same way as in the BDD.
