When blue and green conveyor belts are connected, a robot can take advantage of both, as long as the blue conveyor moves them onto the green conveyor.

In this example, a robot on the far-right blue conveyor belt space is conveyed twice by the blue conveyor (Step 1 of Board Elements) and then once by the green conveyor (Step 2 of Board Elements). Moving 3 spaces for free is going to find you in the lead in no time!

Conversely, if your robot is conveyed by a green conveyor belt (in Board Elements Step 2) onto a blue conveyor belt, they don’t take advantage of the blue conveyor belt, as it already resolved in Board Elements Step 1.
