Most in-demand robot type?

[Nemo]

Here's what I think about Worlds alliances:

1) One robot doing 3 tote auto stack (plus 3 bin set if they can do it) with the other two robots racing to pull two cans each during auto

2) All three robots can collect and stack totes effectively, with at least one being a landfill specialist and at least one being a human loading specialist

3) Either all of the robots are capable of capping their own stacks, or one of the stacking robots is capable of quickly picking up bins and capping one other teams' stacks.
