You also have to pick up the panel at the same height as level one anyway. So I’m not sure how you could specialize with hatches on level 2&3 since you will always have to pick it up at level 1 height.
I suppose it would be more of a theoretical niche. Since you’re right, it wouldn’t really be logical on account of picking up from the station at level 1 height.
Not that I think anyone would use it, but you could have a lift which only raises the hatch panel, and has a fixed puller at the feeder station level and fixed pushers at the two upper levels. For CARGO, most will pick up at ground level anyway.
More typically, I was thinking of teams who sacrificed speed (likely because of a higher CoG) to do the L2 & L3, and it might be more effective for them to continue scoring at those levels and let faster short robots do the L1.
If a team were to actually do this, they didn’t understand this year’s game. To make your robot even more complicated to AVOID level 1 would be ridiculous.
I could see a match strategy that a level 1,2,3 robot only did the top two levels if they were on an alliance with a level 1 specialist. But I don’t think that this would be specialization.
