You don't get to be the leaders of the Trade Federation by spending on novelties.įinally, the grav unit used to transport Solo probably needs to be able to transport a large variance of weight, there's probably a few bounties Fett has gone after that have been heavier than a human in a frozen block As for the walking holo-emitter used by the Trade Federation, they were thrifty, they knew they didn't need a holo-emitter using grav emitters, it would be a waste of credits.

Things like hovering chairs seem like a waste until you consider how needlessly opulent the Jedi were before they attempted their coup. Legs work fine, especially since these aren't comfort vessels. Anti-grav tech could help with this, but each emitter would have to be on variable geometry motors continually adjusting with very uneven terrain. This means they are heavy and have a lot of room for troops and equipment. Other walking units, like the AT-AT's and the ST's, are made for uneven terrain and fast troop deployment.

Can you imagine an R2 unit rolling through a Jungle like Endor? It's ridiculous. Your average R2 unit will just be rolling around the hangar bay between the ship and the maintenance bay. Anti-grav is still more expensive than wheels.
