Robotic Factory makes its return back to Gold and gains additional Crit Chance scaling to differentiate between tiers.
Similarly, 
Bunker has received a rework to now be a Robotic Factory for Shield items, also starting at Gold.
With both of these items fulfilling similar roles (and Robotic Factory much more accessible), Dooley now has a very powerful and flexible strategy to build towards in the mid to late game.
While Bunker and Robotic Factory are clearly different, they can actually fulfill the same role when playing a Friend-based build. Dooley has many Shield Friends that are worth using, giving you the option to make do with whichever one you find.
This is a big advantage since it increases the consistency of the archetype. The Large item pool is generally quite Small, so having two times the odds makes it fairly reliable if you look hard enough.
For this particular build, we'll be looking at Kripp's Bunker setup that capitalizes on two Shielded enchantments. Understand that the base items without enchants will not work in this case, so if you're looking to assemble something similar, you may need to modify depending on whether you're using Bunker or Robotic Factory.
Companion Core is the ideal Core if you're looking to flex between builds. Haste is always valuable, and you won't have to go out of your way to find additional sources. 
Armored Core is a solid alternative if you're leaning towards a Bunker board.
Most of the time you'll probably want more Small items instead of the two Medium-sized Friends shown here. However, since both of the items are Chargeable they move quick enough to support the Companion Core on their own.
Kripp had a Restorative enchant on the Companion Core, but among all enchants of the build it's the least relevant.
Harmadillo relies on having a way to quickly spam Shield triggers so it can rapid fire for a ton of Damage. With 
Duct Tape no longer in Dooley's item pool it's a lot harder, but with Shielded enchants it's extremely doable.
While enchanted items aren't exactly something you can rely on, it's worth mentioning that Shielded enchants are a bit more common thanks to Kev's Armory. An early (and lucky) visit can give you an easy build path to follow.
Race Carl can be an incredibly efficient Damage-dealing with the right support, and with a Shielded enchant it'll be equally as protective. Combined with Bunker and Harmadillo creates a ridiculous combo, looping the items like crazy.
Normally more Haste support is necessary, but thanks to another supporting item (see below) this build can get around it.
Fiber Optics lets you use your fastest item to Charge another item. As long as you can maneuver proper positioning, this can create an insanely fast engine beyond normal capabilities. This is what helps Race Carl make up for the lack of Haste.
It's worth noting that it only counts your leftmost and rightmost active items, and so it's possible to place passive items on either border and it won't interfere with the effect.
Command Ship is an exceptional skill provided you have a Vehicle, which aren't always common. Race Carl fills this role, lowering the Cooldown of the rest of the board.
Brick Buddy is another item that can fulfill the Friend + Vehicle tags, while also being a Medium-sized item.
Flashy Pilot is another powerful Vehicle skill that essentially gurantees maximum Crit rate across your entire board. It's arguably the strongest Crit scaling skill in the game, to the point where you can often pick it up before even acquiring a Vehicle.
Even at Silver tier it's still 10% Crit per usage, meaning with a fast enough Vehicle you can scale it up quickly.
Improvised Protection with Flashy Pilot unlocks insanely powerful Shield scaling that can help carry the build into the late game. Plus since Multicast is a huge component, it's only a matter of seconds before your Shield values begin to take off.
Similarly to Flashy Pilot, it's a strong enough skill that can be worth picking up before solving your Crit Chance. It doesn't take much to make it at least useable, but with proper support it'll be a build-defining skill.
