==Summary==
*The B.O.B Control is a building unlocked at Builder Hall level 9. The B.O.B Control does nothing when initially built, and will only serve as a distraction defensive-wise. However, once upgraded to level 5, it enables the B.O.B's Hut to be built in the Home Village, allowing B.O.B to function there.
*Upgrading the B.O.B Control does not take time or resources, but instead, a certain prerequisite must be completed (and the Master Builder or O.T.T.O must also be available to upgrade the building). To upgrade the B.O.B Control to level 5, four such prerequisites must be satisfied in any order.
**Gearing up a , , and a Mortar in the Home Village. This requires a level 7 Cannon, a level 10 Archer Tower and a level 8 Mortar respectively in the Home Village, and a level 4 Double Cannon, a level 6 , and a level 8 Multi Mortar in the Builder Base.
**Upgrading any troop to level 18 (which requires Star Laboratory level 9).
**Upgrading any defensive building in the Builder Base to level 9.
***Though having defensive capabilities, O.T.T.O's Outpost does not count as a defense for this purpose; do not count either.
**Upgrading the Battle Machine and Battle Copter to a combined level of 45.
==Upgrade Differences==
The B.O.B Control undergoes significant visual changes at levels 2 and 4.
*When initially constructed, the B.O.B Control is a stone platform with wood planks painted black hammered on as a base. There is a loose ramp made out of nailed wooden planks. There is a hammer and some nails, along with a curved machine part with a gold ring and fitting.
*At level 2, the hammer and nails are removed as a stone table is added and the machine part is attached to the table, a wooden wheel wheel is leaning on the side of the table. Two metal latches are placed on the floor.
*At level 3, the table gains a wooden extension which covers the machine part. B.O.B's eyes, O.T.T.O's arm, and wind-up screw are placed on the table while the wheel is moved to the floor.
*At level 4, a structure resembling a builder hut is added on the platform, with four wooden pillars and stone wall with a window, concealing everything inside. The roof has a slot resembling an electric outlet with a spanner next to it instead of a saw and a hammer forming a cross.
*At level 5, a coil with a golden base and a golden orb is added to the top of the hut, which resembles the coil on O.T.T.O or B.O.B.

==History==
Patch 	Description
June 18, 2019 	Added the B.O.B Control (then known as the O.T.T.O Hut), with 5 levels.
March 30, 2020	The visual boost effect for an O.T.T.O Hut can now be seen when the Clock Tower is active.
April 12, 2021	Fixed a bug where progress can wrongly be credited towards O.T.T.O tasks.
May 15, 2023 	Renamed the O.T.T.O Hut to B.O.B Control, and changed its upgrade requirements to be more flexible.
*As the level 5 upgrade had its requirements increased, mainly the troop level requirement to account for pre-upgraded troops, players who had completed the O.T.T.O Hut prior to the update kept their upgrades and the associated rewards.
==Trivia==
*Since B.O.B Control requires gearing up all 3 buildings currently available to be geared up, the upgrade effectively requires players to have Town Hall level 10 or above as the Mortar gear up requires the Mortar to be level 8 which requires Town Hall 10.
*The B.O.B Control has the same amount of hitpoints and Build Time as a Builder's Hut from the Home Village.
*The B.O.B Control is the only building that requires other non-central buildings to be upgraded to a certain level or modified to be upgraded, unlike all the other buildings, which take time and cost resources and central building level.
*The B.O.B Control, the Battle Machine Altar, and the Battle Copter Altar are the buildings in Builder Base that have the least amount of hitpoints.
*The B.O.B Control and the are the only upgradable buildings in Builder Base to have the fewest levels, which is 5.
*The B.O.B Control is the third Builder's Hut that does not cost gems, the others are Builder Hall, O.T.T.O's Outpost, and B.O.B's Hut on the main Home Village.
*Since the B.O.B Control requires a level 9 defense, upgrading the Multi Mortar may be the most convenient option because gearing up the Mortar requires Multi Mortar to be at level 8, which only needs one more upgrade to satisfy another requirement.
