ARMOR

Although composed of durable alloys or resilient plastic polymers, robots are easily damaged. For this reason, combat models are usually equipped with some form of armor, depending on the robot's frame.
A robot can be equipped with a suit of removable armor (identical in form and function to armor worn by organic characters), or it can have armor integrated into its frame. A robot may be limited to one type or another depending on its shape, size, and frame. Liquidstate robots cannot have armor of any sort.
Removable Armor: Anthropomorphic biodroids and bioreplicas typically wear removable suits of armor, which provides an equipment bonus to Defense. A robot equipped with removable armor must have the appropriate Armor Proficiency feat to gain the armor's full equipment bonus, and the armor's maximum Dexterity bonus applies. Armor penalties on Balance, Climb, Escape Artist, Hide, Jump, Move Silently, and Tumble checks apply as normal.
Integrated Armor: This type of armor is welded or otherwise fixed securely to the robot's frame. Integrated armor provides an equipment bonus to Defense. Robots equipped with integrated armor suffer no armor penalties if the armor is installed properly. Improperly installed armor causes the robot to take a -10 penalty on Balance, Climb, Escape Artist, Hide, Jump, Move Silently, and Tumble checks.
Installing integrated armor on a robot requires a Craft (mechanical) check (DC 20). The check is made after investing an amount of time determined by the robot's size: Colossal 24 hours, Gargantuan 12 hours, Huge 6 hours, Large 3 hours, Medium-size 2 hours, Small 1 hour, Tiny or smaller 30 minutes. Integrated armor can be removed in half the time with a successful Repair check (DC 20).

INTEGRATED ARMOR

Different types of integrated armor are presented below. Only one type of armor can be installed on a given robot.
Equipment Bonus: The equipment bonus that the integrated armor provides to the robot's Defense.
Weight: How much weight integrated armor adds to the robot's weight.
Speed Penalty: The amount by which the armor reduces the robot's speed, given in feet. If a robot's speed drops to zero because of the penalty, it cannot move (the armor is too heavy for its frame).
Purchase DC: The cost of the integrated armor (or its components).
Restriction: Some types of armor have a restriction rating and an appropriate black market purchase DC modifier. Remember to apply this modifier to the purchase DC when making a Wealth check to acquire the armor on the black market.
ALUMISTEEL ARMOR (PL 5)
This easy-to-acquire alloy is lightweight and reasonably strong. Bioreplica robots and liquid-state robots cannot have integrated aluminsteel armor.
Equipment Bonus: +5.
Weight: One-quarter the weight of the robot's frame (rounded down).
Speed Penalty: -5 feet.
Purchase DC: 10 + one-half the base purchase DC of the robot's frame.
Restriction: None.
DURAPLASTIC ARMOR (PL 5)
Duraplastic armor is made of advanced plastic polymers, like carbon fiber and high-grade fiberglass. Although relatively cheap and light, it doesn't offer tremendous protection. Bioreplica robots of Medium-size or smaller and liquid-state robots cannot have integrated duraplastic armor.
Equipment Bonus: +3.
Weight: One-eighth the weight of the robot's frame (rounded down).
Speed Penalty: None.
Purchase DC: 5 + one-half the base purchase DC of the robot's frame.
Restriction: None.
DURALLOY ARMOR (PL 6)
Duralloy armor is harder, heavier, and more durable than alumisteel. Bioreplica robots and liquid-state robots cannot have integrated duralloy armor.
Equipment Bonus: +8.
Weight: One-half the weight of the robot's frame (rounded down).
Speed Penalty: -10 feet.
Purchase DC: 10 + one-half the base purchase DC of the robot's frame.
Restriction: None.
RESILIUM ARMOR (PL 6)
Resilium is more malleable alloy than duralloy, although not as strong. Bioreplica robots of Medium-size or smaller and liquid-state robots cannot have integrated resilium armor.
Equipment Bonus: +6.
Weight: One-eighth the weight of the robot's frame (rounded down).
Speed Penalty: None.
Purchase DC: 5 + one-half the base purchase DC of the robot's frame.
Restriction: None.
CRYSTAL CARBON ARMOR (PL 7)
"Grown" in orbital laboratories, crystal carbon is a composite fiber material that outperforms neovulcanium (see below) on the battlefield. Bioreplica robots of Medium-size or smaller and liquid-state robots cannot have integrated crystal carbon armor.
Equipment Bonus: +8.
Weight: One-eighth the weight of the robot's frame (rounded down).
Speed Penalty: None.
Purchase DC: 15 + one-half the base purchase DC of the robot's frame.
Restriction: Licensed (+1).
NEOVULCANIUM ARMOR (PL 7)
Similar to duralloy, neovulcanium uses plasma-forging techniques to create an alloy of unparalleled resilience. Bioreplica robots and liquid-state robots cannot have integrated neovulcanium armor.
Equipment Bonus: +7.
Weight: One-quarter the weight of the robot's frame (rounded down).
Speed Penalty: -5 feet.
Purchase DC: 10 + one-half the base purchase DC of the robot's frame.
Restriction: None.
MEGATANIUM ARMOR (PL 8)
Sandwiched layers of crystal carbon and neovulcanium held in a magnetic matrix, megatanium represents the apex of robot armor. It is exceedingly hard and durable. Bioreplica robots and liquid-state robots cannot have integrated megatanium armor.
Equipment Bonus: +10.
Weight: One-quarter the weight of the robot's frame (rounded down).
Speed Penalty: -5 feet.
Purchase DC: 10 + one-half the base purchase DC of the robot's frame.
Restriction: Licensed (+1).
REACTIVE ARMOR (PL 8)
Consisting of layers of insulating gel or compressed gas between cerametal sheets, reactive armor provides the same protection as crystal carbon armor but is considerably cheaper and easier to produce. Biodroid robots, bioreplica robots, and liquid-state robots cannot have integrated reactive armor.
Equipment Bonus: +8.
Weight: One-quarter the weight of the robot's frame (rounded down).
Speed Penalty: -5 feet.
Purchase DC: 5 + one-half the base purchase DC of the robot's frame.
Restriction: None.
