===Robot Companion Abilities===
Class Level
This is the character's Roboticist level.
HD
This is the total number of d10 Hit Dice the Robot Companion possesses, each of which gains a Constitution modifier, as normal (see Variable Construction). Robot Companions receive average HP per HD. For d10, the average is 5.5.
BAB
This is the Robot Companion's base attack bonus, which is equal to their HD. Robot Companions do not gain additional attacks using their natural weapons for a high base attack bonus.
Saves
These are the Robot Companion's base saving throw bonuses. A Robot Companion possesses two good saving throws and one bad saving throw, determined by the creature’s base form.
Skills
This lists the Robot Companion's total skills ranks. Robot Companions can assign skill ranks to any skill, but many skill require appropriate appendages that the Robot Companion might not have (including a voice, which is required for most uses of Charisma-based skills). Robot Companions can assign ranks to Artistry and Craft subskills, but they take a -10 penalty to checks made to make creative items such as abstract paintings or poems. A Robot Companion with a high Intelligence score receives bonus skill ranks per HD as normal. A Robot Companion can not have more ranks in a skill than it has HD. A Roboticist can reassign their Robot Companion's skill ranks when they spend 8 hours modifying it.
A Robot Companion's class skills are Acrobatics, Climb, Escape Artist, Fly, Knowledge (Engineering) Perception, Swim, and Use Device.
Feats
This list the total number of feats possessed by the Robot Companion. Robot Companions can select any feat that does not create a supernatural effect or require a biology.
Armor Bonus
Robot Companions get a bonus to their armor class as listed on Table 1 — Robot Companions. This bonus may be split between an armor bonus and a natural armor bonus, as decided by the Roboticist. This number is modified by the Robot Companion's base form and some options available through its Upgrade Pool. Robot Companions cannot wear armor of any kind (except for automaton plating, and only if the Robot Companion has the Plating Mounts upgrade).
Str/Dex Bonus
Add this modifier to the Robot Companions Strength and Dexterity scores, as determined by its base form. Some options available through the Robot Companion's Upgrade Pool might modify these scores.
Upgrade Pool
A Robot Companion has a number of Upgrade points as noted listed on Table 1 — Robot Companions. Points from this pool can be spent on a wide variety of modifications and additions that add new abilities, attacks, and powers to the Robot Companion. Whenever the Roboticist gains a level, the number in this pool increases and the Roboticist can spend these points to change the abilities of the Robot Companion. These choices are not set. The Roboticist can change them whenever they gain a level, or when they spend 8 hours modifying it.
Max Attacks
This indicates the maximum number of natural attacks that the Robot Companion is allowed to possess at the given level. If the Robot Companion is at its maximum, it cannot take Upgrades that grant additional natural attacks. This does not include attacks made with weapons.
Special
Robot Companions have the following special abilities, some of which are gained as the Roboticist levels up.
====Experimental AI (Ex)====
: Robot Companions use a cutting-edge form of artificial intelligence programming. This AI allows the Robot Companion a degree of independence other Automatons lack. Although it always obeys the Roboticist's orders, the Robot Companion has a simulated personality, and is capable of assessing situations, making decisions, and dynamically "learning," meaning its capabilities are not defined by programs. The Robot Companion has an Intelligence score, but is not truly intelligent. This allows it to gain feats and skill ranks, and behave in many ways as an Intelligent creature, but its limits become apparent under even cursory scrutiny; it does not have opinions or emotions (although it can pretend to with mixed efficacy), and certain concepts that truly Intelligent creatures might consider intuitive are novel or alien to it. The Robot Companion also begins play knowing all of its Roboticst's cultural languages, although this does not enable it to speak.
: Due to its experimental nature, this AI is unstable, and without consistent oversight and tinkering by the Roboticist, it may become volatile. For every day the Robot Companion spends away from its Roboticist, it takes a cumulative -1 penalty to its Intelligence score, slowly becoming more irrational and erratic until fail-safes kick in, shutting down automatically when its Intelligence reaches 2. The Roboticist can remove this penalty by spending one minute adjusting the Robot Companion's behavior processors.
====Variable Construction (Ex)====
: Unlike most Constructs, Robot Companions have Constitution scores. They still retain their Construct immunities, do not heal on their own, and are not considered living creatures. In addition, a Robot Companion is not destroyed at 0 HP. Instead, it is disabled. A disabled Robot Companion is helpless and cannot take actions except to move with half of its base, hover, or swim speed. A Robot Companion that reaches a negative HP total equal to its Constitution score is destroyed.
====Ability Score Increase (Ex)====
:Whenever the Robot Companion gains an increased ability score from increased HD (this occurs at the listed levels), the Roboticist selects which ability score is increased.
====Multiattack (Ex)====
:The Robot Companion gains Multiattack as a bonus feat if it has three or more natural attacks. If it does not have the requisite three or more natural attacks (or it is reduced to less than three attacks), the Robot Companion instead gains a second attack with one of its natural weapons at a -5 penalty. I the Robot Companion later gains three or more natural attacks, it loses this additional attack and instead gains Multiattack as a bonus feat.
==Robot Companion Base Forms==
Each Robot Companion has one of the following base forms, which determines its starting statistics. These base forms each possess a number of free upgrades. The bonuses from these upgrades are already factored into the starting statistics. Free upgrades can be suppressed or brought back (although not changed or removed) whenever the Robot Companion's upgrades are changed.
Robot Companions do not by default have base speeds, and a Robot Companion without any method to propel itself is helpless and cannot move.
Finally, a Medium base form can be made Small, giving it a +2 bonus to its Dexterity score, and a -2 penalty to its Strength score; a +1 size bonus to AC and attack rolls, a -1 penalty to its CMB and CMD; a +2 bonus to Fly skill checks and a +4 bonus to Stealth skill checks; and the damage of its attacks are deduced by one step. This choice can be undone or redone whenever the Robot Companion's upgrades are changed.

==Upgrades==
Each Robot Companion recieves a number of upgrade points that can be spent on a wide variety of modifications and additions that add new abilities, attacks, and powers to the Robot Companion. These abilities, called upgrades, can be changed whenever the Roboticist gains a new level or spends 8 hours modifying their Robot Companion. All upgrades are extraordinary abilities.
Some upgrades grant the Robot Companion additional natural attacks. All natural attack are made using the Robot Companion's full base attack bonus unless otherwise noted (such as in the case of secondary attacks). Robot Companions attacks add their Strength modifier to the damage roll, unless it is its only attack, in which case it adds 1.5 times its Strength modifier. If the Robot Companion only has a single natural attack, the attack is made using its full base attack bonus and it addds 1.5 times its Strength modifier regardless of the attack's type. When an upgrade that grants a natural attack references a free appendage, it means an appendage that is not currently being used for another natural attack.
Upgraes are grouped by their cost in upgrade points. Unless otherwise noted, each upgrade can only be selected once. Some upgrades are presented with suggested forms they take, but the flavor of any upgrade is determined by the Roboticist, as long as it is obviously technological.
===1-Point Upgrades===
====Cargo====
The Robot Companion has internal storage containers that allows it to carry items without arms. This storage space can hold about 2 cubic feet of material (1 cubic ft. if Small, 3 cubic ft. if Large, 4 cubic ft. if Huge).
====Climb====
The Robot Companion is equipped with hooks and special grips for climbing, giving it a climb speed equal to its base speed. This upgrade can only be selected if the Robot Companion has at least three limbs, but cannot be selected if it has the Treads or Wheels upgrades. This upgrade can be selected more than once. Each additional time it is selected, increase the Robot Companion's climb speed by 20 ft.
====Databank====
The Robot Companion gains the benefit of the Databank program. This upgrade can be selected more than once.
====Head====
The Robot Companion has a head. This allows the Robot Companion to emote, giving it a +1 bonus to Bluff, Diplomacy, and Intimidate skill checks (although this upgrade does not enable the Robot Companion to make such checks on its own). This upgrade can be selected more than once. Each additional time it is selected, the Robot Companion gains an additional head, but the bonus gained from having one does not increase.
====Improved Armor====
The Robot Companion's chassis is reinforced, giving it a +2 bonus to its armor bonus. This upgrade can be selected once for every five class level the Roboticist possesses (minimum 0).
====Improved Damage====
One of the Robot Companion's natural attacks is particularly deadly. Select one natural attack form and increase the damage die by one step. This upgrade can be selected more than once. Each additional time it is selected, it applies to a different natural attack form.
====Improved Equipment====
The Robot Companion's physical form is improved for one task, such as gaining specialized wings for directing flight, or powerful pistons in its leg to increase its jump. Pick one Strength, Dexterity, or Constitution based skill. The Robot Companion gains a +4 racial bonus to checks made with that skill. This upgrade can be selected more than once. Each additional time it is selected, it applies to a different skill.
====Invention Adapter====
The Robot Companion has an adapter to which its Roboticist can attach one invention of up to 1st level, allowing the Robot Companion to activate the invention. This is done as part of the Roboticist tinkering with their inventions, and the invention cannot be detached for the Roboticist's use until the next time they tinker with their inventions. For each additional upgrade point spent, the adapter can accept an invention of up to one level higher, to a maximum of 6th level. This upgrade can selected more than once.
====Layden Attacks====
The Robot Companion's attacks are enhanced with small but potent positive Layden fields, allowing them to count as magic for the purpose of overcoming damage reduction.
====Passenger====

The Robot Companion can broadcast any of the following: its own speech (if it can speak), what it currently sees and/or hears, and any text, image, audio, or video it has stored in a Databank. If the Robot Companion has a voice, it can play any audio signals it receives (a screen enables it to play video as well). This upgrade can be selected more than once. Each additional time it is selected, the Robot Companion's broadcast distance increases by 1 mile, and its signal strength increases by +5.
====Radio Scanner====
The Robot Companion has a scanner that automatically scans for radio signals. It automatically notices unencrypted signals when it enters their broadcast ranges. Whenever the Robot Companion enters the broadcast range of an encrypted radio signal, it is entitled to a passive Perception check opposed by the signal's encryption to notice it. Regardless of whether it fails or succeeds, it cannot make another passive Perception check to notice that signal for 24 hours (this does not prevent it from finding the signal by manually searching).
====Ranged Adapter====
The Robot Companion has an adapter for one ranged weapon, allowing it to hold, attack with, and reload the weapon. This upgrade does not grant the Robot Companion proficiency with any ranged weapons. If the Robot Companion has the Cargo upgrade, it can draw ammunition automatically from its storage even without arms. Fitting a ranged weapon to the adapter takes 1 minute of work. The adapter cannot be disarmed.
====Reach====
One of the Robot Companion's attacks is capable of stirking at foes at a distance. Pick one attack. The Robot Companion's reach with that attack increases by 5 ft.

This Upgrade can be selected more than once. Each additional time it is selected, it applies to a different energy type.
====Screen====
This gives the Robot Companion a screen somewhere on its body, which can be covered by or retracted into its chassis to keep safe during combat. The screen allows the Robot Companion to display video signals it receives through the Radio upgrade, or image, text, or video it has saved in a Databank.
====Slam====
The Robot Companion can deliver a devastating slam attack as a primary attack. The slam deals 1d8 points of damage (1d6 if Small, 2d6 if Large, and 2d8 if Huge). This attack occupies a free arm or leg, though a Robot Companion with no arms or legs can make a single slam attack using their entire body. This upgrade can be selected once for each free arm or leg the Robot Companion possesses (or once in total if it has no arms or leg).
====Swim====
The Robot Companion gains aquatic propellors, giving it a swim speed of 30 ft. This upgrade can be selected more than once. Each additional time it is selected, increase the Robot Companion's swim speed by 20 ft.
====Tentacle====
One of the Robot Companion's arms is replaced by an equally dextrous mechanical tentacle, granting it a secondary tentacle attack that deals 1d4 points of damage (1d3 if small, 1d6 if Large, 1d8 if Huge). This attack occupies a free arm, and this upgrade can be selected once for each free arm the Robot Companion possesses.
====Voice====
The Robot Companion gains an artificial voice. This enables the Robot Companion to speak, and to play any audio it recieves by radio or has stored in a Databank.
