The robots are at our doorstep, men, and trust me – they are not going to be asking for a cup of sugar. No! These monsters are going to break down our doors, take our sugar, and sprinkle it on our graves! — The Soldier

Gray Mann's mechanical army. Pictured here from left to right are robot Demomen, Soldiers, Pyros, Medics, Heavies, Snipers, Scouts, and Spies.

Robots are the enemies fought in Mann vs. Machine, during missions. They were created by Gray Mann in order to destroy everything created by Mann Co.

Gameplay

Regular robots function nearly identically to the players, being operated by bots, whilst special robots exist that use non-Stock weapons, and other forms of robots exist with abilities and directives that no class normally possesses. Unlike players, robots can notably be sapped, temporarily disabling them often in groups, or in the case of giant robots, slowing them. As noted by Miss Pauling, they run on money, and they drop it when destroyed, allowing players to use that money to upgrade their weapons or buy a Power Up Canteen. Robots follow a set path to the bomb hole, marked by glowing blue arrows before each wave, though they may stray off that path if the bomb carrier is pushed away or to pursue a player. Robots will occasionally taunt after killing a player, and the bomb carrier will always taunt to receive its buff. Robots have an infinite supply of ammo, do not drop their weapons as pickups on death, and cannot collect health and ammo pickups. Robots also never randomly Crit, although some have a means of gaining the Critboost effect.

One robot per wave will enter the field armed with a bomb. The primary directive of the robots is to transport this bomb to the hatch at the end of the map, and the Defenders must stop them. After the bomb is dropped, another robot can pick it up. Any robot can carry the bomb, excluding the Sentry Buster and the Tank (although the Tank carries a separate bomb). Spies and Snipers won't actively try to pick up the bomb, but will if forced on to it via knockback. Carrying a bomb will slow a robot to about half speed, except Giant Robots. After all robots in a wave are killed, the wave is completed, while if the bomb is transported to the hatch and detonated, the wave is lost.

Robots have rudimentary behaviour. Their main objective is to either pick up the bomb and follow the preset path to the bomb hatch, or escort whichever robot is already doing so. On the whole, they do not take alternate routes to the bomb unless the sub-wave is programmed to flank, or the bomb has been dropped in a location off the main path. Robots generally do not care about destroying Dispensers and Teleporters if they are not in the way. They are also completely oblivious to cloaked and disguised Spies: they ignore flickering cloaks, collisions with "teammates", uncloaking noises, and possible Dead Ringers. They can detect if a nearby teammate has been backstabbed, but not with regularity. They do, however, always notice when a Spy is on fire.

Robots can be dispatched in groups known as "squads". One robot is designated as the leader of the squad, and the other robots in the group will follow and surround the leader. If the leader is killed, the rest of the group will scatter and act independently. Medic Robots automatically heal the leader of their squad and attempt to stay behind them, as opposed to other squadmates that tend to cluser in front.

Robots receive certain buffs after a period of time carrying the bomb, with new buffs stacking with the previous ones. A graphic on the HUD indicates which stage the bomb carrier is on and how long until it receives the next buff. Upon receiving a buff, the robot carrying the bomb will taunt with an accompanying sound cue, and surrounding robots will halt to wait for the carrier. The defending team can and should use this as a window of opportunity to kill the bomb carrier, especially if the robot is getting the third upgrade. These buffs will not occur if the bomb carrier is a Giant, though the HUD graphic shows a full meter.

Stages	Upgrades	Time Interval (Seconds)
First stage	Defensive buff, shared with all nearby robots	5
Second stage	45 health regenerated per second	15
Final stage	Full crits all the time	15

In each map there are areas, inaccessible to players, where the robots spawn and make their way into the playable area. While in this area, the robots are invulnerable (showing an ÜberCharge-like effect if attacked), immune to knockback, are unable to attack (although they may use their support items such as the Buff Banner), and the bomb carrier's meter will not charge.

Types

The standard robot set is designed off of each of the mercenaries employed under Blutarch and Redmond Mann and share their basic abilities. Regular robots are equipped with the stock loadout of the classes. Über Medics are not noted as regular robots, despite the fact that they use their Stock weapons.

A notification is always shown when a Spy enters the map, and its entrance is announced by the Administrator. Killing one results in being notified of how many Spies are left.	125

Variants

A number of variants based on the standard robots exist; their defining characteristics are based on other unlockable weapons rather than the signature Stock weapons. They are represented by a unique name and icon. Each special robot has the advantages and disadvantages of the original class it is based on, unless noted.

Giant Robots

Giant Robots are notably larger than other robots. They can only be slowed by a Sapper rather than destroyed by it, and they cannot be killed or even damaged by a backstab unless the knife is upgraded. They sport significantly more health than other robots, but move at half speed. Unlike regular robots, they are not slowed at all while carrying the bomb. Their presence in a wave is noted by a red background behind their class symbol in the pre-wave overhead. Giant Robots that carry the bomb do not receive buffs for it. All Giant Robots also have resistance to knock back.

Giant Robot versions exist of the Scout, Soldier, Pyro, Demoman, Medic, and Heavy. Multiple Giant Robots can occur in a single wave, either of the same class or not.

Sentry Buster

The Sentry Buster is literally a bomb on legs. It is never predetermined to spawn during a wave, and only spawns if an Engineer is doing significant damage with his Sentry Gun to the robot horde. Its arrival is announced by a ticking theme, a HUD notification, and an announcement from the Administrator. If the team has multiple Engineers with Sentry Guns, a Sentry Buster can spawn for each problematic Sentry Gun. An exploding Sentry Buster damages everything within range, including other robots. When it reaches a Sentry Gun, a sentry buster will crouch and begin to spin. During this short period, an Engineer can and should pick up his Sentry Gun and run away with it. The sentry buster will not pursue, and he can escape with his sentry intact.

Machine	Based on	Notes	Health
Sentry Buster	Demoman	Detects Sentry Guns that are dealing significant damage to the robot horde or has killed a certain number of robots and runs at the offending Sentry Gun, exploding two seconds after deploying. Cannot carry bombs like ordinary robots. Will always explode: either upon reaching the Sentry (even if the Engineer hauls it) or upon running out of health.	2500

Tank

Noted as "???" in the official Mann vs. Machine update page, the tank is a rare enemy that usually appears for one or two waves per mission, rarely more than once in one wave. It has a large amount of health, but no attack method (though it can kill players and other robots via crushing between walls or props while turning). It does, however, carry a bomb, and it cannot be stopped by any means other than its destruction. The final tank in every mission features black and white stripes.

Machine	Notes	Health
Tank	Extremely large amount of health. Deals no damage. Will deploy a bomb once at the bomb hatch.	Anywhere between 10000 and 60000 on official maps, based on the length of the path the tank must travel and its intended difficulty

Unused content

• RED versions of all of the robots (besides the Tank and Sentry Buster) can be found in the game files.
• There is an unused Gatebot helmet in the files, which resembles a Payload bomb with lights on the eyes, sides and on top. There are also three Gatebot lights specific to the Medic Robot. One adds a light to the chest and the back of the head, one adds a similar set of lights, but with more metal around them, and the other one adds two lights to the ear section of the head. The final Gatebot light also puts a light with a small cable hanging off of it, made to resemble a fez, on top of the head.

Bugs

• When a robot is forced to laugh from the Holiday Punch, the player can hear the laughter, but there is only an animation for the Engineer Robot. When laughing, they still have the ability to move, but cannot fire their weapons.
• When a robot taunts (ex: When a bomb carrier gets an Upgrade) despite what weapon they're using, they will always perform the Primary Weapon Slot taunt. Meaning if a Demoknight robot taunts, despite using the animation for the Grenade Launcher, if you are within range of the taunt, you will be taunt killed.
• Hitting a Sentry Buster with the Holiday Punch in the back will cause him to stand still for a few seconds and then explode. This can be used to prevent an Engineer from rebuilding/protecting his Sentry Gun.

Trivia

• Unlike the regular classes, who face the direction they're aiming and walk sideways or backwards, most robots are split across the waist so that their top half is facing the way they're aiming but their bottom half is facing the way they're moving.
• All robots have voice lines, robotic versions of the voice lines used by the class they are modeled on. All lack facial animations while doing so, save for the Heavy Robot, whose jaw moves up and down.
  • All voice lines added to the game before the Mann vs. Machine Update are available in robotic form, despite many of them being impossible to hear (e.g. lines relating to capping points or Payload carts).
• The Soldier, Demoman, and Sniper robots appear to use the regular human idle animations when they use melee, rather than the jittery idle animations used by the other robots.
• The programming for the Bomb is similar to that of the Intelligence, and the robots will perform responses based on this. The human players, however, have specific voice responses related to the bomb.
• Robots wearing robot hats (such as the Scout robot and Sniper robot) wear the RED version of their headgear. If set to equip the actual headgear (in these cases, Robot Running Man and Bolted Bushman respectively), they will have a bluer tint on their hats.
• Giant robots, with the exception of the Giant Medic, use different models with slightly skewed proportions (most notably a smaller head and larger torso) and more detail to make up for their larger size. The models themselves are the same size as the normal robots' but are scaled up 1.75X in-game. All hitboxes are the same for these gigantic robots despite these proportions.
  • They also have separate, more heavily-distorted voice lines, which are notably deeper and more mechanical-sounding than their human-sized counterparts. The Sniper, Spy, Engineer, and Medic robots, however, do not have these voice lines.
• Engineer Robots appeared in the game files since the Mann vs. Machine Update, but were initially unused by Valve until the Mecha Update.
