The video game Deus Ex contains a wide variety of robotic units which can be extremely beneficial to the player, or a severe detriment, depending on the type and situation. Commonly robots are used strictly for security purposes, serving the role of "walking turrets". However, some specialized robots can be used for medical reasons and for recharging and repair. All robots in Deus Ex can be disabled by EMP Grenades, and can be infected by a nano-virus with Scrambler Grenades, which forces an enemy robot to attack its own allies for a period of time.

Weaponized Robots

Small Security Bots

Mainly for personal use, the small security bot comes in two variations, which are essentially (and mechanically) the same, although aesthetically different. Neither variation walks with 'legs' like larger bots, but run on wheels. They both have two small assault guns, firing the standard 7.62 × 51 mm NATO round, like other bots. Both are slow-moving, with limited AI, and are therefore used by small organizations or [...] groups. It is never made clear, through in-game fluff, by which company the two robots are made. However, it may be fair to assume that the two bots are made by Page industries, as it is later found out that the company dominates the robot market.

Page Bravo-3 Peacebringer

The Page Industries Bravo-3 Peacebringer, also known as the 'Walking Turret', or simply 'Security Bot,' is similar to the Delta-2, in that it is a bipedal security unit with radar sight and (fairly limited) AI, however it is significantly smaller, approximately six feet tall, less heavily armoured and much more agile. Its only weapon is its single assault gun, firing the same 7.62 × 51 mm NATO round but is mainly used for small operations or for supporting Delta-2 Peacebringers. Like all security robots, it cannot interact with an enemy, but can say set phrases: 'Scanning Area', 'Target Acquired' and 'Target Lost.' Unlike other robots, its phrases are spoken very quickly, and in a muffled tone, making it difficult to hear. The first robot encountered in the game is a Bravo-3 Peacebringer (not counting the training mission where a small secuity bot is found first).

Some Bravo-3s have flamethrowers on top of the machine gun.

Page Delta-2 Peacebringer

The Page Industries Delta-2 Peacebringer, also known as the 'Military Bot', is the largest, most powerful and most deadly Security Bot in the game. It fires the 7.62 × 51 mm NATO round, through two assault guns, and has two sets of rocket launchers. It has thicker armour than any other robot in the game. When on patrol, the robot walks a set route, stopping every 10 yards (approximately) to scan its surroundings for enemies, in which time it says 'Scanning Area' and swings its 'head', which contains its radar sight. Because of it size and capabilities, the Delta-2 is only used by the military and government organizations (hence the nickname 'Military Bot.) However, its size makes it slow moving, and therefore an easy target under most circumstances. Smaller Bravo-3 Peacebringers often support Delta-2 Peacebringers with their increased speed and maneuverability. Smaller organizations usually opt for the smaller and cheaper Bravo-3 Peacebringer.

Service Robots

Matsu-Gravas R-118 Repair Robot

Found in many industrial areas, in game text discloses that the R-118 is characteristic of all bots of Matsu-Gravas' M-G repair line, and is used for a variety of repair, maintenance, and construction tasks. The R-118 is also described as being equipped with a Kroya 'Searchlight 3' argon laser attached to its M-G IRL arm, Chiang optics and visual processing, a self-recharging bioelectric battery, wireless command control, and 16 GB of internal memory (for "a superior amount of task customization at an affordable price"). In addition, the R-118 adheres to Matsu-Gravus LITE standard adopted by most other robotics companies, which allows all such repair bots to act as mobile rechargers.

It is this last ability that is the only one of use to the player, as the R-118 is only used within the game for recharging Bioelectrical Energy (BE) used for powering augmentations. Also, as with the M-G 'Nightingale' Med Bot, the R-118 requires a sixty-second power-up interval after each recharge.

Matsu-Gravas GV-4 'Nightingale' Medical Robot

Found in clinics and the UNATCO base, the Medical Robot, or Med Bot for short, can heal up to 300 hit points around the body in a single use. They can also be used for installing nano-augmentations to the player, when an augmentation canister is provided. In game text reveals that the medical bot industry is monopolized by Page Industries, however, the Matsu-Gravas is the only type of Med Bot encountered in the game.

Spider Robots

Although Spider Robots, or 'Spider Bots' for short, walk on only six legs, they are obviously physically similar to a spider in many ways. They come in two sizes: the larger of the two being about as large as a military bot. Spider Bots have two uses. In large industrial areas, they are used for repairing electrical systems, by shooting bolts of electricity at malfunctioning electrical components. However, they can shoot these bolts of electricity at the player, causing damage and often death. The Big Spider Robots can see on the DeusEx only two times: first time on the OceanLab on the UC room (near the lift to the Computer); second time in Area 51 before entering on the Page Zone.

Cleaner Robots

Cleaner Robots are small agile robots that clean commercial areas. Standing about 1 foot tall, Cleaner Robots are vaguely boot shaped and serve little purpose aside from their aesthetic benefit to the office and industrial environments in which they are found. They do flee when the player approaches, however, presumably to avoid being stepped upon.
