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. 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.
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. Carrying a bomb will slow a robot to about half speed. After all robots in a wave are killed, the wave is completed, while if the bomb is transported to the hatch, the wave is lost.
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. You and your 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.

|Second stage||Health regeneration|
|Final stage||Full crits all the time|
Robots are all designed off of each of the mercenaries employed under Blutarch and Redmond Mann, excluding the Engineer, 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 number of Special Robots also exist, which each possess unique abilities belonging to unlockable weapons rather than the Stock weapons that most robots use and have a customized name. Each special robot also has the advantages and disadvantages of the original classes it is based off of, unless noted.

The Sentry Buster is the only robot not to resemble a class, as it is literally a bomb on legs. It is never predetermined to spawn during a wave, and only spawns if Engineer is doing significant damage with his Sentry Gun to the robot horde. Its arrival is announced by a theme, a HUD notification, and by the Administrator. If the team has multiple Engineers with Sentry Guns, a Sentry Buster can spawn for each problematic Sentry Gun.
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 at full health by a backstab unless the knife is fully upgraded. They sport significantly more health than other robots, but move at half-speed. 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.
Giant Robot versions exist of the Scout, Soldier, Pyro, Demoman, and Heavy. Multiple Giant Robots can occur in a single wave, either of the same class or not.

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, and cannot harm players. It does, however, carry a bomb.
