Eyebots are spherical robots, slightly larger than the human head, with a loudspeaker and electrical zapper on the front and several long antennas protruding from its top and back.
Eyebots are hardly strong opponents, and the fact that they are friendly and will attack enemies that engage the player or other wastelanders, means that they are more beneficial than anything else.
The eyebot is armed with a zapper. It is extremely accurate with this weapon and will rarely miss, even over considerable distances. While not a very damaging opponent, the eyebot's mobility, small size and high accuracy can make it a threat if encountered by a low level courier. Fortunately, they are the most fragile robot in the game and can be easily destroyed. When killed, an eyebot will explode, causing minor damage to anything nearby.
The model for this eyebot is found inside the REPCONN headquarters building, just past the first few rooms of displays, however it is not operational. It is said to have advanced facial and voice recognition. It also differs to the other models in the way it actually has a screen, instead of a grille at the front (presumably to act as a television screen). It is accompanied by a prototype Mister Handy model, experimental protectron model, and a prototype variant of the sentry bot.
The following is based on Fallout: New Vegas cut content and has not been confirmed by canon sources.
Medical eyebots appear in the final confrontation with Ulysses, and will consistently heal the damage dealt to him by either the Courier or the Marked Men. After being destroyed, they will continually re-spawn unless the Courier manually shuts them off. Ulysses also mentions these were the machines responsible for his survival following the Divide's destruction, mistaking him for a member of the United States Armed Forces due to his jacket.
Repair eyebots appear in several nuclear silos spread out across The Divide, maintaining everything that needs to be repaired before eventual launches. After being destroyed, they will continually re-spawn unless the Courier manually shuts them off.
According to the REPCONN headquarters museum, the eyebots were originally intended as floating televisions before becoming surveillance and reconnaissance bots.
