Another type of robot is the Sentry Bot. These are large and powerful. In a post - apocalyptic battle zone, a Sentry Bot could be seen standing tall. It uses its advanced weaponry to fend off any threats. However, sometimes their programming can go haywire. There was a case where a Sentry Bot started shooting at friendly units because of a glitch in its targeting system. But overall, they are an important part of the Fallout world's mechanical ecosystem.
The Mister Handy robots in Fallout are also very interesting. They are designed to be helpful around the house or in some commercial areas. One Mister Handy was found in an abandoned diner. It still tried to serve customers even though there were none left. It would move around, cleaning the tables and preparing non - existent meals. Its little robotic arms flailing about in a rather comical way, adding a bit of charm to the desolate diner.
In the Fallout world, robots can be quite fascinating. There are Protectrons that are often seen guarding various facilities. For example, in an old vault, a Protectron might be the only remaining guardian. It has a simple yet effective programming. It patrols the corridors, its mechanical joints creaking slightly as it moves. If an intruder is detected, it warns them in its robotic voice, ready to defend the place it was programmed to protect.
