Robots are enemies in the Crash Bandicoot series.
Robots first appear in Crash Bandicoot, where they are first seen at the Cortex power plant, with two varations; one probe that would hover over various areas; and another probe that would hover over toxic waste with spikes on it that would act as a hazard while jumping.
There is only one robot in this game, and it only appears in Level 21, Gone Tomorrow, and it is a large robot that will shoot three missiles at you and can only be defeated by a shot from the Fruit Bazooka, and a direct spin attack to the back when it turns around. Or it can easily be avoided by simply leaping, or slide-jumping around it. However, it is not 100% safe to do, and is very useful in the time trial for Gone Tomorrow. Only 4 of these robots appear in the game, and they are all on the same level. There is one that appears on the Green Gem Path. It fires four missiles instead of just three.
There are many variations of robots in this game, mostly found in space station levels; a yellow robot that would float around in random areas, another yellow robot that would go back and forth playing a piano-looking object, it has electricity on its head, leaving jumping on it out of the question, a blue robot that's head would go up and spin, and they hold no malice to you, a blue-rocket like robot that would explode if Crash came too close.
