the robot continuously analyzes the average RGB value of the pixels in the camera image; if the blue component passes a certain threshold, the robot stops, fires its laser at the part of the world corresponding to the blue area

I note that if the the robot only looks at the blue RGB component, then it will end up firing its laser not just at blue things (low R, low G, high B), but also white things (high R, high G, high B), fuchsia things (high R, low G, high B), teal things (low R, high G, high B), and variants of said colors. "Blue-minimizing" is not even a correct description!
