Class 1 lasers are plenty bright. I would actually say that MORE laser pointers are Class 1 than Class 2, because Class 1 is generally considered "eye-safe" (or at least, as "eye-safe" as a laser can get!).


That being said... Take an old stage trick, and use a flashlight with a mask on it so that it only shows light where you want it. Use a powerful flashlight, powered by the robot's main battery, maybe use a filter to color the light, and cut a mask (or a barn-door system of panels) to get the light to fall exactly where you want it.
