Lego Mindstorms + Lasers 122

Time Required — Approximately 2 hours of tinkering. Having an Alpha Rex with a Laser — Priceless!' Of course, the usual warnings about voiding warranties and avoiding lasers apply."

That being said, the last point there is a strong argument against the infinite multiverse theory, as it is entirely possible that the probablility of the first post not involving sharks is exactly equal to zero, and thus, could never happen in the multiverse. Perhaps another

No; as long as proper warnings are given, even dangerous items can still be sold in stores.
I refer you to http://vision.about.com/od/eyesafety/a/laserpointe reye.htm [about.com], an article that gives several sources showing that laser pointer can indeed damage a child's eye.

The REAL joke is you're not going to go blind from a few seconds of exposure to a laser pointer, but everyone is too freaked out by the word "laser" to use some common sense, or do a bit of research.
The laser pointers you buy in stores (especially the cheapie ones you can use to tease the dogs with) don't produce a beam that's focused enough or intense enough to cause damage in a few seconds ... " even a minute didn't cause any decrease in eye function. You're most likely going to have a red laser, which

I figured that there would be more use of a retrofitted laser on a lego mindstorms bot.
Perhaps one could create a bot that would be able to launch projectiles while moving and be able to acquire targets using its laser pointing device.
Who knows... someone can always find a use for this mod.

Not so. The green lasers he mentions are often capable of casting beams that are visible without using smoke under low light conditions. Google "green laser pointers."

My first thought on reading that was "wow, somebody built a laser rangefinder for Lego Mindstorms". No such luck.
Biggest problem with amateur robotics is crappy sensors and lack of feedback. It's getting better, especially in Japan, but slowly.
