Re: No lasers of any kind?

Are you absolutely sure that the robot in question used a laser? Many people see a small red light and assume laser, even though no coherent light is emitted. For instance, Many people assume that optical mice use lasers. They do not, only a red LED focused by a lens. Most optical encoders do not use lasers, but LEDs. It is very likely that what you saw was an LED.
