I am trying to solve a warehouse difficulty we have been having involving stocking product with our forklifts. I need a laser that can be attached to the outside of a forklift arm, and transmit a horizontal distance back up to a screen near the operator, either via a Raspberry Pi or simply direct to an LED screen. Preferably, it would work as a wireless device, to eliminate the problem of wiring. Does anyone know of anything that might fit my needs? I don't need anything very sensitive, but it needs to measure about four feet.
