One of the sensors I intend on integrating into my Mecanumbot is the 2D laser range finder from the Neato XV-11 robot. To make the connection between the laser and the computer cleaner, I decided to make a PCB. (My first PCB! Woohoo!) I followed the schematic from the Neato Laser guide on the ROS wiki. I later found out that there was one error in the schematic – the laser logic board needs 3.3V instead of 3V. Apparently the early versions of this laser were a little bit different. Or I’m wrong and I’m shortening the lifespan of my laser… Eh.
