I’m trying to design a robot combat game in which there are 2-4 teams of robots. The robots need to be able to identify each other as which teams they are on autonomously. The range would need to be at least a few feet. I wanted to mix with LIDAR so that the human controller can see what has been mapped and location of robots and their respective teams. Do you have a product that can assist me on this?

Hi Robert, the RFID Card Reader – USB does not have the range for the project you are describing. For a complex project design like this, I would suggest brainstorming with our Robotics community at forums.parallax.com.
