This RFID sensor for Lego Mindstorms NXT comes with 2 RF (radio frequency) transponders. This sensor allows your Lego Mindstorms NXT robot to detect and recognize the transponder, thereby triggering the specific behavior that you have programmed. Each transponder is a specific identifier that the sensor recognizes.
This RFID sensor enhances the detection capabilities of your robot and then increases their autonomy.
The following video shows an example of usage of the RFID sensor:
The RFID sensor allows the reading of a 5 bytes ID when in contact with a transponder key (each transponder in the world has a unique identifier).
The RFID sensor for Lego Mindstorms NXT is programmable using NXT-G and RobotC.
