User manual of the ground sensor extension made by AAI Canada, selling this sensor.

These are the Gerber files necessary to produce your own Ground Sensors extension for the e-Puck

These are the schematics of the e-Puck Ground Sensor module. It is a small PCB that fits inside the thin opening in the front of the e-Puck plastic body, and connects to the e-Puck using the Micromatch connector on the bottom side of the e-Puck circuit board. It includes 3 miniature IR sensors and a PIC18 microcontroller, and interfaces with the e-Puck's dsPIC through I2C.

Some uses of this board include following a line on the floor, or detecting the presence of the floor (in case the e-Puck fell off the table).
