Detailed Description

The ground sensor of the Khepera.

This sensors might be physically realized by monting an additional infrared sensors on the bottom side of the robot. Such sensor can approximately measure the grey level color of the ground. This sensor only works with objects in the Arena

The resources required by this Sensor are the same as those of the parent class plus:

• arena: the instance of the Arena object where the robot lives
