Detailed Description

The sampled proximity infrared sensors of the Khepera.

The sampled proximity infrared sensors of the Khepera. This version of the infrared proximity sensors is based on data sampled from the real robot. It is fast but only works with objects created using the Arena. This sensor applies noise if requested

In addition to all parameters defined by the parent class (KheperaSensor), this class also defines the following parameters:

• activeSensors: Which IR sensors of the robot are actually enabled. This is a string of exactly 8 elements. Each element can be either "0" or "1" to respectively disable/enable the corresponding proximity IR sensor. The first sensor is the one on the left side of the robot and the others follow clockwise (i.e. left, back, right, front)
• roundSamples: the file with samples for big round objects
• smallSamples: the file with samples for small round objects
• wallSamples: the file with samples for walls

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
