Detailed Description

The linear camera sensor of the e-puck.

This is a linear camera with configurable aperture (using the aperture parameter). The number of photoreceptors can be configured using the numReceptors parameter. Each receptor returns three values, one for each of the three colors (red, green, blue). This means that the size returned by this sensor is 3 * numReceptors. The inputs for the controller are returned in the following order: first the values of all the red receptors, then the values for all the green receptors, finally the values for all the blue receptors. This sensor only works with objects created using the Arena instance.

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

• numReceptors: the number of receptors of the sensor. Each receptor returns three values, one for each of the three colors (red, green, blue). This means that the size returned by this sensor is 3 * numReceptors (default is 8)
• aperture: the aperture of the camera in degrees. The real e-puck has a camera with an aperture of 36°, but here you can use any value up to 360°

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
