Detailed Description

The linear camera sensor of the MarXbot.

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). You can decide whether to use all three colors or only part of them. This means that the size returned by this sensor is numReceptors * <num colors used>. 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. This sensor applies noise if requested

In addition to all parameters defined by the parent class (MarXbotSensor), 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), but you can decide to ignore some colors (see the "useRedChannel", "useGreenChannel" and "useBlueChannel" parameters). This means that the size returned by this sensor is numReceptors * <num colors used> (default is 8)
useRedChannel: whether the red component of the perceived objects should be used or not (default true)
useGreenChannel: whether the green component of the perceived objects should be used or not (default true)
useBlueChannel: whether the blue component of the perceived objects should be used or not (default true)
aperture: the aperture of the camera in degrees. The real MarXbot has an omnidirectional camera, so you can use here 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
