Piano grass (Themeda arguens), reputed to have been introduced to Jamaica as packing material in an imported piano1 . There are about 27 varieties of this highly invasive grass/weed worldwide[1] and in Jamaica the species previously identified as Themeda arguens is of concern as it has progressively taken over lawns, pastures and roadsides [1]. The grass is of particular concern to livestock farmers due to its highly invasive and aggressive nature and the concomitant negative effect on livestock productivity, especially during its annual seeding period (November/December – April) [2], when the palatability of the grass diminishes significantly and the seed awns can cause severe damage to the mouth when consumed, and feet of livestock [2], sometimes requiring veterinary intervention.

At the inception of automated solar tracking in the 1970’s, geometric architectures with pair(/s) of solid-state photo-sensitive devices were constructed and used to detect the sun’s position. As an alternative in recent years, cameras have been used to capture and process live sky images to detect the sun’s position. When the sky is cloudy however, both approaches are prone to errors and sometimes require human intervention which tend to reduce the trackers’ economic viability [1].
