Abstract
A solar tracking system including a plurality of bases, a torque tube supported by the plurality of bases and configured to support a plurality of solar modules, and a drive device operably connected to the torque tube and arranged to translate the torque tube in a direction parallel to its longitudinal axis. The solar tracking system also includes a plurality of helical guides operably connected to the torque tube, and a plurality of cam assemblies, wherein upon linear movement of the torque tube, interaction between the helical guides and cam assemblies causes the torque tube to rotate about its linear axis.
