1. A drive mechanism comprising:
a plurality of circular drive wheels rotationally coupled to each other, wherein two of the plurality of circular drive wheels include a drive pin,
a drive motor coupled to one of the plurality of circular drive wheels, wherein the drive motor is configured to continuously rotate the respective drive wheel, and consequently all other drive wheels,
a driven wheel having two outwardly opening radial slots arranged symmetrically on opposite sides of the driven wheel, wherein the driven wheel is configured to be driven into an intermittent rotation motion about its central axis by drive pins of the two of the plurality of circular drive wheels alternately engaging with one of the radial slots, wherein direction of the intermittent rotation motion alternates between two consecutive rotation phases,
a first gearing wheel uniaxially coupled to the driven wheel,
a second gearing wheel rotationally coupled to the first gearing wheel, and
a payload uniaxially coupled to the second gearing wheel,
wherein the second gearing wheel and the payload are configured to be rotated in a range of 160 to 200 degrees in a first direction during engagement of a first drive pin of a first drive wheel with one of the two outwardly opening radial slots.
