+A crank equipped with a cyan wheel and a yellow low-density plastic arm undergoes continuous rotation. Its offset geometry drives the arm along a circular trajectory. A cyan backpack is connected at the distal end of the arm. As the crank rotates, the arm transmits motion, inducing jerky, intermittent forward translation of the backpack. The backpack slides subject to kinetic friction, its displacement strictly coupled to the crank's angular position. Each rotation cycle generates tension in the plastic arm, drawing the backpack forward prior to release. The mechanism maintains synchronous motion between the rotating wheel and the sliding load.

+The active crank, equipped with an orange wheel and a yellow low-density plastic arm, rotates to drive an eccentric journal. A rigid connecting rod links the journal to a red backpack. During crank rotation, the connecting rod transmits motion, inducing jerky and intermittent forward displacement of the backpack. Kinetic friction resists the sliding motion, while displacement remains strictly coupled to the crank's angular position. The yellow arm traverses the cycle, repeatedly pulling the connecting rod. Friction determines the sliding velocity, counteracting vibrational forces generated by the rotating wheel. Each revolution advances the backpack progressively, maintaining synchronization between the rotary driver and the sliding load.

+An active crank equipped with a red distressed wheel and a reddish-brown reflective arm rotates, driving an eccentric journal along a circular trajectory. A rigid rod connects this journal to a yellow-green backpack traversing the sand surface. Motion transmitted through the rod induces jerky, intermittent forward translation of the backpack. Kinetic frictional resistance is present during the backpack's sliding, and its displacement is strictly coupled with the crank's angular position.

+A crank equipped with pink matte wooden wheels and a gray rough arm rotates, causing its eccentric journal to traverse a circular trajectory. A rigid rod connects the journal to a gray matte backpack resting on the sandy surface. This rotation actuates the rod, propelling the backpack forward via abrupt, intermittent translational motion. Kinetic friction impedes sliding, ensuring the backpack's displacement remains strictly coupled to the crank's angular position.

+A crank featuring a gray brick-patterned disc and a mottled green matte arm rotates, driving an eccentric journal along a circular trajectory. A rigid rod connects the journal to a teal woven smooth-surface backpack. Rotational motion transmits force through the rigid rod, inducing discontinuous and intermittent forward translation. Dynamic resistance impedes the backpack's motion. Throughout the cycle, displacement remains strictly coupled to the crank's angular displacement progression.
