This project was an exercise in understanding basic mechanical systems by incorporating a cam, a crank, and a gear. We built a small structure out of paperboard, featuring an orca with a 100% human on its tongue. Each mechanism controls a different part: a gear moves the water inside the orca’s mouth to suggest the force of rolling waves; a crank drives the motion of the tail; and a cam moves the human back and forth, highlighting the difficulty of escaping. Through this setup, we were able to explore how simple mechanisms can work together to create expressive motion.
