Automated Trashcan

This design uses a linkage mechanism with pivots to move the tray from the top of the container to the interior, where the trash is deposited. When the mechanism is actuated, the first arm begins rotating and lifts the tray away from the top surface. As the motion continues, the second arm guides the tray along a controlled curved path so that it moves forward and eventually tilts toward the opening of the trashcan. This allows the contents of the tray to fall safely into the container.

The motion of the system is not completed with a single rotation. Instead, each pivot contributes to the movement at different stages of the cycle, allowing the tray to first lift, then translate forward, and finally rotate to empty the trash. This sequence of motions is important because it prevents the trash from sliding off the tray too early and ensures that the contents are only released once the tray reaches the correct position inside the container. By coordinating the motion of multiple pivots, the mechanism provides a controlled and reliable way to move the tray while keeping the overall design simple and efficient.
