The aim was to build a gamified marshmallow launcher that:

Tracks a mouth opening/closing

Tracks a person's x and y position using 2 servos and an ML algorithm

Reloads marshmallows using 1 servo

Launches a single marshmallow into the general area of the mouth using 2 DC motors

The project can be viewed as a human snack dispenser that trains humans to catch marshmallows with their mouths.
