Seed Dispesing Mechanism for Automated Gardening Robot

I created a robust and simple solution allowing the robot to drop seeds into the holes drilled by the robot. This design was created in order to let the robot differentiate the type of seeds that it would plant without needing to be refilled.
It is made to work with a simple pulsed voltage source to allow for low maintenance and intuitive software design.
The screws used were also modular and hot-swappable allowing the user to choose the screw needed for each size of seed in the chamber.
