This project is designed to take the currently automated, manually operated pipetting system for reagent delivery employed by Oregon State's Fog Labs and turn it into an automated process. To do this, we have used a system of rail carriages to move an automated pipette around a working area, using printed circuit boards (PCBs), a touchscreen user interface, a platform to support, a pipette tip collection and disposal, as well as reagent wells, and a reagent reservoir with an acrylic housing to protect users from spills of harmful reagents. The main accomplishments were creating a fully automated dispensing process using an off-the-shelf pipette attached to a motor and creating a user interface program that allows selection of volume and wells to be filled with reagents. However, the main challenges included system integration across multiple team members' designs. And in terms of future improvements, we would spend more time collaborating, focus more on developing our printed circuit boards (PCBs), and choose less-volatile motor controllers.
