Our project focused on automating the application of seasonings in fast food. We created a linear zero-offset four-bar slider crank design that is driven by a motor. Before construction, we conducted various analyses to determine torque necessary to run the mechanism and limit potential mechanical failures. We determined that our mechanism would require a maximum torque of approximately 30 in-lb. We used aluminum T-slotted frames, aluminum bars, 3D printed parts, a motor, servo motor, raspberry pi controller, relay, and various fasteners to construct our mechanism. Our mechanism translated along the full slider path, although its motion was not as smooth as desired. Our salt dispersal mechanism functioned adequately and was able to control the flow of seasonings.
