High school students are making robotic fish feeders that help fish owners when they go away for the weekend or for vacation. This is a Tufts Center for Engineering Education and Outreach (CEEO) project that we use in the Teaching Engineering Education Program (TEEP) program that I adapted for high school studdents. For these projects, students are either using all LEGO or are combining LEGO and 3D printed, laser cut, or hand crafted parts. Many of the student fish feeders have 3D printed dispensers glued to a LEGO axle.
One my Engineering Design 2 students went a step further and made a very sophisticated custom LEGO piece a the hear of his fish feeder. He designed it in TinkerCad, sliced in Cura, and printed on an Ultimaker 2+ 3D printer.
