Just a short clip of my ED1 Mini Project. Task was to lift a half pound object. I designed the mechanics to look similiar to the Falkirk Canal Wheel in Scotland. I worked with two EE and one CE to create the machine in about 2.5 weeks. Achieved 2nd place out of 30 projects. The servo motor used is coded to rotate continuously unitl the IR sensor senses the tab on the wheel. Simple and sweet.
