Rose Float Animation Design course sequence is structured to assist students in the design and construction of Rose Float with special focus on the design and development of mechanisms for animation. The weekly meetings will be structured similar to an industry design engineering review. A number of guest lectures on topics such as mechanism design, hydraulics, dynamics and vibration will be organized. Each session will include design review, Q/A, progress check and computer demo modeling followed by work at the Rose Float lab. Students will work in teams and closely interact with Rose Float committee members. At least one visit to a major float builder will be arranged during the course. The course will help student teams to establish engineering specifications, develop several concept designs, identify the optimum concept for implementation, create CAD models, perform engineering analysis, simulate mechanisms, create part drawings, build mechanisms and complete integration with the system. All activities are to be completed under strict deadlines.

Meeting Times
Saturday 9:00 AM - 1:00 PM
