ScopeWith a 5 person team, students should
design and build a working prototype that meets the specifications within the constraints.
Ideal Team- 2 Electrical Engineers 2 Mechanical Engineers 1 Industrial Engineer
FeasibilityFinancial – all of the major
components have been benchmarked for cost. Design is possible with the requested budget.
Time- Project Scoped to allow team to complete within Senior Design 1 & 2 especially if run on semesters.
Skill Constraints- Design feasible for team with requested skill set, electromechanical device requires some background in Controls.
