  1. P11211: Land Vehicle for Education: Chassis, Motor, Power Ryan Sutton: Project Manager / Mechanical Engineer Jonathan Fabian: Interface Manager / Electrical Engineer Jesse Keyser: Mechanical Engineer Matthew O’Neill: Mechanical Engineer

  2. Project Description • Robotic Platform designed to support student created attachments • Market: Freshmen Mechanical Engineers • Key customer needs and associated engineering specifications: • Mass Production Cost Less than $150/unit • Durable Able to withstand a drop of ≤ 3ft • Supports Student Creations Able to support ≤5lbs of additional weight • Easy to Operate Move at a speed of ≥ .5 MPH Turning radius ≤12in

  3. Design Concept Convenience Charging Port MSA Control Interface MSA Mounting Points Aesthetically Pleasing Façade

  4. System Architecture

  5. Product Development Process • Phase 1: Planning • Customer Needs • Engineering Specs • Phase 2: Concept Generation • Drivetrain/Power Supply • Shape/structure • Phase 3: Analysis • Torque requirement • Power requirement • Structural integrity • Phase 4: Final Design • Present detailed design • Order parts • Phase 5: Construction • Machining • Building • Phase 6: Testing • Confirm Engineering Specs • Phase 7: Steps Forward • Lighter robot will reduce cost

  6. Technical Risk Assessment

  7. Summary of Test Results

  8. Current Status of Project • Meets all customer needs • Meets all engineering specifications except: • Mass production cost • Drop test • All tasks completed on schedule

  9. Budget • Prototype Budget: $250.00 • Prototype Actual Cost: $204.21 • Mass Production Budget (Per 10): $150.00 • Mass Production Cost (Per 10): $170.33 • Alternative Design Potential Cost (Mass Production): $125.46

  10. MSD II Project Milestones • Week 2: Design finalized and parts ordered • Week 5: Functional chassis prototype • Week 6: Subsystem testing complete • Week 7: Functional system prototype • Week 8: Poster complete • Week 9: System testing complete, technical paper complete, Imagine RIT exhibit

  11. Future Work • Strive to cut down cost • Unibody construction • Weight reduction • Motor size reduction • Number of Parts reduction • Battery size reduction • Machining and assembly time reduction • Further develop P11211 alternative design suggestion • Further develop DPM rework
