3 Mechanical Overview 3

4 Project Description  Provide a product line of off-the-shelf motor modules and platforms for diverse applications  Scalable, modular, robust wheeled platform to carry payloads of 1kg mass  Module should be fully compatible with team P09204  Open architecture, Open source development  Target audience is educational and outreach programs 4

5 Customer Needs  Robust  Modular (High-tech Lego)  Infinite effective motion  High overall system efficiency  Open source and open architecture  Thorough Documentation 5

6 Design Rationale  Customer needs Identify what the customer really wants  Specifications Translate customer needs into engineering specifications  Concept generation Sketch approximately 20 concepts have the potential to meet customer needs and specifications  Concept selection Weight pros, cons, and risks of each concept  Detailed design 6

10 System Testing Plan  Drive System: Test drive system to ensure that it can move the module and payload.  Steer System: Test steer system to ensure that it can rotate the drive system under load.  Structure: Ensure structure remains in tact under normal conditions. 10

11 Cost Breakdown Prototype Cost (2 Motor Modules) Estimated Idler Cost (2 Idler Modules) $152.04 $395.70 Total: Lot of One Motor Module – $253.02 Lot of Ten Motor Modules – $1625.98 Lot of One Idler Modules – $118.84 Lot of Ten Idler Modules – $506.48 Mechanical Components for one robot: ~$481.21 Mechanical Components for ten robots: ~$4106.08 Electrical Cost Breakdown $700.00 Total: Mechanical and Electrical components for one robot ~$1181.21 Mechanical and Electrical components for ten robots ~$11106.08 11

12 High Risk Assessment  Risk: Drive/Steer systems fail their basic functions during testing. Drive system is unable to move the module and platform. Steer system is unable to rotate the drive module and steer vehicle.  Solution: Replace motors based on data collected during testing 12

13 Next Steps  Research motor wires  Order all parts  Test Plan – Formal Draft  Update all Documentation  Set up a Preliminary Construction Plan  Final Design by First Week of Spring Quarter 13
