  1. Group 11- ASME Design CompetitionFinal Design Review • Alicia Christie • Desmond Bourgeois • Toddrick Ruff

  2. Topics Covered • Overview of Competition • Designs Selected • Expandable Body • Free-Body Diagram Calculations • Rock Collector with Actuators • Three-Wheel Design with Actuators • Lifting Box to Clear Barrier

  3. Overview of Design Competition • Optimize Score • Weight • Power used (mAh) • Time • Accuracy • Follow Competition Rules • Size (14.5 x 6.5 x 6.5 in) Schematic of Test Course

  4. Decision from Last Presentations 3 – Wheel Design Rock Collector Mechatronics, Ariel University Center

  5. Expandable Body y Locks when fully extended Body needs to extend by 4.34 in: (2 x y) = 4.34, with overlap and distance

  6. Free Body Diagram- Vehicle Climbing Barrier

  7. Rock Collector Axel “False” Floor

  8. Rock Collector Actuation(Doors)

  9. Rock Collector Actuation(Rock Ejection)

  10. 3 Wheel Operating Principle(Recap) Outer axel Assembled View Inner axel

  11. 3 Wheel Actuation

  12. Rock Collector Lifting Fixture • Problem • Creating space for the Rock Collector to pass over objects

  13. Solutions • Pulley System or Gearing System • Use actuators or motors to raise height of Rock Collector • Drawbacks • Weight, Spacing, Interference with other components • Modify a Transmission for the use of one motor for two functions • Drawbacks • Code, Weight, Spacing, Intrinsic mechanics

  14. Hinge Design • Passive Method • Operates by utilizing the robot’s forward motion

  15. Prototype Procedure
