Presentation Transcript

  1. Rope Eater • Todd May, Monica Mulargia, Mason O’Lennick • Mechanical Engineering 101 • WSU: Vancouver • Fall 2007

  2. Outline • Introduction • Design • Experimentation • Construction • Performance Predictions / Reflection(s)

  3. Introduction • Purpose: Climb free hanging / secured rope without intervention • Course Material Application: Force, Friction, Power, Compound Geartrain, Mechanical Design • Real World Application: Unmanned exploration and robotics, etc.

  4. Design • Varying initial concepts; varying difficulties

  5. Design • Varying initial concepts; varying difficulties

  6. Design • Varying initial concepts; varying difficulties

  7. Experimentation • Paper turns into metal

  14. Performance Predictions • More contact area on drive wheel means better grip • Smaller drive wheel requires less torque • A rough estimate for the time it will take would be about 20 seconds

  15. Reflections • We changed our design to have more rope to drive wheel contact • We used aluminum because it was light and strong • Hardest part for us was getting a drive wheel • Over all we spent about $35 on materials • In the future we would implement lighter building materials
