  1. The Rube Goldberg Project-Operation Hamster Gate-Engineering 100University of Washington11/7/03 Team Members: Alex Georgescu Steve Lee Dan Miller Aaron Salzburn Amy Tice

  2. Outline • Introduction • Analysis • Top candidates & prototype design • Construction • Performance, failure and score • Conclusion and recommendations

  3. The Concept • Alex’s hamster was not being fed enough, so we decided to design a contraption that would facilitate his feeding process. We didn’t want him to get fat either so, he only gets food if he exercises. When his wheel starts moving it eventually opens a gate allowing him to get to his food.

  4. Agent Hamster • Code name: Mousey • Age: 4 months • Place of Birth: PetCo • Astrological sign: Cancer • Hobby: keeping in shape Loves long walks on the beach and discoing with the ladies! Get your groove on!

  5. Top candidates & prototype design • Our team members brain stormed together • Our original ideas were the ones we used in the project • We were going to have a robot in our plans but it was going to take too much time to build

  6. Run, Mousey, RUN! • The hamster starts running • His wheel is attached to a smaller wheel that starts turning • A marble falls on to a track and lands on a catapult. • KE->PE (gravitational)

  7. The Catapult • The marble falls on to the catapult • Its weight makes the catapult’s safety device fall onto a mousetrap • The mouse trap has a thread attached to it which sets of the catapult • The marble is launched into a funnel • PE->KE

  8. The Water Wheel • The marble falls into a funnel • It lands in a container that drops and pulls a cup down that starts pouring water • The wheel starts spinning • PE (g)->KE->PE (g)

  9. The Battery…. • As the water wheel starts spinning it makes a box knife cut a string • When the string breaks the two sensors of the digital Multimeter fall on the lemon creating a closed circuit • The tension in the circuit makes the digital screen change and that change is detected by the light sensor • KE->KE (m)->PE (g)-> closes a electrical circuit

  10. We Love Lego! • The change on the digital screen sets of the light sensor • Because the light sensor was set off the motor gets power for 10 seconds • The motor powers the conveyor belt which pushes off a weight • Chemical E ->Electrical E-> Light E-> Electrical E-> KE (m)

  11. Mmmm, mmm, Good! • The weight is connected to a pulley • The weight falls and tips the food container • Mousey has FOOD! • KE (m)->PE (g)-> KE (m)

  12. Performance, failure and score • Our project wasn’t completely tested out together because of the lemon battery still the individual parts were working fine • The lemon battery didn’t work as designed • The marble didn’t follow the designed path because the pieces weren’t stable enough

  13. Conclusion and Recommendations Overall it worked better than expected but with a few glitches • Recommendations: • Redesign the lemon battery • Make the pieces more stable so the marble doesn’t get stuck

  14. The Team! • This project required a lot of team work and careful planning. • We split up in groups and each smaller team worked on a different task. • We had some difficulties, but it all came together in the end.
