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

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
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
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.
