Idea #1Lever. Heavy one side light other.

IdeasIdea #2Light Sensor. Sorted by sensor values.Idea #4Shoot it.Heavy ones go farther than light.

Idea #3Bounce Test. Calculate the bounce of each.

This system will allow for us to have the marbles roll down a ramp and get released one at a time to go through other parts of the marble sorter.

Physical Idea and Concept Sketch

This idea allows us to separate the metal ball from the rest, the heavy ball will fall into a cup while the other lighter ball will travel down the ramp.

Physical Idea and Concept Sketch

This solution allows us to have the plastic ball to be separated from the metal and wood, but after testing we found that it is inefficient and does not always work.

Design Matrix

This design matrix has 4-best, and 1-worse. According to the design matrix, Idea 1 and Idea 2 are worth pursuing.

Our final design includes a lever and a light sensor. The lever will sort out the heavy marbles and the light sensor will sort the plastic marble from the wooden ball.

Final Design Solution

We had to modify our original teeder todder (idea 1) to make it more stable in order to do this we added an additional leg on the other side of it and fastened it to the base of our project.

Design Modification

Our final design starts with a lever that separates the heavy marbles from the little ones. Then a light sensor sorts the dark lite marbles from the light lite marbles.

Final Design

Final Design Drawing

This project was an interesting one. The most difficult part of the project would be the time constraint. It was a short amount of time to design, build and test a solution in 5 days. What we ended up having to do was a divide and conquer approach. One person builds, one draws, on does the presentation. That worked out well.
