Capstone Project (Marble Sorting)

For this Project we were tasked to sort five different marbles (wood, mettle, glass red, glass white and glass green ), with a total of 15 marbles. Through out the project their were options to gain extra points and or multipliers for doing tasks such as dropping all the marbles from a higher height or using pneumatic pistons. Our sorter sorted 5 wood marbles, 5 glass marbles, and 5 mettle marbles. We did not implement a color sorter for the glass marbles because we could not get it to work. Our sorter got through all 15 marbles successfully in under 15 seconds.


























To catch the marbles initially we used a section of cardboard box on its edge and cut a hole for the marbles to exit in the corner. The marbles were initially sorted by size, the glass were bigger than the wood and the metal. After that the wood and metal were sorted from each other by a fan witch pushed the lighter wood off the track and into a separate bin than the heavier metal. Each of the marbles dropped into a separate bin.

Achievements:

1) Organize it!

2) I've Made a Few Special Modifications...

    * Added a fan to push wooden marbles

    * Constructed a new hopper

    * Disassembled sorter and rebuilt it with many support improvements

3) Reflection

    + : Creative solutions, results fulfill problem statement

    - : Teamwork, only a couple of our members were constantly working (together)

    ? : Next time we need to improve our teamwork, and procrastinate less (and work on focus)

    ! : Why not have the entire class as one group and make them sort ten different kinds of marbles?

4) Process 15 marbles in less than 30 seconds. (6 to 10 seconds)

5) Marble Delivery

6) Drop marbles from 2 feet above machine

7) Used at least one motor
