UNF ASME Material Sorter

Here is one of two teams from the University of North Florida competing in the ASME 2010 Student Design competition held at the University of Miami, Miami Florida (District F)

Problem statement: http://files.asme.org/asmeorg/Events/Contests/DesignContest/18197.pdf

This was built strictly for a competition with weight, dimension, and other requirements. Materials to be sorted also had strict dimensional limits.

UNF Team: Wendel Garcia, Ben Neese, Ellae Reyes, Duncan Wallace

and what if he gets a bottle that is heavier than glass...or an extremely lightweight glass material...

@za3eem11 we found a glass container with minimal dimensions and it still went through the door. For a heavy large tin containers, we tested it and none of them fell through. It was a matter of calibration and testing. You would be surprised as to how different the masses due to the densities and thickness required to make a usable glass container vs a typical tin container is. The door opened based on impact, which is based on momentum, therefore amplifying the difference in mass.

@okayDel5 Excellent job. I assume the tin sorter is called "spiny magnet thing". The person who designed that is a genius and deserves a medal or something - at least a plaque.

@za3eem11 What okayDel5 did not mention is that the contest specified a range of dimensions for each material. And based on the minimum size for the glass container (a small jar) and maximum size for the plastic bottle (approximately the size of a 20 oz bottle), the plastic would have to have at least a .25" wall while the glass would have to be super thin.

A real world sorter would have to sort by other means, but because of the specifications in the rules, you can sort based on weight.
