Senior Projects 2011 Eric Babski ~ Ben Gagne ~ Erik Artus Design Presentation 1

 Problem Statement  Solution  System Diagram  Sub-system Descriptions ◦ In-feed ◦ Feed Tube ◦ Sound Plate ◦ Catch Drawer ◦ Pneumatics  Schedule  Budget

 Our team was given the challenge to design a machine that improves the method of counting puzzle pieces for quality control.  The current method requires a human counting by hand piece by piece.  This is too time consuming, labor intensive and impractical.

We plan to use a combination of a pneumatics system and electronics to count pieces as they are loaded into the machine.  Air System  Microphone/Amplification  User Interface
