  1. Egg Sucker 3000 Bryan Cole and Brendan Messier

  2. Background • ELM 4701 requires the class to complete a mini project in 6 to 8 weeks. • The project should demonstrate an understanding of mechanical engineering, electrical engineering, and programming software, and the ability to integrate all three.

  3. Problem Statement • Develop an automated system that can differentiate between eggs and rubber ducks, locate and retrieve all six eggs from a defined area, and place into an egg carton located adjacent to that area.

  4. Existing Tech • Industrial Egg sorting • Primarily use pneumatic lifting systems

  5. Solution Statement • An X/Y table using 12v DC motors and using ultrasonic sensors for positioning and locating eggs. • Pneumatics will be used to lift the egg, transfer, and drop the egg into the carton.

  7. Preliminary Solidworks model (in progress)

  8. Mechanical Overview • Motors will control acme rods that will move the “carriages” (one x and one y). • 80/20 aluminum for framing

  9. Mechanical Overview ctd. • Pneumatic vacuum pump will adhere to the eggs using a specially designed bellowed suction cup and hoist them

  10. Electrical Concept • FreescaleKinetix MCU • Sensors • 3x Ultrasonic position/distance sensors • 1x Pneumatic pressure (vacuum) sensor • Positioning • 3x 12v DC motors • Pneumatics • 60 psi vacuum pump • Pneumatic relay • Vacuum pump on/off

  11. Software Concept • C programming • States: • Search for egg • X Y grid pattern search • Height recognition (ultrasonic Z sensor) • Egg determination • Lookup table (egg vs duck) • Lift egg • Lower vacuum cup • Engage vacuum • Raise vacuum cup • Deposit in carton • Position over next open carton space • Lower egg • Release vacuum

  12. Work Breakdown
