ZOO Team Design Review November 8, 2007
Project Partner • Colombian Park Zoo here in Lafayette • Goals • Community Involvement • Educational Outreach • Conservation of Animals • Recently Reopened after Remodeling • Looking to EPICS to help Achieve Goals
How does EPICS help the Zoo? • Animal Enrichment • Primate Biscuit Feeder • Lynx Bumble Ball • Education and Entertainment • Animal Bingo • Zoo Kiosk • Fundraising • Donation Box
Primate Biscuit Dispenser Group Robert Klein – Senior, ME Zach Leeke – Freshman, MET Jenni Morsches – Freshman, FE
Primate Biscuit Dispenser Goals • Entertain Primate • Push Button Lights • Test Intelligence • Follow Sequences • Allow Observation • Allow Patrons to Watch • Give Rewards • Dispense Biscuits Food storage Primate Interaction/Circuit Dispenser Trough
Original Design • Rotary Motor Crank-Slider • Large Case Design • Little Space Optimization
Redesign Stage • Replace Motor with Linear Actuator • Less Jamming • Stronger • More Efficient use of Space • Replace 3/8” Plexiglass with ¼” Plexiglass • Still Strong yet much less Weight • Build Smaller, More Efficient Case • Redesign Primitive Electronics
Primate Interaction • Four Pushbutton Lights • Light Up in Random Sequences • Different Settings for Different Primates
Future Work • Design Microprocessor to run Lights and Motor • Construct Case • Build Motor Circuit • Test Motor with Biscuits
Questions About the Biscuit Feeder
Animal EnrichmentGroup Corey Lane – Junior, EE Joe Wootton – Junior, ANSC Kayla Frame – Junior, ANSC TeymourTahan – Sophomore, FE
Animal Background • Eurasian Lynx • Facts: • Found in forested areas of northern Europe & Asia. • Average weight of 25 to 75 pounds. • Feed mainly on roe deer, chamois, rabbits, birds and rodents. • Columbian Park Zoo is home to three Eurasian lynx: Koshka (pictured), Katya & Larisa.
Progress • Last semester’s conceptual design of a Lynx chaser track did not meet the Zoo’s criteria. • Our alternatives included the possibility of a vibrating ball or laser light track. • The zoo director recommended the vibrating ball for the lynx. • Same focus as original project, but different approach towards goal.
Models • Bumble Ball – Dogs • Boomer Ball – All animals • Wiggly Giggly – Equine
Model Materials • Hamster ball • PVC pipe • Epoxy • Batteries – 9 volt • Motor – Hsiang Neng, HN-GH12-1634T, 12 volt (min 4.5 volt)
Final Materials • Boomer Ball • Epoxy • Timing Circuit – 555 timer, power transistor • Lithium Battery – 11 volt, 2200 mAh, rechargeable • Motor – Hsiang Neng, HN-GH12-1634T, 4.5 – 12 volts, high torque/low RPM.
Budget • Total Budget: $150 • Epoxy: $5 • Hamster Ball: $4.50 • Bumble Ball: $14.50 • Boomer Ball: $55.50 • Battery & Charger: $50
Problems with Design Problem: Movement of ball is not as sporadic as desired. Possible Solution: Alternate stop and start of motor to continually change the center of mass of the ball. Problem: An inexpensive method to detect displacement of the ball to signal the motor to start. Possible Solution: A accelerometer which would be able to start and stop the motor.
Future Goals • Design Specific Internal Aspects. • Decide Appropriate Method for Stop/Start of Ball and Possible Displacement Sensor. • Design a Product which can be Easily Reproduced for Other Animals.
Questions About the Enrichment Ball
Animal Bingo Group Ryan Adams, Junior, **
Project Specification & Objective • The bingo game is designed for children from kindergarten through third grade. • The purpose is to educate children about the animals in a fun and exciting manner. • The project should be safe for children, and it should be transportable.
Game Play • Kalahari Desert in southern Africa. • The meerkat will use its tail to balance when standing vertical. • The meerkat's eyes always have black patches surrounding them; these act like an equivalent to sunglasses and allow the animal to see very clearly on bright days, even when looking directly at the sun • The meerkat has small, black, crescent shaped ears that have the ability to close when digging to prevent sand entering. • One or more meerkats will stand sentry (lookout) while other members are foraging or playing in order to warn them of approaching dangers.
Old LED Design • Breakage was occurring • Both sides of LED could easily touch each other • LEDs can be pushed out of position
New LED attachment • Wires clipped just below solder so there is no touching • Breakage does not occur • LEDs are secure and cannot pushed out of position
Future Work • Final game testing • Complete deliver checklist • Deliver project
Questions About Animal Bingo
Animal Kiosk Evan Kahrig, Sophomore, ECE Mike Gasser, Junior, EE Robert Klein, Senior, ME
Zoo Kiosk Goals • Provide Information to Zoo Patrons • Educate Guests on Zoo Animals • Allow Donations to Support Zoo
Specific Project Work • Zoo Kiosk • Rewrite code for Kiosk Program Software • Touch up Microcontroller Work for the Random Animal Noise Generator • Finalize a Product Manual and Troubleshooting Guide • Install Touch Screen Monitor • Minor Exterior Construction and Painting
Kiosk Software Features • General Information about the Zoo and the involvement of EPICS • Animals at the Zoo and Where to Find Them • Interactive Map of Zoo • Allow Zoo to add Announcements • Easily Updatable, Expandable, and User Friendly
Design Considerations • Large Buttons to Accommodate Touch Screen • Attractive interface • Expandable and Easily Updatable • Easily Portable to all Windows Systems • Code Easy to Maintain
Future Plans • Finish Construction on the Body • Finish Program Updates • Complete Microcontroller Work • Deliver Project to the Zoo

Interactive Donation Box Rupa Subramanian, Senior, IE Ryan Scheidt, Junior, EE Evan Kahrig, Sophomore, ECE Ryan Adams, Sophomore, ME
Description of Project Current donation box Zoo’s current donation box is not meeting their needs An updated model is desired Vehicle for zoo patrons to donate coins or dollars
Purpose of Project Provide the zoo with a unique solution to their current donation box scenario: More secure More attractive More modern Final Line: Encourage patrons to donate!
Possible Solutions Fix Old Donation Box Big Funnel “Plinko” Rectangular Box “Tree” Design Chosen Design: “Tree” Design
Brainstorming Alternatives Minimal constraints Keep options open Complexity issues Minimal coordination with Zoo Finalization hesitance
Project’s Design Alternative: Dome Design • Description of Design • Funnel • ‘Plinko’ system • Branches at top • Advantages: • Child-proof • Branch selection easier • Disadvantages: • Cost of Plexiglas • Optimal branch height • Difficult to construct • Dollar bills
Project’s Design Alternative: Bill Slot Design • Description of Design • No Dome • Added dollar bill slot • ‘Plinko’ system • Interactive electronics • Advantages: • All currency friendly • Incentive to donate bills • Branch height • Disadvantages: • Dollar bill integration • Child-proof branches • Technicality
Minor Design Detail Considerations Location of Money Box Number of branches Location of branches Mechatronics Options
