The purpose of this project is to give undergraduate students an idea of what it is like to be an engineer. Our team designed and created a 10-15 minute show to entertain 6-year-old audience using a variety of skills, such as but not limited to Solidworks, 3D printing, woodwork, programming, and circuitry. Each individual member created a computer-aided design (CAD) and 3D print a part that contributes to the final product.
Final paper available upon request.
Christmas Wonderland: About
Responsibilities: Create and program a penguin to sing “Jingle Bells”
Skills/Software: 3D Printing, Arduino, SolidWorks
Challenges: Designing the penguin based on the RC servo
Designed the penguin in half; used pegs to connect
Had to add a support for the servo to be placed on inside the penguin that is leveled to the mouth
Hot glued one end of the dowel on servo arm; used styrofoamas the beak and attached it to the other end of the dowel
Had to drill a vertical slot by the mouth area to allow the servo arm to translate up and down
Lessons learned:
Servos were not precise to control rotation
The movement of the mouth controlled by the servo was not precise as each loop had some slight differences in position; this made it difficult to exactly match the position of the mouth to the lyrics
