EGR 286ARD 3: Creativity and FunctionalitySPR 14

Objective: The teams will build a machine to accomplish some function.

Educational Goals: Experience in designing a simple machine, (including creativity, sketching, prototyping); interfacing motors and sensors with a microprocessor.

Requirements:

  1. The machine will fulfill a function determined by the team. It should be interesting and must function as advertised.
  2. The machine will incorporate at least two motors.
  3. A minimum of three sensors will be used in the machine
  4. A sensor must be activated to start the machine motion
  5. Some action of the machine must activate the remaining sensors, i.e. operator interaction will not do anything other than begin the process. Note: A light turning on to activate a light sensor does not meet this specification!
  6. A minimum of three LED light indicators will be used, each showing a different machine state.
  7. The machine will be built substantially from material provided in the class room.
  8. Extra motors and building material may be supplied by the team subject to instructor approval.
  9. Teams may pair together for the project but the motor, LED, and sensor requirements will be altered by the instructor.
  10. String may be used.

Deliverables:

Monday, April 21st: The teams will submit, in class, 15 well documented and neatly executed sketches of possible machine designs. A decision matrix used to choose the machine design and a well written backstory that creates the need for the machine will be submitted to Bb learn. Note: “create a good backstory” is not a viable criteria for the decision matrix. Incorporating this as a criteria will result in a 0 grade for the entire matrix!

Friday, April 25: The teams will prepare a memo describing the machine they intend to build. The memo will provide a good description of the design, the sensors used and contain at least one decision matrix, properly documented. (Proper documentation includes the description of each design choice, explanation of the criteria and scaling, a summary and justification for the rankings.) Sketches of the prototype will be included. The prototype must be constructed of cardboard or other suitable material.(A prototype is built to answer specific questions about the design. Several prototypes may be built to explore different aspects of the design. The memo should address this.) The memo will be submitted in class. The prototypes will not be returned to the teams.

Wednesday, April 30: Demonstration

The final report is due during the final exam time slot for each section. (Monday, May 5th, 10-12:00 for sec 3-4, and Wednesday May 7th, 10:-12:00 for sec 1-2).

Project Scoring Guideline
Deliverable / Project points (%) / Notes / Dates
Sketches, Backstory and decision matrix / 15% / 15 possible sketches, submitted as a team, a decision matrix to choose the machine, a backstory for the machine
Backstory and matrix submitted in Bb Learn, sketches submitted in class / Monday, April 21st
Prototypes / 35 / The memo describing the machine will be worth 15 points, the actual prototype will be worth 20 points – largely based on the class vote for creativity, workmanship and questions answered. The prototypes will not be returned to the team except for crucial parts that may be incorporated into the final machine (motors, electronics, etc.) / Friday, April 25th
Demonstration / 30 / Does it work? Are all requirements met? / Wednesday, April 30th
Report / 25 / Detailed requirements will be provided. A flowchart, CAD and a materials list/build plan will be required / On the day of the final exam

Prototype Rubric:

The prototypes will be placed on the tables in room 119. Each team will have approximately 2 mutes to present the prototype to the class. The maximum score is 25 points.
