Queensland University of Technology Science and Engineering Faculty EGB 210 Fundamentals of Mechanical Design Warman Project Specification Version 1.0, 6 March 2017 1. Introduction You will use the 12-step Design Process (Karsnitz 2013) to solve the 2017 Warman Student Design and Build Project. You may refer to the latest version of the Warman Competition Rules 2017 in Blackboard for more details. Steps in the design process 1. Define the problem 2. Brainstorming / problem solving techniques for devising potential solutions 3. Researching the problem and generating ideas 4. Identify criteria and specify constraints 5. Explore possibilities 6. Select a viable approach 7. Develop a design proposal 8. Make a model or prototype 9. Testing and evaluating 10. Refining 11. Creating/building/making 12. Documenting the design process and results The demonstration of each team's device will take place in Week 12. The device will be assessed based on a number of criteria provided in the CRA. The top ten devices from the Week 12 demonstration will compete in the Week 13 semi-final to determine the QUT representative for the National Warman Competition final. Grading of the project consists of the following components: 1. Device presentation and performance of the device: 40% 2. Project report: 60% Criteria for assessment of each of these two components are provided in the Appendices A and B. An additional bonus 5% of your overall project mark is available if you complete the Week 7 milestone (submission of the Step 7 "design proposal"). The total mark obtained for the project corresponds to 40% of the final mark for the EGB210 unit. Your individual mark may be reduced relative to the overall team mark if there is evidence that you have not engaged in the team process adequately, as detailed in Section 7. 12.

Problem statement The objective is to design, build and prove a "proof of concept" collection and delivery system in a laboratory environment that simulates conditions on the Gondwana mine site. For the "proof of concept" competition, points will be scored when your autonomous 'system' collects a mixture of two golf balls, two squash balls and two racquetball balls and when golf balls, representing valuable ore, are placed into one remote container and the other balls, representing waste, are placed in a second container, as quickly as possible and with the lightest 'system' possible. 4. Competition guidelines and rules See Warman 2017 Competition Rules. Check key elements like weight limits, time limits for setup and completion of the task, the formula, conditions for disqualification, materials allowed (Note for example, Lego Mindstrom cannot be used but Arduino is ok). 5. Safety Safety is an absolute priority. Remember, you must be inducted to access QUT laboratories, wear suitable clothes and safety gear, and follow instructions of QUT supervisors and staff at all times. If a lab supervisor or official decides that the device presents an unacceptable hazard (e.g. uses unsafe forms of energy or materials), it will not be allowed to operate. Check with the organisers if you are unsure. 2As part of your report you will need to provide a risk management plan for your device and its operation to ensure that hazards are mitigated and do not present danger to group members, officials or audience during testing or presentation. For example, compressed springs present projectile hazard, as do compressed gases. Eye damage might result and suitable precautions must be taken. Batteries and chemicals could present fire and explosion hazards and cause burns or poisonous gas inhalation. Other mechanical devices may present pinch points or sharp edges which could cause cutting or severing injuries. See Appendix C for a template and example of a Risk Management Plan which will need to be completed and submitted in your report appendix. A copy must also be provided to the organisers for evaluation prior to being allowed to operate your device on the test track. 6. Timeline for Semester 1 2017 Week 1 Introduction Week 2 Project Brief Week 3 Groups finalised Week 4 Regular, minuted team meetings begin and happen at least once per semester-week up to and including Week 13 (10 meetings minimum in total). Week 5 Individual problem solving task due (6-page PowerPoint summary of the first six stages of design process). Week 6 Warman track and balls available for student testing in Launchpad Week 7 Group "Design Proposal" bonus milestone submitted to Blackboard (milestone adds up to 5 percent to your overall project mark.) Week 8 Development Week 9 Development Week 10 Development Week 11 Development Week 12 Device presentation in tutorial sessions (2 group members min. give a presentation (eg. PowerPoint) on behalf of their group, 6 minutes max. presentation time). Device performance day (or days). Two group members only allowed to set-up and run the device. Best run of two counted. Semi-finalists selected by panel of judges nominated by the unit coordinator. Week 13 Warman semi-final day. National Warman final representative group selected by panel of judges nominated by the unit coordinator. Project report submission (all groups). 7. Working in groups This project assesses your ability to effectively work in a group. You may allocate yourself to a group using Blackboard Groups within the timeframe announced on Blackboard Announcements. The maximum group size is six (6) students. The number of groups is limited, so full groups are necessary. Students who have not allocated themselves to a group by the designated deadline will be randomly assigned to incomplete groups. Small groups will be merged into larger ones where possible. 7.1 Group contribution correction factor The method for ensuring adequate student participation in groups is as follows. There is a 3minimum of 10 formal minuted meetings necessary as part of your project documentation (to be provided in your report appendix). The minutes will indicate attendance and participation by each individual (see Appendix D for suggested template). Your group will also be required to submit a group meeting attendance summary for all group members in the report appendix (see template in Table 1). Attendance and participation at group meetings is a vital sign of commitment to the group's objective. Subject to group approval, electronic attendance via Skype, for example, would be acceptable where it might otherwise be impossible for the student to attend. Every effort should be made to find a time that is convenient for all members. Only under exceptional circumstances should the group make any concession for lack of participation by an individual. Any concessions shall be acknowledged in the individual's Group Contribution Statement (Section 7.2) in the report appendix. For each individual, the group mark will be scaled by a "contribution factor" obtained as follows: ≥8 meetings attended 100% 7 meetings attended 80% 6 meetings attended 70% 5 meetings attended 60% 4 meetings attended 50% 0-3 meetings attended 0% Table 1. Attendance and contribution submission template (example) Group Number Surname Name Student Number Meetings attended Multiplication Factor (Calculated) 10 Surname 1 Name 1 ******** 10 1 10 Surname 2 Name 2 ******** 10 1 10 Surname 3 Name 3 ******** 10 1 10 Surname 4 Name 4 ******** 6 0.7 10 Surname 5 Name 5 ******** 8 1 10 Surname 6 Name 6 ******** 4 0.5 7.2 Team member group contribution statement A Team Member Contribution Statement is required from each student in the report, detailing in about 200 words the contribution made to the entire project. 8. Clarifications and queries Together with your group members, read the Warman Rules 2017 thoroughly to try and answer any query yourselves. If you remain not satisfied, you may direct the question to your tutor in the first instance. If the tutor does not know the answer, or does not provide one in a reasonably short timeframe, then you may contact the unit coordinator, Dr Dennis De Pellegrin. If the unit coordinator feels that he cannot answer your query definitively, he will confer with the national organiser for clarification. Answers to questions will normally be posted on Blackboard Announcements (with discretion so as not to reveal significant technical details of the enquirer's design) for the benefit of all competitors. 4Appendix A: EGB210 Warman Student Project – Project Demonstration Assessment Criteria (PART 1; 40%) Grade 7 (≥85%) 6 (≥75%) 5 (≥65%) 4 (≥50%) 1-3 (<50%) Criteria 100 85 84 75 74 65 64 50 49 0 A) Team presentation (in Week 12 tutorial, min. two team members presenting, max 6 mins.)

Some factors to consider when compiling your project report • Identify critical factors in the project – This means that you thoroughly understand the task specification and the assessment criteria. • Research and develop your knowledge of useful mechanisms – Research devices and mechanisms that may be useful to solve the design problem, eg. cams, pendulums, levers, bearings, gears, pulleys, etc. • Develop your knowledge of materials and strength calculations – Research materials that are light and strong, cheap and readily available, use of adhesives, fasteners, lubrication etc. Use knowledge gained in your course to make simple strength calculations so that the device is reliable and light. • Apply creativity and design methodologies – Develop multiple solution candidates and critically evaluate them in terms of the design objectives, such as device performance and ease of manufacture/simplicity, while minimising cost. Use a decision matrix to justify your selection. • Drawing and engineering design – Produce detailed engineering drawings (preferably both assembly and detailed part drawings) using solid modelling software like Solidworks, consider the limitations of manufacturing techniques and tolerances. • Construction methodology – Decide on your budget (eg. ~$100 per group) and choose materials, parts and construction techniques to fit within your budget. Identify and obtain parts early to ensure that deadlines are met. Provide a cost summary of your final design and compare to your initial budget. • Model and prototype evaluation – Construct a model out of low cost materials (cardboard, wood, clay) to evaluate whether the design meets expectations (size, packaging, ease of setup). Refine your prototype until you are satisfied with performance. Re-iterate previous design steps to address any unforeseen shortcomings and improve performance. • Final design – Construct the final device using available tools and manufacturing methods. • Collate design information – Keep a diary, have group meetings and take notes to document group member attendance, the design process, group decisions and candidate solutions. Try to justify your choices based on factual data and engineering knowledge. Demonstrate good project management practices. Assign leadership roles. Plan ahead with a Gantt chart, assign tasks and responsibilities, monitor progress. Prepare contingency plans. Keep records that will help you in the compilation of a high quality report. • Reflect on performance after the demonstration of your device – Compare your design to others', reflect on what you learned after your demonstration and how you could have improved your execution of the design process and improved device performance. Project Report Guidelines In this project you will work in a group of 6 students. A high-quality detailed report is required. The format of your report shall include standard margins (2.54 cm), Arial (11pt) or Times New Roman (12pt) font, at 1.5-times line spacing. The page limit for your report is set at 40 A4 pages. Thirty pages is the recommended minimum. Typically, figures and tables shall not occupy more than a quarter of the page limit allowed. Table of Contents, Abstract, References and Appendix are additional to the page limit and are unrestricted (although the abstract is never more than a page). The report shall include an introduction, body and conclusion. The body shall address the topics itemised in the marking criteria. Additional drawings, data and calculations summarised or referenced in the body should be included in the appendix. The appendix information should not be essential to understanding the main body of your work, but provides evidence to the marker that you did the work correctly. Not following the recommended format, layout and page limit may result in a grade penalty depending on the level of transgression. Submission Guidelines A detailed, original, hardcopy report is required from each group. Each report will demonstrate that the work was conducted independently from other groups. It is up to the group members to distribute the project tasks evenly amongst themselves using sound project management principles. Each group member will receive the same group mark provided that sufficient attendance at group meetings is demonstrated, detailed in Section 7. A Team Member 7Contribution Statement is required from each student detailing in about 200 words the contribution made to the entire project. The name of each group member must be on the cover sheet of the project report, accompanied by each student's signature. Report submission deadline: The project is worth 40% of your EGB210 grade. The report is worth 60% of the project, while the demonstration is worth 40%. The project report is due in Week 13 of Semester 1, Wednesday 31 May 2017 via Blackboard/Assessment. Late submissions will receive zero marks. Therefore, allow plenty of time for editing, correcting, collating, signing by group members, etc. Criterion Reference Assessment You are expected to submit a formal design report which states your background, objectives, research, solution and conclusion. Headings include: a. Title b. Abstract c. Table of contents/list figures and tables d. Introduction e. …… f. …… g. Conclusion h. Appendices (including team member contribution statement) i. References The report assessment is broken into two parts broadly classified as: (A) Implementation; (B) Communication (see Report CRA above). (30 min. - 40 pages max.) 8Appendix C - Risk management plan The purpose of a risk management plan is to make you think ahead of an activity's occurrence to identify all hazards so that risk levels can be reduced as much as practically possible. You must consider all of the risks associated with the manufacturing and testing of your device. The completed risk assessment must be included in your report appendix. The editable Risk Management Plan file will be provided in the Warman folder in Blackboard. 9101112Appendix D – Group meeting minutes example/template (courtesy of Ben Armstrong) See Section 7 for details of group meetings and the importance of taking meeting minutes. 13
