Rapid Assembly and Design Challenge (RAD)

Request for Proposal: Rapid Assembly and Design Challenge (RAD)

Introduction and Overview

The National Academy of Engineers (NAE) and the NYU Tandon School of Engineering are seeking proposals for prototypes that address any of the fourteen NAE Grand Challenges, which fall into four cross-cutting themes of Sustainability, Health, Security, and the Joy of Living.

Specifications

Those responding to this challenge are tasked with creating a physical prototype and sales pitch for their device. The prototype can be a new technology or an improvement to an existing technology.

Each project will have a purchasing allowance of $100.00 to be spent on components for the prototype. A TA mentor will be provided to help define the project scope, set tasks, and manage purchasing requests.

Each project must complete two benchmark assessments, A and B. Three milestone presentations will be made over the course of the semester. They should demonstrate steady progress over the 10 week duration of the project showing component testing and later prototype testing. The prototype must complete commissioning. Final submission and a final presentation will complete the project. Prototypes will be judged by professors at the end of the semester, and the best projects will be awarded a prize.

Drawings

Prototype designs must be rendered in computer aided design (CAD) software for Milestone presentations and Benchmarks A and B (Figure 7). Fusion 360 is the recommended software for this course, which may be downloaded for free using an NYU email address. Other CAD software, such as SolidWorks, Inventor, and Rhino are permitted, but EG1004 does not provide resources in obtaining or learning those programs. All designs must show four views of the device: front, top, most detailed side, and isometric. Sensors and motors must be included in each drawing.

Each revision of the design must be documented and all changes must be presented during Milestone presentations.

Figure 7: Example of CAD Drawing

Diagrams

The circuit that powers and operates a prototype must be presented as a circuit diagram and a schematic diagram for milestones and benchmarks. A circuit diagram is a representation of the circuit, showing the physical layout of the wires and how the components are organized (Figure 8).

Figure 8: Circuit Diagram Example

A schematic diagram shows the plans and functions of the circuit, but not the physical layout of the wires (Figure 9).

Figure 9: Schematic Diagram Example

EG1004 recommends the circuitry modeling software Tinkercad and Fritzing to fulfill these deliverables. Tinkercad is a free browser-based circuitry software that is especially useful for constructing circuit diagrams with common electrical components. For projects with more complex electrical components, Fritzing is a free circuitry software with a library of electrical components that is useful for constructing circuit diagrams and schematic diagrams. For a guide on using both software, please refer to the Virtual Circuit Simulation Guide.

Remember to visibly label all components. In cases where the software does not support a specific component used within your design, use software like PowerPoint to amend your schematic.

Microsoft Project

A project schedule must be created in Microsoft Project. Learn to use Microsoft Project by accessing the Microsoft Project Student Guide. This schedule must include all tasks related to the project from the start of the project to Early or Final submission. Click here to access the guide on how to transfer a file. The Microsoft Project schedule should include:

• Minimum of 20 tasks, excluding Milestones
• Milestones should be clearly indicated on the project plan (duration of zero days)
• Each task must include the person responsible for completing the task (resource names)
• Use the "Copy Picture" function to include the schedule in the presentations. Do not take a screenshot
• Gantt chart must be displayed alongside the tasks list (fit onto one slide)
• Gantt chart must show a progress line
• Clearly state during the presentations whether the project is on-time, behind schedule, or ahead of schedule

For help planning the project, review the manual page Planning Project Scheduling & Costs.

Cost Estimate

A cost estimate must be generated that specifies the cost of all the materials and labor required for the design and construction of the prototype. The cost estimate must be presented in an Excel spreadsheet. Help in calculating the cost is available by reviewing How to plan the schedule and calculate costs for a project. Parts must be purchased from Amazon for ease of purchasing and faster delivery. Any adjustments or changes to the cost estimate over the semester must be documented and shown to the mentor.

The cost estimate should include the following:

• Labor cost breakdown with hours and rates. Labor is paid at $50/hr
• Cost of all materials and components
• Total cost must be shown in the bottom right corner

There should be no decimal places in the cost estimate as this is purely an estimate. Be sure to round appropriately.

Purchasing

The purchasing allowance for this 10-week project is $100.00. Materials are available in Open Lab, the MakerSpace, or upon request. All materials must be approved by an EG TA (such as the mentor, Open Lab TA, or Protolab TA). The list of materials available for all RAD projects is available here.

VEX materials are also available for use. The list of VEX materials and their associated costs is available here.

Use the following form for any purchases via Amazon. You must discuss this purchase with your mentor and get their approval before the product is purchased. All items in this list are prohibited and cannot be purchased.

• RAD Purchasing Form
• MakerSpace Purchasing Form

Make sure items are Prime eligible for faster delivery and the item must ship in less than seven days. Think ahead and order on time. Purchasing deadlines can be found on the section schedules and are as follows:

• September 30
• October 7
• October 15
• October 21
• October 28

Use the following forms for any purchases from the Makerspace including materials and advanced 3d prints. You must first go to the Protolab during operating hours and get it approved by the proto TA, then you can go ask the Makerspace TAs for your material.

• Advanced 3D Printing Request
• Material Purchase Request

For groups that require additional funding, the RAD Innovation Grant opens October 28 and is due by November 4. Groups can apply for more parts or for purchases that exceed their $100 purchasing allowance and must justify their purchase. There is no guarantee that such a purchase request will be approved, and so it is suggested that all necessary purchases be made as soon as possible.

Weekly Meetings

Team members must schedule and attend weekly meetings with the RAD mentor. A time slot for this meeting must be selected collectively and once set, that time slot must be unchanged for the remainder of the semester. The RAD mentor will set the benchmarks, extra credit tasks, and assist in research and technical tasks. For additional technical help, go to Open Lab and an Open Lab TA will provide assistance. RAD mentors will present information regarding the project, deadlines, and benchmarks. The presentations can be found below:

• RAD Meeting 1
• RAD Meeting 2
• RAD Meeting 3
• RAD Meeting 4
• RAD Meeting 5
• RAD Meeting 6
• RAD Meeting 7

CATME

When working on the project, peer evaluations and self-evaluations are critical for assessing how effective individual contributions are to the project. In the course, the recitation professor will use evaluations at each milestone using a software called the Comprehensive Assessment of Team Member Effectiveness (CATME). More information can be found on the Teamwork Expectations page.

Engineering Notebook

While working on this project, a record of all work done and all future plans and goals must be maintained in the Engineering Notebook. To complete benchmarks A or B, the Engineering Notebook must be shown to the Open Lab TA who is completing the assessment. For Milestone 1, Milestone 2, Milestone 3, and Final Submission, the Engineering Notebook must be approved by the Recitation Professor and be prepared to make it available to an Open Lab TA in a Word Document (DOC or DOCX) format. A guide to writing the notebook, an overview of the expectations, and how often the notebook should be updated can be found on the Keeping an Engineering Notebook page.

Extra Credit

RAD projects have multiple options for receiving extra credit.

• Extra credit tasks are determined by the mentor or professor based on the specific RAD project. The mentor will assign at least two tasks, with more if they want. Each task is worth 3 points, and a total of 6 points can be earned through extra credit regardless how many tasks are completed. If your group does not commission, then you will not receive any extra credit you would have otherwise received. Some examples may include:
  • Website integrated with product
  • App integration that provides additional functionality
  • Wireframe app design
  • Informational website
  • Soldering
• Completing Early Submission. Refer to the EG1004 Grading Policy for exact point values.

Milestones, Benchmarks, and Deliverables

As work on the project proceeds, three Milestone presentations will be made during recitation. All the items assigned in each Milestone are called Benchmark deliverables. These deliverables often consist of a combination of written submissions, presentations, and demonstrations. Additionally, certain benchmarks assigned by the mentor must be met, and reports/deliverables that add to the progress and comprehensiveness of the project must be submitted. The 3D Printing and Logo Guide page contains information on the 3D printing requirements and guidelines.
