RFP*: Biomedical SLDP

* RFP is an acronym for Request For Proposal. Internationally, RFPs are called ITTs, an acronym for Invitation To Tender governmental agencies use RFPs to solicit new business.

Note: You should only use the materials contained in the Price list for Arduino Parts for Biomedical Projects. If you want to use other parts, get permission from your faculty member to do so, and also to determine the cost of the parts you want to use that are not in this price list.

Introduction and Overview

Biomedical engineering is a incredibly multidisciplinary STEM field that almost any engineer and CS student can enter into. It is the application of biology and engineering to make new and innovative devices to improve healthcare and medical options. Some of the most well known biomedical devices include artificial organs, prosthetic's, wearable's, and surgical robots.

Biomedical devices have already saved and improved the lives of countless people, your goal will be to develop one of these devices. Your group is being tasked with developing either a prosthetic or a wearable device that can improve the quality of life of the user. The prosthetic or wearable that you will develop will need to meet some basic requirements to be considered a working prototype.


Specifications

Your team must build a model of your design using the materials provided. A arduino program that will direct the devices sensors and/or movements must be created. A cost estimate of the devices components must be provided. All revisions to the original design must be recorded and explained. This includes technical design drawings, as well as cost estimates. All revisions to the arduino program must be recorded and explained.

The biomedical device must be able to complete a pre-selected series of tasks in a consistent and effective manner, and complete any of the extra credit tasks available. The biomedical device options can be selected from the list below.

The devices program may not be altered or switched during any part of its use. The device must be fully autonomous, and not altered or adjusted during testing. Please refer to the course syllabus for all due dates.

Device Choices

Prosthetic Option: Develop an artificial limb, a piece of technology that can be worn and effectively replace a lost body part, that fits under one of the following categories.

  • A prosthetic hand like feature that is able to wrap around a shopping bag handle and lift a 1 pound weight.
  • A prosthetic arm where an elbow like feature can move up and down (at least 90 degrees) and a wrist like feature can twist (at least 180 degrees), this arm must have a hand like feature but it does not need to be able to move.


Wearable Option: Develop an wearable device, a piece of technology that can be worn on the human body and provide valuable health or fitness information to the wearer, this is often assistive technology. that fits under one of the following categories.

  • A wearable device that can read the light intensity, pulse, or temperature, and have an output (diplay


Extra Tasks List

One of these tasks MUST be completed to complete the project, but all others can be done for extra credit. You get to decide which of these tasks you would like to complete.

  • Using more than one sensor
    • Each sensor much have an output that increases the quality of the device
  • Incorporating a display/touchscreen
  • Developing website or app
  • Use more than one machining type (3D printing, laser cutting, cnc)
  • Choose your own: Subject to project, meet with a radol, the rad ol will submit the extra credit idea to get approval


Model

You must build a scale model (1:1) of your design. The following materials will be provided in your kit or are available upon request:

  1. An arduino
  2. Temperature sensor
  3. Light sensor
  4. Humidity sensor
  5. Pressure sensor
  6. Mini servos
  7. Small display

The following miscellaneous materials are also available upon request:

  1. Buttons
  2. LEDs
  3. Wires
  4. Tape
  5. Glue
    1. Superglue
    2. Hotglue
  6. String
  7. Acrylic
  8. Wood
  9. Breadboard
  10. Prototyping board


Cost Estimate

Once a biomedical design is complete, a cost estimate must be generated that specifies the cost of all the materials and labor required for the construction of the design. Tabulate this cost information clearly in an Excel spreadsheet, using the materials cost list provided. Help in calculating the cost is available by reviewing How to plan the schedule and calculate costs for a project. The costs for the parts can be found on the Price list for Biomedical Project.

Create a cost estimate on a Microsoft Excel spreadsheet. The cost estimate should include the following:

  • Labor cost breakdown with hours and rates
  • Consolidate low-cost pieces: wires, tape, servos
  • Itemize high-cost pieces: arduino, sensors, PLA, acrylic, wood
  • No decimal places; this is an estimate after all. Round appropriately
  • Total cost must be shown in the bottom right corner

Milestones and Benchmarks

As you work on your project, you will be required to present periodic reports on your progress. We call these Milestones. All the items assigned in each Milestone are called deliverables. These deliverables often consist of a combination of written submissions, presentations, and demonstrations.

Milestone 1

Prepare a preliminary sketch of the design, a cost estimate, and an MS Project plan.

Look Ahead: What tasks are planned between now and Milestone 2?

    • Design approach
    • Mission statement
    • Preliminary CAD drawing of robot

    • This is your first design/ concept for what your device body will look like
    • Simple shapes and boxes do not count as an initial design
  • 1 working sensor with wiring completed & arduino code completed
    • The arduino code can display data with proper units
    • Your sensor will depend on which biomedical device you chose from "list of device choices"


Milestone 2

Using Lego Digital Designer, prepare four views of the latest design: front, top, most detailed side, and an isometric drawing. Also, create a drawing of the gear trains. Complete the latest Mindstorms program and the latest MS Project plan reflecting any schedule changes. Finally, calculate a revised cost estimate.

Early Acceptance

If you submit your project one academic week early, you are eligible for a bonus that will be added to your final semester-long project grade. You must submit all deliverables one academic week before the submission deadline (see syllabus for exact date). The deliverables received early are the ones you will use in your presentation. No adjustments to the deliverables submitted will be accepted.

Late Submission

Late submission is not allowed. If you do not commission or partial commission by the deadline set forth in the syllabus, you will not be allowed to submit and will receive a 0 for the project grade.
