Request for Proposal: Biomedical SLDP


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, Benchmarks, and Deliverables

As work is done on the project, three Milestone presentations will report on the project's progress. All of the items assigned in each phase of the project are called Benchmark deliverables. These deliverables often consist of a combination of written submissions, presentations, and demonstrations. Benchmark assessments evaluate the progress of the project.

Preliminary Design Investigation

The Preliminary Design Investigation (PDI) is extremely important, as it lays the groundwork for the project. It outlines the project idea, inspiration, and goals.

The PDI must include:

  • Cover Page
  • Project Overview
  • Goals & Objectives
  • Design & Approach
  • Cost Estimate
  • Project Schedule
  • Relevant Pictures

An example PDI template can be found here. The PDI is due by Benchmark A. Do not forget to include the items listed above. Use this link to access the VEX PDI Rubric.

Milestone 1

See How To Give a Milestone Presentation for the format of a Milestone presentation.

To submit, login to the EG1004 website using this special login information. Submitting with an NYU account or any other account will generate an error. Components may be resubmitted at any time before the deadline. Please note that submission times are based on the most recent submission.

Please note the deliverables for this project are as follows. If any of the following items are omitted, there will be a penalty. Be sure to click "Submit" at the bottom of the form and allow sufficient time for uploading. The following list includes deliverable items that are required:

Late Submission

Late submission is not allowed. If a project does not Commission or receive Partial Commission by the deadline set forth in the syllabus, the project will not be allowed to submit and will receive a 0 for the project grade. To receive Partial Commissioning, two TAs must evaluate the project and determine its degree of completion according to the Commissioning requirements and the project will be given a grade accordingly. Please refer to the EG1004 Grading Policy for more information.

Frequently Asked Questions

Can our robot climb up walls?

Yes, robots are allowed to climb up walls on this course.

If we go to the bomb using the hill route and then return to the start tile using the tunnel route (or vice versa), will we receive extra credit for completing both routes?

Yes.

Can we build some arm extension for our robot to disarm the bomb so that it does not have to reach the actual bomb tile?

No, arms are not allowed. On this course, your robot must actually get itself to the bomb tile and press the disarm button to receive credit.
