BN3101: Biomedical Engineering Design on Robotic Colonoscopy (Mentored by Dr. Ren)

Project Objective :

Magnetically actuated origami robots or motion generator mechanisms towards robotic colonoscopy

Schedule & Tutorials

wk1: Background and clinical descriptions

wk2: Intellectual Property

– Present the rough idea of your design concepts

– Do patent search

Follow up actions:

  1. Search for the most relevant patents for your projects
  2. Generate keywords using these patents pertaining to your projects
  3. Generate a list of User specifications for your device using this list of related patents. Hint: look for the various features of patented devices, and appreciate the intention of these features
  4. Create a table to compare the patented devices’ features


– You may search patents from www.google.com/patents or www.uspto.gov

– How to tell if a patent has expired? It turns out not obvious and please refer to the following readings: Brown & Michaels – “How To Determine Patent Term” USPTO:Patent Term Calculator (Beta Version) 

wk3: Design Methodology and Design Analysis

Tutorial Agenda (with tutors):
Follow the Design Methodology Slides and briefly identify:
– Role of each team member
– Procedure
– Project Plan Schedule
– Rough Needs‐Metrics Matrix

wk4: Project pitching with respective supervisors and CELC staff

wk5: Conference on presentation skills with CELC staff (2h)

wk6: Risk Analysis, Design Rationale and Verification

Tutorial Agenda:
– Follow up with week-2 action items and progress update
– Follow up with Design Rationale, Design Verification, and Risk Analysis
– Failure Mode, Cause of Failure, and Harms associated with your products

Risk Analysis Table[.docx]

wk7: Mid-term Review

Dr. Ren: Demo by Groups
– An extended/refined/polished/justified wrap-ups for the work done in the past weeks, including introduction/background/clinical needs/markets/significance/SOA/gaps-to-fill; IP, design methodology/design analysis/rationale/verification; risk analysis; regulatory; prototyping;envisioned procedures/system etc.

wk11: CELC Workshop on Oral Presentation Skills (2h) & Final Dry Run with Project Supervisors (1h)

(Notes from CELC) In Week 11, your CELC Tutor will meet you to discuss Oral Presentation Skills. Please watch the three videos which are listed under Week 11 in LumiNUS before you come to class on Tuesday 29 Oct.

In Week 12, your project team will have the opportunity to deliver a “dry run” of your final presentation with just your CELC tutor present. This will be a great opportunity to practice all your skills and get feedback on your presentation before you deliver it in Week 13.

wk12: Presentation practice with CELC staff (2h) & NO meetings with Dr. Ren 

  • Free Day for Team to Fix any problem with the prototype

wk13: Final Oral Presentation of Project

  • The final presentation (will be recorded) is on Nov 12, 4-6pm, in your preallocated room. 
    The respective CELC faculty would also be present. 
    Each group may have 15-18 minutes to present, 5 minutes for showcasing their product and 10 minutes for QnA (total about 30mts/gp).
    The final report may be submitted till 17th Nov.
    Again, for the report, please focus on the quality (eg, Figures/Tables), instead of the number of words/pages (please note we set an upper limit of words/pages, but not lower boundary, meaning QUALITY is the most important factor than anything else)

wk14: Submit prototype, reports and final project documents to project supervisor

Please submit soft copy of your report & project data and actual prototype to your respective supervisor. That is:
  • Physically: submit project prototype (including tools borrowed, make also sure the prototype is functional at the time of your submission.) to Dr. Ren
  • AND Electronically: (dropbox/Google-drive or whatever means and by group preferred) submit to Dr. Ren your group-project development documents including:
    • reports in .docx format
    • project presentation files (mid-term, ASTM and final) in .pptx or equivalents (please make sure the video is playable in another PC if applicable);
    • CAD design files (in solidworks or equivalents)
    • if applicable, source codes and a readme file on how to run the code
    • other key project data (e.g., verification experiment data collected in .xlxs), references, patents cited, and reference papers, etc.
  • The individual report shall have maximum 5 pages or 3000 words based (Tentatively, please follow the announcements later) on the template. With justifications, you may keep main critical content within 10 pages and refer other non-critical contents, such as references as appendix or google-drive/dropbox documents.
  • Team report template (excerpted and FYI only) All in one templateZip of the sample team reports
