Team Status Report for October 18th

The most significant risk that could jeopardize the success of our project is the implementation of the embosser system. Most of our design is still theoretical, and we haven’t had the opportunity to test it yet. This component is critical to achieving our MVP, so failing to develop a functional embosser would halt all work. If our initial design does not work as intended, our plan to manage this risk is to modify our system to resemble an existing braille label embossing design.  The trade-offs would be slower outputs and this design takes up more space. However, this approach would ensure functionality.

As we finished our Design Report this week, we revised our embosser mechanism to ensure that our device can shift the label media while preserving previously printed text. This update involved integrating an additional motor. All of these changes were reflected in the Design Report. We hope to test this new design soon, and as previously mentioned, we have a backup plan in case this method fails to produce accurate results.

For the most part, our schedule remains the same, with the exception of our CAD design. This week, we hope to complete our CAD design of the embosser system and begin the prototyping and integration process.

A was written by Francesca, B was written by Abby and C was written by Bella.

Part A:  With regard to global factors, our design keeps in mind those who are blind or visually impaired. Beyond the simple fact that we are aiming to print in braille, which is targeted or those with visual impairment, we are taking further factors into account, such as the fact that tactile design will be absolutely critical in providing the device to audiences who cannot otherwise see. Our intention is to make the device as easily usable and accessible as possible– simple enough for children, older adults, and those not technologically savvy to understand. We intend to work with the Office of Disability Resources and the Western Pennsylvania School for Blind Children to ensure we achieve these goals.

Part B:  Our system is using the simplest conversion of letter to Braille character. For different languages, there exist different short-hands for commonly used words and phrases, but to keep the language accessibility as wide as possible, we will not be including this. In addition, we are using Unified English Braille which is currently being moved to be the universal set of Braille characters. One area where our design culturally falls short, is we are using our OCR to recognize the Latin alphabet. This could be addressed as a stretch goal, but realistically, our scanner will be able to recognize languages that use that alphabet.

Part C: There are several ways our project will be approached considering environmental factors. To reduce our environmental impact, we sourced components such as our microprocessor from within the department, which not only saves us money, but it also reduces transportation related emissions. Another way we are keeping the environment in mind, is by using recycled or biodegradable materials wherever possible for our prototypes. From a design perspective, we are aiming for low power consumption from our device.  Perhaps, by integrating a  sleep mode or another method to keep wasted power to a minimum. Additionally, our device will be powered by rechargeable batteries, rather than disposable ones and helping to lower long-term environmental waste.

Bella Woodard’s Status Report for October 18th

This week my work consisted of working on the Design Report. My contributions were the “Design Trade Studies”, “System Implementation”,  and “Project Management” sections.

My work isn’t necessarily behind, but I’m concerned that we might not be able to begin integration this week, which is our goal. The main reasons are possible delays in part arrivals and ongoing correspondence with the Office of Disabilities.

Next week I hope to build embossing head and frame prototype, as well as, purchase a battery pack and charging board to integrate with our microprocessor.

 

Bella Woodard’s Status Report for October 4th

This week we finalized our microprocessor choice, I helped complete our Design Review Presentation, and did the peer grading for other teams.

We’re a bit behind schedule. We had hoped to get CAD model done before our presentation, and I still need to order the camera and other hardware in order to begin integration. We’re also behind on contacting the Office of Disabilities and the Western Pennsylvania School for Blind Children, which we need to do soon.

Next week I plan to finish the CAD design in SolidWorks, complete the Design Report, order/request hardware components, and reach out to our stakeholders for feedback

Bella Woodard’s Status Report for September 27th

This week my contributions included:

  • Updating our Gantt to reflect current progress and adjusted timelines.
  • Meeting with our professor and TA to finalize design choices
  • Conducting research into OCR methods
  • Researching options for our devices battery
  • Researching mini keyboard implementation

meeting notes: https://docs.google.com/document/d/18jFJak_XMeZI0KY7Eypdu9q5hxDXurklSiYy3uhaF_I/edit?usp=sharing

Our progress for the design presentation is on schedule. However, I think we our behind in some research aspects. Specifically, in terms of outreach to members of the blind community.

Next week we hope to gather feedback from CMU’s office of disabilities and the Western Pennsylvania School for Blind Children, develop a SolidWorks model of the embossing mechanism, and update  our block diagram to reflect finalized components.

 

 

 

Bella Woodard’s Status Report for September 20th

This week I completed the project proposal slides and created the Gantt chart outlining our project timeline. Preparing these deliverables included collaborating with teammates, researching references, formatting the slides, and breaking down the project milestones into specific tasks and deadlines.

Project Proposal: https://docs.google.com/presentation/d/1WXwwa34O-rMQ0qtkz5L0SH64WpbvtYx2qES9lCsy7rg/edit?usp=sharing

Gant Chart: https://docs.google.com/spreadsheets/d/1xA4N9NPSlEUf5CPvli5-VonDIgC-3FK7PKDLm38_j1A/edit?usp=sharing

Our progress is on schedule, although there is still a significant amount of research to be done before we can begin the design process. Completing the proposal and Gantt chart has provided structure for the project, but additional background work will be necessary to ensure the design phase goes smoothly.

Next week, we hope to reach out to the campus Office of Disability Resources and the Western Pennsylvania School for Blind Children to conduct further research. In addition, we plan to complete our design presentation, incorporating insights gained from these discussions.
