Project Proposal

Description

The proposal outlines your project's motivation, design, requirements, ethics, and safety. The project proposal is an expansion on the information provided in the RFA. Use the following format:

  1. Introduction

    • Objective: One to two paragraphs detailing the problem statement and proposed solution.
    • Background: One to two paragraphs explaining the context of the problem to be solved by your project, including any relevent references to justify the existence and/or importance of the problem (i.e., the need or want for a solution).
    • High-level requirements list: A list of at most three quantitative characteristics that this project must exhibit in order to solve the problem. Each high-levl requirement must be stated in complete sentences and displayed as a bulleted list.
  2. Design
    • Block Diagram: A general block diagram of the design of your solution. Each block should be as modular as possible. In other words, they can be implemented independently and re-assembled later. The block diagram should be accompanied by a brief (1 paragraph) description of the high level design justifying that the design will satisfy the high-level requirements.
    • Physical Design (if applicable): A physical diagram of the project indicating things such as mechanical dimensions or placement of sensors and actuators. The physical diagram should also be accompanied by a brief one paragraph description.
    • Functional Overview: A brief description of the function of each block in the block diagram and explain how each block contributes to the overall design and feature list above. Include a discussion of the interface with other blocks. Every block in the block diagram must have its own description and each description should be 1-2 paragraphs in length.
    • Block Requirements: Include requirements for each block in the block diagram (requirements only, verification will be added for the Design Document). Please see the R&V page for instructions on how to write requirements. Every block must have a minimum of one requirement.
    • Risk Analysis: Identify the block or interface that poses the greatest risk to successful completion of the project. Justify your choice.
  3. Ethics and Safety
    Assess the ethical and safety issues relevant to your project. Consider both issues arising during the development of your project and those which could arise from the accidental or intentional misuse of your project. Specific ethical issues should be discussed in the context of the IEEE and/or ACM Code of Ethics. Cite, but do not copy the Codes. Explain how you will avoid ethical breaches. Cite and discuss relevant safety and regulatory standards as they apply to your project. Review state and federal regulations, industry standards, and campus policy. Identify potential safety concerns in your project.

Requirements and Grading

Please see the Proposal Grading Rubric for grading details. Please see Example Proposal for reference. Note that this proposal is an excellent example of what is expected of a proposal that would receive an "A" grade.

Submission and Deadlines

The Project Proposal document should be uploaded to My Project on PACE in PDF format before the deadline listed on the Calendar.

Sometimes bikers might not which gear is the optimal one to select. Bicycle changes gears by pulling or releasing a steel cable mechanically. We could potentially automate gear changing by hooking up a servo motor to the gear cable. We could calculate the optimal gear under current condition by using several sensors: two hall effect sensors, one sensing cadence from the paddle and the other one sensing the overall speed from the wheel, we could also use pressure sensors on the paddle to determine how hard the biker is paddling. With these sensors, it would be sufficient enough for use detect different terrains since the biker tend to go slower and pedal slower for uphill or go faster and pedal faster for downhill. With all these information from the sensors, we could definitely find out the optimal gear electronically. We plan to take care of the shifting of rear derailleur, if we have more time we may consider modifying the front as well.

Besides shifting automatically, we plan to add a manual mode to our project as well. With manual mode activated, the rider could override the automatic system and select the gear on its own.

We found out another group did electronic bicycle shifting in Spring 2016, but they didn't have a automatic function and didn't have the sensor set-up like ours. Commercially, both SRAM and SHIMANO have electronic shifting products, but these products integrate the servo motor inside the derailleurs, and they have a price tag over $1000. Only professionals or rich enthusiasts can have a hand on them. As our system could potentially serve as an add-on device to all bicycles with gears, it would be much cheaper.
