Team Vision for Problem Definition Phase

Since the problem definition for this project hasn't changed, the main plan for the group was to build on the definition based on where the last team finished their work and come to a consensus on what we felt was a reasonable summary of the work that lays ahead of us. In addition, the team went over the project goals and key deliverables to put forth an action plan. From this action plan and the information in the PRP the team then developed the list of customer and engineering requirements.

Project Summary

The Doc B Racing Real-time Telemetry System is an end-to-end system for data acquisition in the vehicle environment. The system will use a host of sensors and an onboard processor to log useful vehicle data metrics during a street or track driving event. This data is then made available to the user for review on a laptop or mobile device with intent to aid in vehicle setup, driver performance, and general maintenance.

Use Cases

Below is the use cases diagram. The first use case describes the setup routine for the operator, or pit crew member, for placing the device in the car and setting up the calibration. The second and third use cases are for during and after the race, depending on how the data wants to be displayed and analyzed.

Use Case for operator setup and calibration.

Use Case for driver saving data on SD card.

Use Case for driver sending data over Wi-Fi and saving on SD card.

Project Goals and Key Deliverables

The main project goals are to complete a marketable product that has the ability to acquire data from the car and integrate with the customers needs. Also, to build on the previous team's work and finish embedded system and sensor integration. Some additional Key Deleverables would be to participate in Imagine RIT in the spring, finish a poster and technical paper, and test in race car under real race conditions.

Customer Requirements (Needs)

A working document can be found here

Engineering Requirements (Metrics & Specifications)

Purpose

Create a contract between the engineer and the customer where indisputable satisfaction of the engineering requirements equates to customer satisfaction

Constraints

Unit size for car implementation.

Sale Price cannot exceed $1000.

Current budget for development is $500

Factors, usually system-level, that limit your design space (e.g., cost, total weight, total footprint, total power available). Are your constraints measurable and testable, and can they be traced back to customer requirements? Have you considered economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability constraints and engineering standards, for example?

Design Review Materials

Include links to:

Presentation

It is appropriate for you to send your customer and guide a link to this page in preparation for the review. This will ensure that they know what you will be presenting and how to view all of your work. Any EDGE link should start with http://edge.rit.edu/edge/P1xxxx..... Using "http" instead of "https" will ensure that non-RIT stakeholders can view the content without being prompted for a DCE login and password.

Plans for next phase

Begin to gather ideas to design wire harnesses, create a new enclosure for the microprocessor or find an optimal place in a car for it, fix code bottlenecking, make a more user friendly UI system, and make the data able to be gathered by either Bluetooth or Wi-Fi. These goals will be completed by the team working together and agreeing on one design that will be the best solution for the current problems, with the least amount of risks involved.
