Team Vision for Build & Test Prep Phase

Plan to Accomplish

• Obtain a workspace for MSD II with compressed air for use with the cylinder.
• Order all parts required for testing
• Create test plans for the project
• Begin designing of web application
• Setup collector and raspberry pi on RIT network for testing

Accomplished

• Acquired work space with crucial components to our project, as well as storage for our materials.
• Ordered majority of materials, with remaining few being in the process of being ordered
• Laid out test plans across every necessary aspect of the project, by referencing the engineering requirements
• Began problem tracking on risks that have manifested into problems
• Began setup of collector and raspberry pi on RITs network
• Began machining of test bed components
• Began designing web application

Test Plan Summary

Requirements

We have narrowed our Customer and engineering requirements to fit the scope of our project. With our current budget and time constraints we believe that we forsee no issues with meeting our goal of having a working prototype by May.

Here are the current Customer and engineering requirements.

Testing Plans

Our project was broken down into various aspects based on what the engineering requirements were and testing plans for each aspect were broken down with a plan to accomplish each. Aspects such as battery life, max force, and data delay are planned out and prepared for testing. Each aspect will be broken down below, with a link to the entire testing document found here Goal: Make sure the database is able to retrieve data fast enough when it is under stress Goal: Make sure the database is able to insert data quick enough when it is under stress Goal: Make sure the Raspberry Pi will not drop ethernet packets when it is under stress from multiple collectors Goal: Test the range that the sensor can send to the collector Goal: Make sure the battery will last the desired time Goal: Make sure the piston is calibrated Goal: Verify that the accelerometer is reading the correct forces Goal: Verify the sensor is reading the correct forces at all forces and all angles

Final Test Prep Accomplishments

• Large majority of materials to be ordered have been ordered, with a small amount of items being ordered this week
• A team space has been reserved, and comes with compressed air to be used for testing

Risk and Problem Tracking

• Like all other phases of the project, the risks invovled are always changing and the list of them is being updated. A link to our most recent risk assessment can be found here.

• Some risks have became a reality and have manifested into problems, in which we actively work to solve these. A link to all problem tracking documents can be found here.
