Team Vision for Integrated System Build & Test Phase

During this phase our team planned to assemble the entire system and have it working independent of the monitor, keyboard, and mouse. Additionally, the packaging would be completed. Upon the completion of these items, testing to the engineering requirements would begin. In reality, the team spent the majority of the phase integrating the system and awaiting the arrival of crucial components. This left little time for testing the system so some of the planned testing will occur in the final phase.

Test Results Summary

System Weight

Our complete packaging with all components assembled was weighed to be 181 g. This equates to just under 6.4 ounces which satisfies our maximum 9 ounce requirement.

Packaging Stress Analysis

A static stress analysis was completed using Creo Simulate to determine how our packaging made of PLA material will react to compressive loads. It was found that with a constrained bottom, the packaging was able to withstand up to 250lbf of compression on the top, right, and back sides simultaneously while not exceeding the flexural yield strength of 145 MPa at any point.

Force Sensor Calibration

In order to obtain a weight output from the force sensors, our test subject (Nick) wore a shoe with a sensor embedded in the sole while standing on a scale, so voltage output from the sensor and weight from the scale could be compared. This data was used to create a linear trend between weight applied and voltage output. This equation was used to get a weight output directly from the force sensor. Then, the test procedure was repeated to confirm that the weight output from the force sensor and from the scale were consistent.

Risk Management Snapshot: 10/30/19

While most risks became less likely, the chances of the system not functioning properly have increased due to recent discoveries regarding the Juicebox Zero and Decawave API.

Plans for next phase

Team goals The goals for the final phase include testing on the system, implementing feedback, and completing the paper and project. The bulk of the work needed to be done is testing to engineering requirements and optimizing the system to customer desires. Individual Responsibilities to Achieve Team Goals
