Team Vision for Build & Test Prep Phase

Filling the Gap

This section describes design tasks that were completed at the start of MSD 2.

Engineering Requirements: Changes

In order to more fully prove that the customer requirements will be met, ER10 and ER11 were added to the engineering requirements. ER10 specifies a reliability for the connector mechanism. The requirement will the demonstration that the attachment between the RCS and Robofish should successful 97% of the time within 5 attempts. ER11 reflects a feasibility test that was conducted and will allow its accuracy to be proved.

Additionally, the wording of ER8 was adjusted to support a more feasible testing approach. The IP standards require calibrated equipment that is not available to us so an equivalent test will be performed in its place.

Subsystem Test Plans

The subsystem test plans will be utilized at the end of the subsystem build phase to ensure all subsystems perform as intended. These tests are not rigorous or conclusive, but are meant to act as a proof of concept before the integration stage commences.

Mechanical

Frame Assembly Check

Purpose: To confirm the integrity of the frame and ensure it will hold components as designed.

Electrical

RCS Side Circuit Test

Purpose: To demonstrate the RCS circuit performs all intended functions.

Robofish Side Circuit Test

Purpose: To demonstrate the Robofish circuit (From charging connector to buck converter) performs all intended functions.

Software

RCS Arduino Control Test

Purpose: To demonstrate that the RCS software to control Robofish attachment behaves as expected.

Risk and Problem Tracking

Issue Management: Waterproofing the Control Box

The control box that we inherited had several holes (large and small) cut through it. These holes compromise the water resistance of the control box and would cause us to not meet the engineering requirement for having a splash proof system. The following modifications will be made to waterproof the box:

Hole in Control Box, Plate covering hole
