Team Vision for System-Level Design Phase

The plans for the systems design phase of the development process were to focus on generating potential ideas for the design and to better understand the requirements of the project so that we could select the best systems for our product development.

In the system design phase our team completed research on different methods of modeling the elbow, the anatomy of the arm, and structure alternatives to PASCO units. We also began to create system designs to lead to our planned designed proposal. This was done by designing a functional decomposition, re-visiting our bench-marking plans, refining our concept development plans, creating a morphological chart of potential system ideas, considering the feasibility of potential system solutions, and deciding on our concept selection choices.

The full status of the action plans for this phase is:

The anatomy of the system that was researched during this period is summarized below:

Plans for next phase

For the next review we plan on verifying and refining the prototype by standards and tests that we create. These standards will be developed from the re-visited risk assessment and solution plans we produce. Then we plan on developing and designing the plans for the joints of the arm. We hope to be able to answer the following questions: How do we plan on building the bones and joints? What are the largest risks for our selected systems? How will we verify our selected systems and prototypes?

Plans for next Phase

Plans for next Phase

The full project schedule can be found here: Project Plan Document P17082 The major points of the action items for this next planning sections are:
  1. Prototyping & Modeling, focusing on the bones, the joints, and the accurate ranges of human motion.
  2. Plan Updates, including the risks, risk responses, plan diagrams, and test plans.
  3. Subsystem checks and evaluations, focusing on the main subsystems of the project: the joints, the structure, and the motion systems
