Team Vision for Preliminary Detailed Design Phase

Summarize: During this phase, the team intended to continue to prove the feasibility of the intended design both electrically and mechanically and also to build a prototype in order to prove the intended bones and muscles will dynamically move in the intended way. The feasibility and prototyping that we accomplished in this phase raised many more questions and concerns which are detailed below, however this is the perfect time for those questions prior to the detailed design review and before we start building.

Goals for next phase:

Iterative activities to demonstrate feasibility, including assumptions you made in your analyses or simulations. Have you completed sufficient analysis to ensure that your design will satisfy requirements? Have you included all usage scenarios in your modeling?
