Once we have elicited the Autonomous Rover Requirements (Stakeholder and System) and agreed that the team accepts them as a good definition of the Stakeholder's needs, the Team then proceeds to find a solution that will fit the problem.
Activities - Phase 2
The activities below are defined and described in the Functional and Physical Architecture DP.
SR.3.1 - Document or update the Functional System Design
SR.3.2 - Make trade-offs of the System Functional Architecture
Achieving an optimal architecture for the Autonomous Rover requires that a number of trade studies be carried out to find and select a collection of interacting functional components. The studies shown below are by no means an exhaustive list of studies to perform, but provide a good idea of what those studies consist of.
Simultaneous Location and Mapping (SLAM)
Threat Detection and Assessment
Rover Controls and Indications
Android Tablet Interface
iOS Tablet Interface
SR.3.3 - Document or update the Physical System Design
SR.3.4 - Make trade-offs of the System Physical Architecture
The development of the Autonomous Rover requires multiple decisions to be made regarding its physical architecture and the selection of components upon which the Autonomous Rover will be articulated. The paragraphs below identify some of the more important trade studies the Systems Engineers and Designers need to consider in order to achieve an optimal solution. As for the Functional Architecture studies, the list below is by no means exhaustive. What other studies can you think of?
Autonomous Rover Cost
As stated in the Stakeholder Requirements, the Autonomous Rover price must be kept to $200USD or less. This does not include:
- the Android or iOS (Apple) Tablet
- the transport case;
- the field toolkit; or
- spare parts.
