Safety

Low voltage/ Low current system will be fairly harmless to users.

Low power IR light is harmless. You can’t prove that RF signals are

harmful so HAH! Common sense.

Schedule

Risks

Unable to get parts. Price of adding feature is too expensive. Complexity of feature is too hard to

implement in a semester time frame. Scheduling issues.

Contingency Modular system eliminates need some

compatibility issues since we will have a communication protocol for between components.

Modular system we can drop a module without having to completely redesign our system.

If a system can’t be implemented to complexity we can remove that module for the time being.
