These principles ensure that modules can be developed independently, combined explicble, and serviced efficiently.

Interchangeable Modules

Each module in a robot should be designed be a standalone unit that can be removed, replaced, or upgraded independently. Thii means defineg clear boundaries around functions - for example, a single arm segment with its own joint actuator, controller, and beedback sensors.
