SUBSYSTEM INTERACTION
| Subsystem 1 | Subsystem 2 | Subsystem 3 | Subsystem 4 | Interaction Details |
|---|---|---|---|---|
| Spatial | Sensors co-located near facial visual displays. | Tracking sensors placed on articulating head/joints. | Touch sensors integrated directly into outer shell. | SS1 acts as the primary data gatherer, spatially mapped to all outputs. |
| Data | Sends user proximity/identity data to trigger emotion. | Sends coordinate data for joint target tracking. | Sends raw force data to validate physical contact. | Provides foundational input driving the other three subsystems. |
| Material | Shared internal wiring harnesses with displays. | Sensor cables designed to flex with mechanical joints. | Sensor pads bonded to the external protective casing. | Hardware requires flexible and protected routing. |
| Subsystem 2 | Subsystem 1 | Subsystem 3 | Subsystem 4 | Interaction Details |
| Spatial | Displays face the user by sensors | Displays move dynamically with head actuators | Positioned to remain visible during close physical contact. | SS2 translates states into visible/audible outputs. |
| Data | Recieves triggers | Sends emotional state to influence gesture speed. | Emits voice/light feedback based on safe touch | Outputs are coordinated with physical gestures and touch. |
| Material | Housed within the same primary head unit. | Sends emotional state to influence gesture speed. | Shared protective structural casing for safety. | Requires impact-resistant covers and secure mounts. |
| Subsystem 3 | Subsystem 1 | Subsystem 2 | Subsystem 4 | Interaction Details |
| Spatial | Repositions sensors for better field of view. | Directs emotional displays toward the user. | Actuators positioned directly behind touch panels. | SS3 provides the physical articulation required by all systems. |
| Data | Provides feedback on joint position to sensors. | Synchronizes arm/head position with LED states. | Adjusts stiffness based on physical resistance/force. | Mobility is strictly controlled by sensor and touch inputs. |
| Material | Metal frame supports rigid sensor mounts. | Provides structural support for emotion hardware. | Shock-absorbing mounts connect actuators to shell. | Load-bearing frame absorbs physical interactions. |
| Subsystem 4 | Subsystem 1 | Subsystem 2 | Subsystem 3 | Interaction Details |
| Spatial | Outer shell fully covers internal sensors. | Ergonomic shape invites friendly interaction. | Contact points located at the end of mechanical links. | SS4 represents the physical shell bridging robot and user. |
| Data | Triggers pressure touch detection events. | Touch patterns trigger positive emotional changes. | Imposes physical limits and resistance on movement. | Acts as the physical medium and barrier |
| Material | flexible materials placed over sensors. | Soft-touch plastics used for a friendly feel. | External casing protects internal actuators from damage. | Structures safely withstand force-based interactions. |
