Control Logic and Command Flow
Autonomous
Ultrasonic + servo scan logic selects safest path in real time.
Command Flow
Measure distance -> Stop at <20cm -> Scan left/right -> Select safer route -> Drive
Manual
Keyboard commands map directly to directional motor control.
Command Flow
Capture key input -> Serialize command -> Send via Bluetooth -> Arduino decode -> Motor actuation
Voice
Speech-to-text intent commands control movement wirelessly.
Command Flow
Mic capture -> Speech recognition -> Map intent -> Bluetooth transmit -> Execute motion
Gesture
Hand landmarks are interpreted into directional commands.
Command Flow
Camera frame -> MediaPipe landmarks -> Classify gesture -> Send command -> Drive/stop
