Signal filtering reduces interference, while a finite state machine controls movement and helps the robot recover when signals become unreliable or obstacles are detected. Ultrasonic sensors, a gyroscope and ArUco visual markers provide additional navigation support.<\/p>\n\n\n\n<p>Experimental results showed a 100% success rate across 13 Bluetooth navigation trials, with an average navigation time of 143.4 seconds.
