Design a compact four-wheel chassis sized approximately 25–30 cm long and wide, with four 12V DC gear motors mounted on the sides driving four rail-compatible wheels, and include a flat lower base plate for the wheel system and motor mounts, followed by a second internal electronics plate and a top transparent or metal cover plate. Place the Raspberry Pi 4 centrally on the top plate with the camera module mounted at the front on a small elevated arm angled around 45° downward toward the tracks. Position the microcontroller board (ESP32/Arduino Mega) just below the Raspberry Pi on the middle plate, along with the motor drivers (L298N/BTS7960) near the motors for short wiring. Mount the 12V battery pack toward the rear for weight balance, and place two DC-DC buck converters beside it to supply regulated 5V to the Pi and sensors. Install four ultrasonic sensors: one on the front, one on each side, and one on the rear edge; place four IR sensors underneath close to the track surface for gap detection; mount the IMU at the geometric center of the chassis for accurate orientation readings; fix the vibration sensor on the motor mount region; place the gas sensor and temperature/humidity sensor on the top plate with open airflow; mount the GPS module on the highest point of the top plate for sky visibility; and position the LTE/communication module or USB dongle on a corner with its antenna oriented vertically. Add cable routing channels or clips along frame edges to keep wiring organized, LED status indicators near the front or top for visibility, and leave a removable top cover to allow easy access for maintenance.
