railway inspection rover 3d model

Create a realistic 3D model of a compact 2×2 rectangular railway inspection rover with a metallic silver-grey body and black-yellow caution lines. The rover has four flanged steel train wheels fitting standard railway tracks, giving a sturdy industrial look. On top, include a tall, detailed pantograph with joints, springs, and insulator plate, a cylindrical 3D LiDAR at the front center, a 360° dome camera behind it, and GPS/Wi-Fi modules with antennas near the rear corners. The front face has two wide-angle cameras and triangular headlights, while the rear also has two cameras. At the bottom, place ultrasonic sensors on all four corners, LDS sensors near front wheels, two IR sensors on each side, an industrial downward-facing camera at the center, eddy current sensors on both sides, and a laser profilometer on the left side. Add wheel encoders and IMU near the center axis, dual motors near the rear wheels, and neat wiring channels under the chassis for a professional finish.
