The prompt
Create a parametric 3D CAD assembly of an automated solar panel cleaning robot frame. Main Chassis: A central rectangular aluminum block frame 400mm long, 250mm wide, and 30mm thick. The frame must span the horizontal width of a standard solar panel. Drive System (Both Ends): At both extreme longitudinal ends of the chassis frame, integrate dual-axis cylindrical wheel wells. Each well must include an integrated circular mounting plate (35mm diameter) designed to hold 12V DC geared drive motors, complete with 4mm screw holes for fixing the wheels. Cleaning Mechanism: In the center-bottom cavity of the chassis, design a dedicated parallel cylindrical cutout (60mm diameter) spanning the full 250mm width to house a rotating roller brush. At one end of this cutout, extrude an isolated cylindrical motor housing bracket to securely hold a dedicated secondary brush-rotation motor. Sensor Integration: Extrude a small forward-facing sensor bracket platform (40mm x 30mm x 15mm) on the front-leading edge of the frame. This platform must feature a square pocket cutout (20mm x 20mm, 10mm deep) designed to hold an optical dust/turbidity sensor, with a 5mm pass-through wire routing hole leading back into the main chassis frame. Export Requirements: Model must feature manifold geometry with rounded fillets on all outer structural edges, optimized for translation to a STEP file format.
