The prompt
Create a complete editable 3D engineering design of NEXUS Generation 1, a compact rugged two-wheel autonomous Arduino rover. Overall dimensions: - Width: 260 mm - Depth: 300 mm - Height: 150 mm Include: - Rectangular chassis, 200 mm wide, 280 mm deep and 3 mm thick. - Two 80 mm rubber wheels, 30 mm wide. - Two geared DC motors. - Rear caster wheel. - Sloped front bumper. - Arduino Uno R3. - Dual motor driver. - Front-facing HC-SR04 ultrasonic sensor. - Battery compartment, 100 × 70 × 40 mm. - Two front white lights and two rear red lights. - Reserved space for a future camera and Raspberry Pi 5. Use separate named components, accurate proportions, visible mounting positions and a low centre of gravity. Show top, front, side and 3D perspective views. Make the design editable and allow individual components to be moved. This is a conceptual engineering assembly, not a verified manufacturing or electrical design.
