The prompt
Create a mechanical CAD model for a small remote-controlled robotic seed-sowing jeep for a university Mechanical Engineering Technology final-year project. Use approximate overall dimensions of 600 mm length, 450 mm width and 450 mm height. Include a rectangular metal chassis, four large agricultural treaded wheels, a rear-mounted seed hopper, a seed-metering drum, seed delivery tubes, a front furrow opener, a rear soil-covering roller, and mounting brackets for 12V DC geared motors and a battery. Use realistic mechanical shapes and millimetre dimensions. Design components as separate manufacturable parts where possible. Keep the design simple, lightweight, low-cost and suitable for a student prototype. Export engineering geometry in STEP format for SolidWorks.
