The prompt
Create a compact automatic cat feeder designed for an adult cat. Overall dimensions: - Width: 350 mm - Depth: 250 mm - Height: 380 mm - Wall thickness: 5 mm Food system: - Food hopper: 100 × 100 × 130 mm - Hopper outlet: 40 × 40 mm - Flap chamber directly below the hopper: 100 × 100 × 70 mm - Conveyor belt: 150 × 100 mm - Two conveyor rollers, approximately 30 mm diameter - Food bowl: 160 × 120 × 50 mm - Leave approximately 30 mm between the conveyor outlet and the food bowl. - The food bowl must be mounted on a load cell and must not touch the surrounding structure. Water system: - Separate water tank: 120 × 120 × 150 mm - Water bowl: 150 × 120 × 50 mm - Keep the water system physically separated from the electronics. Electronics: - Electronics compartment: 180 × 120 × 70 mm - Leave space for an Arduino Uno, HX711, RTC module, wiring and motor drivers. - Include cable-routing openings. Sensors: - HC-SR04 mounted above the food hopper, pointing downward. - PIR sensor mounted toward the front of the feeder. - Load cell mounted below the food bowl. Actuators: - Stepper motor mounting area for a 28BYJ-48 to operate the food flap. - DC motor mounting area for the conveyor. - Water pump mounting area. - Buzzer and LED indicator mounting areas. Design requirements: - Separate components where practical. - Suitable for 3D printing. - Avoid cardboard. - Rounded external edges. - Include mounting points and screw holes where appropriate. - Keep the food path accessible for cleaning. - Keep electronics protected from food and water. - Prioritize a practical compact mechanical design over decorative details.
