The prompt
Design a compact four-wheel agricultural robot chassis for 3D printing. The front of the robot has an inclined slide platform that stores seeds. At the bottom of the slide is a vertical gate operated by two servo motors. When the gate lifts upward, seeds slide down the inclined platform by gravity. Include mounts for an Arduino Mega 2560, L298N motor driver, HC-SR04 ultrasonic sensor, battery compartment, and four DC gear motors. Make the chassis modular with screw holes and printable as separate parts.
