The prompt
Design a cute futuristic robot dog cad inspired by EMO robot and Sony Aibo. The robot should have 4 mechanical legs and a small rounded tail on the back. The body must be compact, lightweight, modern, and fully 3D printable. The front of the robot should contain a rectangular opening for a 0.96 inch OLED display (SSD1306) to show animated eyes and emotions. The face area should look expressive and friendly. The robot body must be hollow inside to fit all electronics and wiring. Create proper internal compartments and mounting points for the following components: * ESP32 DevKitC board (approx. 55mm x 28mm x 8mm) * PCA9685 servo driver (approx. 55mm x 28mm x 8mm) * 4 SG90 servo motors for the legs * 2x 18650 batteries * TP4056 charging module * Active buzzer * Wiring and connectors The internal space should include extra clearance for cable management and airflow. Add screw holes, mounting brackets, and removable top cover for easy assembly and maintenance. Recommended internal usable dimensions: * Length: 120 mm minimum * Width: 70 mm minimum * Height: 50 mm minimum Overall robot dimensions should be approximately: * Length: 180 mm * Width: 110 mm * Height: 115 mm The leg mounting system should support smooth walking motion using one SG90 servo motor per leg. The design should keep the center of gravity low for stability. Style requirements: * Rounded edges * Smooth futuristic curves * Cute companion robot aesthetic * EMO-inspired face * Clean modern design * Hidden cable routing if possible Output should be suitable for editable 3D CAD and STL export.
