The prompt
"Design a miniature robotic assistant inspired by Dummy from Iron Man. The robot should be 6–10 cm tall with an adjustable telescopic height. It should have four robotic arms, each with a servo-powered gripper capable of picking up small objects. The body should be designed with two hollow compartments (top and bottom) to house the microcontroller, batteries, servo drivers, wiring, and other electronics. All wires should be routed internally so that no cables are visible from the outside, giving the robot a clean, realistic appearance. Include removable access panels for maintenance. Provide a complete 3D CAD model with dimensions, exploded assembly views, a bill of materials, and recommendations for 3D-printable materials. Design the frame to support internal cable routing, servo mounting, and future upgrades. Also provide wiring diagrams, Arduino/ESP32 code, assembly instructions, and suggestions for balancing the robot's weight and keeping the base stable."
