Create a high-detail 3D model of a small, rugged robot inspired by WALL·E. The robot should have a boxy, weathered metal body, expressive binocular-style eyes on a flexible neck, and two tank-like tire tracks for movement. Add subtle dirt, scratches, and rust to give it a used, realistic look. The tires should be thick, rubbery, and detailed with treads. Include movable arms with claw-style hands. The overall look should balance cuteness with mechanical realism, optimized for animation and high-quality rendering in Unity or Unreal Engine.
