autonomous robot 3d model

Photorealistic isometric 3D render of a compact 20x20x20 cm autonomous competition robot. Two-tier laser-cut acrylic chassis. Four holonomic omni-directional wheels mounted at 45-degree angles on the corners. The front features a U-shaped cutout with a spinning rubber roller mechanism for collecting ping pong balls. The top deck holds an exposed Arduino microcontroller board, a small forward-facing camera module, and a prominent red emergency stop button. Color palette: black, silver, white, and green. Strictly NO orange and NO purple colors anywhere on the robot. Clean studio lighting, engineering aesthetic, high technical detail.
