autonomous robot 3d model

Create a highly realistic, engineering-grade 3D prototype of a SINGLE autonomous mobile robot designed specifically for the Robotics for Good Youth Challenge 2026–2027 public-health-emergency competition. IMPORTANT: This is ONE robot only, not two robots. The design must be based on the ATTACHED BASE IMAGE provided by the user. Preserve the general chassis/base concept, wheel arrangement and overall proportions of the attached base while intelligently adding the required competition mechanisms. ROBOT SIZE: Target chassis footprint: WIDTH = 28 cm / 280 mm LENGTH = 32 cm / 320 mm Keep the entire robot compact enough to fit inside the official 480 × 280 mm starting zone when positioned correctly before the match. Avoid any permanent mechanism that creates an unnecessarily large starting footprint. PROCESSOR / COMPUTING: Do NOT use Raspberry Pi. Use an ARM-based microcontroller/processor as the main controller, preferably represented as an embedded ARM Cortex-M development board. Show
