The prompt
Design a 3D CAD model of a fully autonomous humanoid biped robot for the Robofest AI HOMO BOT competition. Dimensions Height: 800 mm (80 cm) Maximum weight: 20 kg Lightweight modular frame using 6061 aluminum with 3D-printed covers/brackets. Structure Humanoid body with Head, Torso, Two Arms, Two Legs, and Feet. Internal compartments for electronics with proper cable routing and maintenance access. Degrees of Freedom (26 DOF) Head: 2 DOF (Yaw, Pitch) Each Arm: 6 DOF (Shoulder 3, Elbow 1, Wrist 2) Each Leg: 6 DOF (Hip 3, Knee 1, Ankle 2) Component Mounting Space Include dedicated mounting locations for: NVIDIA Jetson Orin NX RGB Camera + Depth Camera (Head) STM32 Controller Motor Controllers 24V Li-ion Battery Power Management Board 9-Axis IMU (Torso) LiDAR/ToF Sensor (Front/Chest) Joint Encoders FSR Sensors (Feet) Emergency Stop Button (Chest) Design Requirements Stable biped walking geometry Low center of gravity Internal wiring channels Ventilation for Jetson cooling Protective joint covers Wide anti-slip feet Realistic servo motor housings at every joint Clean, manufacturable engineering design (not futuristic) Generate a complete assembly with front, side, top, rear, isometric, exploded, and transparent internal views showing all component locations.
