engineering robot 3d model

A futuristic humanoid surveillance robot with a tracked tank base, designed for campus security monitoring. The robot has a semi-transparent mechanical body showing internal electronic components. Inside the chest is a Raspberry Pi 5 and Arduino Mega boards connected with colorful wires. The head contains a Pi camera module acting as eyes with a small servo motor for movement. The robot includes sensors such as PIR motion sensor and gas/smoke sensor mounted on the body. It also includes small speakers, buzzer, relay modules, and a WiFi antenna for communication. The lower body contains motor drivers, a voltage regulator (buck converter), and a high capacity battery pack powering DC geared motors that drive the tracked wheels. The design should look like a realistic engineering prototype robot with visible wiring, circuit boards, and mechanical parts. The robot should stand upright with a modern industrial robotics style, high detail, clean mechanical structure, and educational robotics lab design. 3D mecha
