Abstract	This paper presents the design and development of a fully equipped humanoid robot named AI Bot. It supports voice interaction, vision, mechanical movement, and internet-based intelligence. The platform combines a Raspberry Pi 5 for AI processing and online APIs, ESP32‑CAM for visual sensing, and Arduino Mega 2560 + RAMPS 1.4 for motor control. The AI Bot can answer verbal queries, perform physical gestures, and access live content from Google Search, YouTube, and Wikipedia to respond intelligently. It is powered by a 12 V, 400 W, 400 A supply, ensuring sufficient current for servo and stepper operations. The robot can access the internet via a GSM module, enabling wireless connectivity in mobile scenarios. This makes AI Bot suitable for use in education, assistance, and interactive robotics.
