This paper presents heuristic design methodologies for humanoid robots developed through practical experience in international humanoid robot competitions. Since humanoid robot development requires close integration between design and engineering, this study proposes an approach that connects technical requirements with design-oriented decision-making. The proposed approach focuses on mechanical and electrical design strategies derived from repeated prototyping, testing, and competition-based refinement. For mechanical design, this paper introduces lightweight structural concepts and optimized wiring layouts using hollow shafts. These strategies improve robustness, reduce unnecessary weight, and support efficient dynamic movement in diverse environments. For electrical design, the paper explains component selection based on performance, reliability, and operational efficiency. Main and sub controllers, sensors, actuators, and communication modules are selected to support control algorithms, artificial intelligence (AI), real-time data processing, and stable communication. Based on practical experience, this paper discusses key challenges in humanoid robot development and practical solutions obtained through iterative improvement. By sharing design strategies grounded in real-world implementation, this research offers useful insights for developing effective humanoid robot platforms.
