Engineering Challenges in Humanoid Robot Dev: From Sim to Real

ChongZzZhang · x · 2026-08-19

A developer outlined the engineering workflow required to add a simple degree of freedom (like running) to a humanoid robot. It involves redesigning actuator layouts and cooling systems, identifying inertia parameters, remodeling the real robot (URDF), integrating it into the simulation, retraining controllers, and tuning Sim-to-Real transfer. Algorithm tuning alone can take a month of intense work, followed by hardware durability checks.
