Humanoid robots are complex systems that integrate mechanical, electronic, and control technologies, with their mobility heavily dependent on advancements in motor technology. As the "power heart" of a robot, motors directly influence flexibility, precision, and load capacity. This article explores the core motor types used in humanoid robots and their applications.

If we compare a humanoid robot to an athlete, joint motors are its powerful and dynamic “muscle system.” While AI algorithms and advanced sensors often get the spotlight, it is the actuators—the joint motors embedded in each limb—that truly bring robots to life with fluid and purposeful movement.
Over the past decade, AI and perception technologies have advanced rapidly. However, without robust, responsive, and flexible actuators, humanoid robots cannot transition from lab demonstrations to real-world applications. Today, breakthroughs in joint motor technology are helping robots cross the final threshold from "mechanical motion" to "biological agility."
