Where Motors Are Used in Humanoids
Humanoid robots are transitioning from research platforms into commercial and industrial applications across logistics, manufacturing, inspection, and human-assist environments. In today’s blog, we explore where motors are used in humanoid robots and how actuator requirements vary across different joints within the system.
For a more detailed technical overview, you can download our selection guide to motors for humanoid robotics systems here.
Humanoid robots are composed of multiple joint groups, including the lower body, upper body, hands and end-effectors, torso, and neck and head, each with distinct motion and control characteristics.
Lower Body Joint Motors
Lower body joints are responsible for locomotion and load-bearing tasks. They operate under high, continuously varying torque demands and must withstand impacts while maintaining stable and controlled motion.
Upper Body Joint Motors
Upper body joints handle coordination and manipulation tasks, where precision and controlled movement are important.
Hand and End-Effector Motors
Hands and end-effectors require fast response and fine positional control for interaction with objects and environments. Actuators are designed with low inertia, minimal cogging, high-resolution feedback sensing, and tight control loops to enable dexterous interaction.
Torso Motors
The torso supports system-wide balance and distributes motion across the robot.
Neck and Head Joint Motors
Neck and head joints manage orientation and sensor alignment. They require smooth control to support sensor stabilization and safe human interaction.
