In the ever-evolving robotics landscape, achieving precise and seamless motion is paramount. While articulating joints enable a robot’s range of motion, bearings serve as the backbone, ensuring smooth and accurate movement. Particularly in humanoid robots where precision is non-negotiable, the selection of bearings becomes a critical engineering decision. Design engineers must consider the diverse range of robotic bearings, how backlash affects precision, and when to use seals to protect bearings from harsh environments.
