How to choose bearings for humanoid robots?
When choosing bearings for a humanoid robot, it’s crucial to match the bearing type with the specific joint’s function, load, speed, and precision requirements. Ball bearings and roller bearings are commonly used for general rotation and high-load joints like the shoulders and hips, while needle bearings and miniature ball bearings are ideal for small, precise movements in areas like the fingers and wrists. Slewing bearings are suitable for large, high-load joints such as the waist and hips. By selecting the right bearing for each part, the robot can achieve smooth, efficient, and durable movement.
