PEEK: The Ultimate Lightweight Material for Humanoid Robots
2025-06-19
Humanoid robots are designed to perform most actions in a human-like manner, which requires a high degree of flexibility. To achieve such flexibility, strict control over the robot’s weight is essential. Excessive weight significantly increases the torque burden on servo motors, which in turn affects the robot’s responsiveness, payload capacity, and battery life. Lightweight design helps reduce th...

A Quick Guide to Rigidity and Flexibility in Polymer Materials
2025-06-05
When discussing polymer materials, we often hear comments like “this material has excellent rigidity” or “that one has outstanding toughness.” Materials with high rigidity usually exhibit greater hardness and resistance to compression and deformation. On the other hand, tough materials are more like flexible ribbons, capable of withstanding stretching and bending with remarkable resilience. But ha...
