AI Technical Summary
Existing cables in humanoid robot joint modules have low mechanical strength, poor wear resistance, are easily worn, and have weak resistance to electromagnetic interference, affecting motion accuracy and lifespan.
A torsion-resistant and bending-resistant cable is prepared by using a sheath layer composed of thermoplastic polyurethane elastomer, polyether block polyamide elastomer, composite filler and polytetrafluoroethylene microcapsules through blending and extrusion processes. The material properties are enhanced by a hybrid network of carbon nanotubes and tungsten disulfide, and the polytetrafluoroethylene microcapsules provide distributed lubrication.
This technology achieves high elasticity, wear resistance, and self-lubricating properties in cables across a wide temperature range, extending lubrication life, improving motion accuracy and response speed, reducing friction noise, and extending service life.
