VIGOR Precision and Celanese Corporation are joining forces to tackle one of humanoid robotics’ biggest engineering challenges: weight.
The companies recently signed a strategic partnership agreement at Celanese’s Shanghai Commercial and Technology Center, with plans to develop and commercialize lightweight plastic joint solutions for humanoid robots.
The goal is ambitious: cut the weight of robotic joint modules by more than 30% by replacing traditional metal components with high-performance plastics, while maintaining the precision and durability required for demanding robotic applications.
The partnership comes as advances in artificial intelligence and embodied intelligence accelerate interest in humanoid robots. But heavy metal joint modules remain a major constraint, limiting robots’ endurance, speed and load-bearing performance.
VIGOR, which has more than four decades of experience in precision plastic transmission systems, is bringing its expertise in plastic gears and components to the effort. Celanese will supply high-performance engineering materials and technical support aimed at moving the technology from material development to commercial-scale production.
Hoi-sang Chan, CEO of VIGOR, said the partnership combines the companies’ strengths in materials science and precision manufacturing.
“VIGOR possesses deep technical expertise in precision plastic molding, while Celanese is a global leader in high-performance materials science. Today’s partnership marks a crucial step in infusing ‘material genetics’ into ‘precision manufacturing.’ We look forward to working closely together to achieve the precise formulation of high-performance materials for robotic joints, thereby clearing the way for the large-scale deployment of humanoid robots.”
The companies will focus on materials capable of handling the extreme demands placed on humanoid robot joints, including rapid starts and stops, high-frequency movement and complex loads.
Their development targets include high strength and rigidity, temperature resistance and thermal stability, precision transmission, self-lubrication, lightweighting and dimensional accuracy.
Todd Elliott, Senior Vice President of Celanese Engineered Materials, said robotics is becoming an increasingly important market for advanced materials.
“Robotics is an increasingly important growth area for engineered materials, with customers seeking compact, durable, lightweight and low-noise solutions that can perform reliably in demanding applications,” said Todd Elliott, Senior Vice President, Celanese Engineered Materials. “Through this partnership, we can bring Celanese materials science, application development and local technical capabilities together with VIGOR’s precision gear design and manufacturing expertise to help enable the next generation of robotic motion systems.”
The agreement goes beyond a conventional supplier relationship. Celanese plans to develop customized material solutions based on VIGOR’s technical requirements, with support spanning material commercialization, lifecycle testing and performance consistency during mass production.
The companies say the partnership could help accelerate the shift from metal to high-performance plastics in critical robotic components, potentially making humanoid robots lighter and more efficient.
VIGOR and Celanese plan to expand their collaboration as they pursue commercialization of plastic joint solutions for industrial, commercial and specialized service robots.
