Humanoid robot market growth drives innovation in components and actuation

The humanoid robot market is experiencing rapid growth, with projections suggesting the industry could reach $43.8 billion by 2035. This expansion is driving significant investment in specialized components and advanced actuation technologies.

In China, startups like Stella-Robot are pivoting toward wire-driven technology, a method inspired by Tesla’s Optimus. Unlike traditional direct-drive systems that place motors inside robotic fingers, wire-driven systems move motors to the forearm or elsewhere. This approach reduces heat, lowers hand weight, and improves the longevity of tactile sensors. Stella-Robot has developed the ‘Pantheon Hand 20’, which utilizes an automated tension adjustment algorithm to manage wire stretching and wear.

Parallel to hardware advancements, the supply chain for robot components is becoming a focal point for investors. Companies such as Hesai Group and Parker-Hannifin are positioned to benefit from the demand for essential parts. Hesai provides high-performance 3D lidar for precise spatial navigation and depth perception, while Parker-Hannifin supplies motion and control technologies necessary for joint articulation and power distribution.
