Stial Steven: First humanoid robot for intricate polishing tasks unveiled in China

14 February 2025


Stial Steven adjusts force, angles, and paths in real time using AI, 6D sensors, and a process database for precise polishing.

A Chinese technology firm has introduced the first humanoid robot built exclusively for polishing tasks.

Unlike conventional robotic arms, Stial Technologies’ humanoid, Stial Steven, imitates human movements for increased flexibility and adaptability.

Its design is excellent at handling intricate workpieces, fine polishing, and precisely operating in confined places, all of which increase productivity for jobs requiring sensitive surface finishing in a variety of sectors.

To solidify its position in 6D force sensor technology and facilitate the smooth transition from core hardware to intelligent software, Stial also purchased a domestic sensor technology company, STFcore (ZhongQing Technology).

Precision robotics unleashed

Stial’s latest acquisition marks a breakthrough with the launch of Stial Steven, the world’s first humanoid robot designed specifically for polishing applications.

Stial Steven replicates human-like motion, providing greater flexibility and adaptability than conventional industrial robotic arms. This feature makes it perfect for delicate polishing on intricate workpieces where accuracy is essential, as well as in confined areas.

The humanoid can dynamically modify force, angles, and trajectories in real-time thanks to its proprietary process database, sophisticated 6D force sensors, and a multimodal AI model that combines vision, haptics, and aural awareness.

The company claims that the flexibility enables it to perform complex polishing jobs with remarkable precision, greatly enhancing productivity and quality.

The robot excels at working on complex curved surfaces and performing high-precision polishing on small components. Its ability to replicate human-level detail while operating continuously enhances productivity and competitiveness for industries requiring meticulous surface finishing.

Stial asserts that by surpassing the constraints of conventional robots, Stial Steven establishes a new benchmark in automated polishing, allowing companies to attain more processing precision, lower labor costs, and increased consistency. It so marks a major advancement in robotic automation and opens the door to more clever and effective industrial solutions.

Force-sensing breakthrough

In high-precision manufacturing, 6D force sensors are essential for enabling robots to perform precise operations with adaptive control. These sensors monitor real-time contact forces between the robot and the workpiece, transmitting data to Stial’s proprietary NextBrain AI system. This allows dynamic adjustments to polishing pressure, direction, and angle, ensuring optimal flexibility and control.

In addition to polishing, 6D force sensors are an essential part of humanoid robots, greatly enhancing their entire performance. By purchasing STFcore, Stial was able to obtain state-of-the-art 6D force sensor technology, which, when paired with its adaptable force control algorithms, significantly increased its force-controlled polishing capabilities.

Stial claims its competitive edge is strengthened by this strategic acquisition, which guarantees deep integration from intelligent software to core hardware. By developing algorithms for force, vision, and auditory perception in addition to process data collection, Stial hopes to further improve AI multimodal technology. These developments will propel the advancement of polishing robotics toward more accuracy, intelligence, and efficiency. “Looking ahead, we will continue to advance AI and robotics, reshaping industrial production as a vertical ecosystem builder, and leveraging internationalization to create a new paradigm in global intelligent manufacturing,” said Hongbo Wang, Stial’s Founder & CEO, in a statement.
