Chinese Humanoid Robot STF-D9 Performs Household Tasks, Targets Senior Care

Chinese firm Zhuhai Tianwei New Technology has unveiled the STF-D9 humanoid robot, capable of cooking, washing clothes, and providing senior care, according to a report by The Times of India. The robot stands 1.7 meters tall, weighs 55 kg, and incorporates joint modules with direct-drive control for smooth, human-like motion. Its design targets domestic assistance, with a focus on reducing caregiver burden.

The STF-D9 features a modular architecture with 34 degrees of freedom, enabling it to perform complex bimanual tasks such as stirring a wok, folding laundry, and assisting elderly individuals with mobility. The robot uses a combination of RGB-D cameras, LiDAR, and force-torque sensors for perception and manipulation. Its walking speed is reported at 3 km/h, with a maximum payload of 10 kg per arm. The robot’s battery provides 2–3 hours of continuous operation.

Zhuhai Tianwei New Technology, a subsidiary of China Aerospace Science and Industry Corporation (CASIC), positions the STF-D9 as a commercial solution for the growing elderly care market in China, where the population over 60 is expected to exceed 400 million by 2035. The company claims the robot can reduce reliance on human caregivers by handling routine chores and providing companionship. However, the report notes that the robot costs approximately ¥300,000 (about $41,500 USD), which may limit adoption to institutional buyers.

The STF-D9 employs a model-based predictive control framework for locomotion, similar to humanoid platforms like Boston Dynamics’ Atlas, though at lower dynamic capability. Its ability to perform whole-body manipulation, such as carrying a tray while walking, suggests advancements in coordinated motion planning. Compared to Xiaomi’s CyberOne or Tesla’s Optimus, the STF-D9 emphasizes domestic chores over industrial tasks. Challenges include limited battery life and high unit cost. Industry analysts expect humanoid robots to enter senior care facilities in China within five years, driven by labor shortages and government support for robotics in aging societies.
