Changsha Youlong Robot Co., Ltd. - 长沙优龙机器人有限公司

EULON, the operating brand of Changsha Youlong Robot Co., Ltd., is a Changsha-based developer and manufacturer of exoskeleton and rehabilitation robots founded in April 2020. The company positions itself as an integrated player covering independent research and development, large-scale production, and market sales of wearable robotic devices, built on three core technical pillars: biomimetic structural design, hardware control technology, and intelligent software algorithms. In 2021 EULON established a joint laboratory with the Shenzhen Institute of Advanced Technology under the Chinese Academy of Sciences to support its rehabilitation robotics research.

The company's product line centers on lower-limb assistance and ankle rehabilitation. Its Ruyi series of ankle walking-assist training devices uses multi-sensor gait processing to record and analyze walking patterns, with the newer Ruyi 2.0 generation adding a redesigned drive mechanism and AI-based gait recognition reported at 99 percent accuracy. The Youlong 1.0 PRO is an AI-powered motion-assist exoskeleton aimed at long-distance walking and hiking support, offering extended battery life, six terrain-adaptive modes for flat ground, slopes, mountain trails and stairs, dual-filter anti-interference control, and AI intent recognition to anticipate the wearer's movement. A companion ankle trainer, marketed as Yunlu, uses a magnetic quick-release closure and adjustable dorsiflexion assist torque for ergonomic fit.

EULON's Youlong flexible exoskeleton series received a Class II medical device registration in China in 2024 and was included in a 2024 national catalogue promoting products for the elderly population, reflecting the company's focus on aging-related mobility support alongside consumer and outdoor use cases. The company has also been recognized with a First Prize in the Guangdong Provincial Science and Technology Award for Technological Invention in 2023 and a 2023 Science and Technology Award from the Chinese Society of Rehabilitation Medicine, and its work has been covered by national broadcaster CCTV. EULON disclosed a strategic investment round in May 2025, though the amount and investors were not publicly detailed.

Operating from a facility in Changsha's Xihu Science and Innovation Park in Hunan province, EULON positions itself within China's growing rehabilitation-robotics and assistive-mobility sector, serving hospitals, rehabilitation centers, and increasingly consumer and elder-care channels with its exoskeleton and ankle training devices.
