Xiangyu Portable Exoskeleton Walking Robot

Xiangyu Medical’s Portable Exoskeleton Walking Robot represents the company’s entry into the powered exoskeleton market, designed specifically for gait rehabilitation in patients with lower limb motor dysfunction. Entering small-batch production in June 2025 with NMPA registration expected by year-end, this 3.2 kg wearable device aims to enable paralyzed patients to achieve standing and walking functions through coordinated robotic assistance.

Product Overview

The Portable Exoskeleton Walking Robot addresses clinical needs for lightweight, user-friendly rehabilitation equipment that can function both in hospital settings and potentially in home environments. Unlike heavier institutional exoskeletons that require significant infrastructure, this device prioritizes portability and ease of use while maintaining therapeutic effectiveness.

Developed through Xiangyu Medical’s Rehabilitation Robot Laboratory, the product incorporates technologies from the company’s collaborations with Xi’an Jiaotong University and Nankai University under national key R&D programs focusing on brain function remodeling and embodied intelligent rehabilitation.

Key Features

Xiangyu Medical’s Portable Exoskeleton Walking Robot is a 3.2 kg gait rehabilitation device featuring 12-motor coordinated drive, AI-based biofeedback personalization, and VR integration.

• Ultra-Lightweight Design: At 3.2 kg, the device enables extended wear periods without excessive fatigue, critical for rehabilitation protocols requiring multiple daily sessions

• 12-Motor Coordinated Drive: Micro servo motors work in coordination with pressure sensors to provide smooth, natural gait assistance

• AI-Driven Personalization: Built-in biofeedback system collects real-time muscle tension data, using AI algorithms to generate individualized training programs with millimeter-level precision

• VR Integration: Compatible with virtual reality training scenarios to increase rehabilitation engagement and effectiveness; can be integrated with ceiling track systems and mobility robots

• Brain-Computer Interface Compatibility: Designed for future integration with Xiangyu’s Sun-BCI Lab products, enabling intention-driven rehabilitation where patients’ motor imagery can directly control exoskeleton movements

Technical Specifications

Xiangyu Medical’s Portable Exoskeleton Walking Robot is a 3.2 kg wearable system driven by 12 micro servo motors with AI adaptive control and optional BCI and VR compatibility.

Clinical Applications

The device targets multiple patient populations requiring gait rehabilitation:

Spinal Cord Injury: Enables patients with paraplegia to achieve standing and assisted walking, supporting neuroplasticity through repetitive motor training

Stroke Recovery: Assists post-stroke patients in relearning walking patterns, with studies indicating rehabilitation periods reduced by approximately 50% compared to traditional methods

Neurological Conditions: Applicable for patients with Parkinson’s disease, multiple sclerosis, and other conditions affecting gait

Orthopedic Recovery: Supports post-surgical rehabilitation for hip and knee replacement patients requiring gait training

Clinical trials at The First Affiliated Hospital of Zhengzhou University demonstrated that patients using the device achieved transition from passive training to independent walking within an average of 3 months, representing a significant reduction from traditional rehabilitation timelines.

Integration with Brain-Computer Interface

A key differentiator of Xiangyu’s approach is the planned integration with non-invasive brain-computer interface technology. The company is developing a Brain-Controlled Exoskeleton Robot that combines the portable exoskeleton with EEG-based intention detection, enabling patients to control the device through motor imagery rather than solely relying on sensor-detected movements.

This integration draws on Xiangyu’s Sun-BCI Lab research, which has achieved motor intention recognition accuracy of 92.7% using neural signal decoding systems trained on large language models. The BCI-integrated version is expected to enter prototype stage in 2025.

Regulatory Status

The company has indicated plans for international market expansion, with CE and FDA registration work progressing for select rehabilitation products.

Market Position

Xiangyu Medical positions the Portable Exoskeleton Walking Robot as a cost-effective domestic alternative in a market historically dominated by imported systems. The company’s established presence in Chinese hospitals—with products serving institutions across all 31 provincial-level administrative regions—provides a substantial distribution network for commercial launch.

The exoskeleton joins a broader portfolio of rehabilitation robots under development at Xiangyu, with the company projecting 7 robot products to receive NMPA registration certificates and 9 additional prototypes to be completed in 2025.

Frequently Asked Questions

When will the Xiangyu Exoskeleton Robot be available for purchase?

The device is expected to receive NMPA medical device registration by late 2025, after which commercial sales will begin through Xiangyu Medical’s established hospital sales channels in China.

How does this compare to other exoskeleton robots in China?

At 3.2 kg, Xiangyu’s portable exoskeleton is among the lighter rehabilitation exoskeletons available, designed specifically for clinical rehabilitation rather than full mobility replacement. The company emphasizes AI-driven personalization and future BCI integration as key differentiators.

Can this exoskeleton be used at home?

The device is initially positioned for hospital and rehabilitation center use. Home applications may be explored following clinical deployment and regulatory approval, pending evaluation of safety protocols for non-supervised use.
