Overview

• American creator Christian Grossi posted videos on September 25 from Zhangjiajie National Park showing a vendor fitting him with the Sport Assist Robot and demonstrating its modes.
• The roughly 1.8 kg knee-mounted unit automatically aids walking, running, and stairs with adjustable power, and at higher settings he said it felt like it was doing the walking.
• Park vendors rent the device to hikers for about $22 per day, and reports from the posts and follow-on coverage put purchase prices around $915 to $950.
• A salesperson described AI-driven sensing that adapts to gait and promoted it as top-tier technology, but outlets did not independently verify specifications, safety testing, or regulatory classification.
• Grossi’s clips amassed millions of views and comments emphasizing potential help for seniors or people with knee problems as well as reactions about Chinese consumer tech and pricing.
