Indoor whole-house dynamic scanning
🤖 Unitree L2 enables rapid ⚡ and precise 🎯 acquisition of a home’s complete 🏠 3D structural data, supporting accurate positioning 📍 and autonomous navigation 🚀 for mobile robots. It also empowers robots to extend their capabilities to diverse tasks such as whole‑house cleaning 🧹 and organization 📦.
Outdoor real-scene dynamic scanning
💡Unitree L2 can effectively resist interference from indoor ambient light 🏠 and outdoor strong light ☀️. Even under intense outdoor illumination of 100Klux 🌞, it achieves stable ranging 📏 and high‑precision mapping 🗺️.
Non-repetitive scanning
📡 Unitree L2 achieves high‑precision 🎯 and high‑density 🌐 point cloud data through omnidirectional ultra‑wide‑angle 🔭 non‑repetitive scanning, delivering photograph‑level 📸 scanning effects.
