Advanced Manipulation & Mobility
The U3 model stands out due to its Dex3-1 hands. Unlike the base “dummy” hands, these utilize force-position hybrid control, allowing the robot to handle delicate objects—like opening bottles or holding tools—with human-like sensitivity. Its 3-DoF waist allows the robot to twist and lean, significantly expanding the workspace of its arms compared to the 1-DoF entry-level models.
Sensing & AI Integration
-
360° Perception: Equipped with a Livox MID-360 3D LiDAR and an Intel RealSense D435i depth camera for real-time mapping and obstacle avoidance.
-
Audio Interaction: Features a 4-microphone array for voice command recognition and a 5W stereo speaker.
-
Secondary Development: Full support for ROS2, C++, and Python. The integrated Jetson Orin module allows for on-board deployment of Large Language Models (LLMs) and reinforcement learning algorithms.
Build Quality
The G1 is built with a combination of aerospace-grade aluminum and high-strength engineering plastics. One of its most practical features is its foldable design, allowing it to shrink down to 690 x 450 x 300 mm for easy transport in a standard suitcase.
Note: The “Ultimate A” (U3) specifically features the Dex3-1 hands without tactile sensors. If you require pressure-sensitive “skin” on the fingertips, you would typically look at the Ultimate B (U4) configuration.
