Core Product Overview
The G1 EDU Ultimate C (U5) is a compact bipedal humanoid standing approximately 132cm tall. It is distinguished by its 41 Degrees of Freedom (DoF) and the inclusion of dual Inspire 5-finger dexterous hands equipped with tactile sensors. This model is designed for labs and developers focusing on fine motor skills, imitation learning, and complex human-robot interaction.

Technical Highlights
1. Human-Like Dexterity
The “Ultimate C” designation specifically refers to the hand configuration. Unlike the Ultimate A (3-finger) or Ultimate B (3-finger tactile), the U5 features:
-
Dual Inspire Hands: Full 5-finger anthropomorphic design.
-
Tactile Feedback: Integrated sensor arrays in the fingertips for delicate object handling and force-sensitive tasks.
-
7-DoF Arms: Enhanced range of motion compared to the 5-DoF arms found in entry-level EDU models.
2. Research-Grade AI & SDK
The U5 is an “EDU” model, meaning it is fully unlocked for secondary development:
-
100 TOPS AI Module: Powered by NVIDIA Jetson Orin, allowing for on-board real-time reinforcement learning and computer vision.
-
Full SDK Support: Compatible with ROS 2, Python, and C++, providing low-level access to joint motor control and high-level sensor data.
-
Audio Interaction: A 4-microphone array and 5W speaker support voice-command integration and sound localization research.
3. Mobility and Build
-
Foldable Design: The robot collapses to 690 x 450 x 300mm, making it portable enough to fit in a large suitcase.
-
Hollow Joint Wiring: Ensures no external cables are exposed, reducing the risk of snags during complex movements.
-
Dynamic Balance: Capable of walking at speeds up to 2.0 m/s and recovering from impacts or uneven terrain.
Note on 2026 Availability: As of March 2026, the G1 series has received significant firmware updates (v3.2+) which have improved walking stability and introduced native support for Large Language Models (LLMs) to facilitate natural language task execution.
