Flashspoter - NVIDIA has officially introduced the Isaac GR00T Reference Humanoid Robot, the first fully open humanoid robot reference platform. The announcement was made during the Taipei GTC event and was part of Jensen Huang's keynote address at Computex. The Platform is designed to unite physical robot components with computing systems and software based on artificial intelligence. This step was taken to answer the needs of robotics research that has been hampered by the fragmented development process.
This Platform uses a Unitree H2 chassis that reaches almost 6 feet or about 180 centimeters in height with a weight of 150 pounds. The Robot has 31 degrees of freedom throughout its body and is equipped with a pair of five-sided Sharpa Wave arms that have 22 degrees of freedom. Combined, the entire system including the hands has 75 degrees of freedom. In order to manipulate objects accurately, the robotic hand is equipped with touch-sensitive sensors as well as a wrist camera. This h2 chassis is listed on the Unitree website at a price of 29,900 US dollars.
The brain of this robot is the NVIDIA Jetson AGX Thor t5000 computing system with a Blackwell GPU. The system has AI capabilities of up to 2,070 TFLOPS in FP4 format as well as 128GB of integrated memory. Its power consumption can be set between 40 and 130 Watts depending on the processing requirements. The Robot is also equipped with a 15ah battery with a capacity of almost 1 kWh capable of supplying power for up to three hours of operation. For safety, a remote emergency button is available to stop the robot at once.
The Robot is equipped with various sensors, including a stereo camera in the head with a wide field of view. There are also cameras on both wrists to support close-up vision as well as inertial measurement units. The control system of this robot can push the arm torque to 120 Newton-meters and the leg torque to 360. The Robot can handle working loads of 7 kilograms with a peak load of 15 kilograms. Besides a range of microphones and loudspeakers for voice interaction, it supports Ethernet, Wi-Fi 6, and Bluetooth 5.2.
The reason why this platform differs from other humanoid robots is NVIDIA's open approach. The company provides Isaac GR00t software and models that are freely accessible to researchers. This development Platform is modular, so the research team can use the entire stack or only part of it as needed. This reference Robot will also support the cheaper Unitree G1 and is already widely used in research institutions. NVIDIA first introduced the gr00t N1 Foundation model in March.
The unique value of this announcement is NVIDIA's efforts to democratize advanced humanoid robotics research. It used to be that researchers had a fragmented pipeline, switching between hardware setup, data collection, and physical testing without a unified system. By providing an open design reference, NVIDIA is enabling more institutions to participate in high-end research without the need to build infrastructure from scratch. This is in contrast to the closed-door approach that has been practiced by other commercial robotics companies.
Several leading institutions have stated that they will use this design reference. They include Ai2, ETH Zurich, Stanford Robotics Center, and UC San Diego. Stanford says the open approach allows for faster code sharing and testing of ideas on physical machines. ETH Zurich emphasizes the importance of platforms for collecting data and testing algorithms in the real world. Researchers from these various institutions see the platform as a step forward for creating more competent and useful robotics systems.
NVIDIA states that the Isaac GR00T Reference Humanoid Robot will be available from Unitree by the end of 2026. Meanwhile, the reference workflow for Unitree G1 is expected to be available soon on GitHub and Hugging Face. NVIDIA is allotting time of about a year and a half to the research ecosystem for preparation. The absence of a physical robot demonstration in the presentation is an important note, as it is still a reference platform. However, the involvement of reputable research institutions shows that this ecosystem has a serious Foundation.
NVIDIA's decision to open a humanoid robot platform could change the dynamics of competition in the industry. So far, the development of humanoid robots has been dominated by several companies with expensive closed systems. By providing open references, NVIDIA is actually driving the acceleration of collective innovation. This strategy is similar to what the company did in GPU computing in the last decade. If successful, NVIDIA will not only sell computing components, but become the center of the entire global humanoid robotics ecosystem. An added value for researchers is access to ready-to-use systems with lower research costs, accelerating the realization of general physical intelligence on a multitrillion-dollar industrial scale.
