Model Information

Description
Gemini Robotics On-Device is a state-of-the-art Vision-Language-Action (VLA) model based on
our on-device Gemma models. It is designed for general-purpose robotic manipulation, operating
efficiently on local devices. This model supports a wide range of tasks, scenes, and multiple robot
types. It is currently available to a select group of trusted testers.

Inputs
Text (e.g., a question or instruction), images (e.g., robot’s perspective of the environment), and
robot proprioception as numerical values.

Outputs
Robot actions as numerical values.

Architecture
Gemini Robotics On-Device is an on-device VLA model based on Gemini Robotics 1.5 technology
and our on-device Gemma models.

Model Data

Training Dataset
Gemini Robotics On-Device was trained on datasets consisting of images, text, and robot sensor
and action data.

                                                                                                       2
Training Data Processing
Data filtering and preprocessing included techniques such as deduplication, safety filtering in line
with Google's commitment to advancing AI safely and responsibly and quality filtering to mitigate
risks and improve training data reliability.

Implementation and Sustainability

Hardware
Gemini Robotics On-Device was trained using Google’s Tensor Processing Units (TPUs). TPUs are
specifically designed to handle the massive computations involved in training LLMs and can speed
up training considerably compared to CPUs. TPUs come with large amounts of high-bandwidth
memory, allowing for the handling of large models and batch sizes during training, which can lead
to better model quality. TPU Pods (large clusters of TPUs) also provide a scalable solution for
handling the growing complexity of large foundation models. Training can be distributed across
multiple TPU devices for faster and more efficient processing.

The efficiencies gained through the use of TPUs are aligned with Google's commitment to operate
sustainably.

Software
Training was done using JAX and ML Pathways.​

Distribution
Gemini Robotics On-Device 2 is distributed only to Trusted Testers (signup link).

Evaluation
Approach
Gemini Robotics On-Device was evaluated on several simulation and on-robot benchmarks. This
evaluation assessed scene, instruction, and action generalization, as well as instruction following
for tasks outside the training data distribution.

                                                                                                       3
Results
Gemini Robotics On-Device 2 demonstrates substantial performance advancements over Gemini
Robotics On-Device 1 across diverse robotic embodiments. When evaluated on novel platforms
introduced exclusively during post-training, Gemini Robotics On-Device 2 exhibits faster and more
efficient learning and achieves a significantly higher final success rate.

Intended Usage and Limitations

Intended Usage
The Gemini Robotics On-Device model is a VLA model designed for on-device deployment in robotics
applications, offering competitive results to larger models (like Gemini Robotics VLA) on in-domain tasks.
The model allows for efficient on-robot inference and is trained to provide a general base for a variety of
tasks on bi-arm robots. Its intended use is to serve as a core component in robotics systems, enabling
them to understand and respond to linguistic instructions, and to act in a given environment.

Known Limitations
The Gemini Robotics On-Device model is limited in its ability to generalise to out of distribution
tasks as well as controlling high-degree-of-freedom robots.

Ethics and Safety
Safety Evaluations, Risks, and Mitigations: Gemini Robotics On-Device was developed in partnership
with our internal safety, security, and responsibility teams. For specific physical embodiments, we
conducted safety evaluations and red-teaming, tracking metrics such as collision rates, motion quality,
and out-of-distribution robustness.

Gemini Robotics On-Device inherently minimizes standard generative content risks by restricting its
outputs to physical actions rather than text. Because it has been evaluated primarily on standing bi-arm
manipulation tasks, risks associated with mobile platforms or whole-body control are outside its current
scope. We recommend a layered approach to safety: interfacing VLAs with Embodied Reasoning models
for high-level semantic safety; using low-level controllers for collision-free motion planning, balance and
force control, and implementing hardware-specific functional safety mechanisms.
