Openvla
Overview :
OpenVLA is a 700-million-parameter open-source VLA model pre-trained on 970k robot episodes from the Open X-Embodiment dataset. This model sets a new industry standard for generic robot operation policies, enabling out-of-the-box control of multiple robots and rapid adaptation to new robot setups through parameter-efficient fine-tuning. OpenVLA's checkpoints and PyTorch training procedures are completely open-source, allowing the model to be downloaded and fine-tuned from HuggingFace.
Target Users :
The OpenVLA model is primarily aimed at robotics researchers and developers, especially teams that need to rapidly deploy and adapt to a variety of robot operation tasks. Its open-source nature and efficient fine-tuning capabilities allow researchers and engineers to easily apply the model to different robotics platforms and operation scenarios.
Use Cases
Control a Franka Panda robot using OpenVLA to complete an object placement task on a desktop.
Deploy OpenVLA on a WidowX robot to perform complex object manipulation and environmental interactions.
Apply OpenVLA to a Google robot to enable object manipulation based on natural language instructions.
Features
Supports control of multiple robotics platforms without requiring additional training.
Rapidly adapts to new robot setups through parameter-efficient fine-tuning.
Exhibits outstanding performance in visual, motor, physical, and semantic generalization tasks.
Pre-trained using the Prismatic-7B VLM, incorporating a fused visual encoder, projector, and Llama 2 7B language model.
Effectively combines language instructions with behavior in multi-task, multi-object environments.
Achieves parameter-efficient fine-tuning through LoRA technology, fine-tuning only 1.4% of the parameters.
How to Use
1. Visit the HuggingFace website and download the OpenVLA model checkpoint.
2. Set up a PyTorch training environment and ensure all dependencies are correctly installed.
3. Fine-tune OpenVLA based on the specific robot platform and task requirements.
4. Utilize LoRA techniques or other parameter-efficient methods to optimize model performance.
5. Deploy the fine-tuned model on the robot and conduct practical operation tests.
6. Based on the test results, further adjust model parameters to suit more complex operation tasks.
