OpenVLA

Overview

OpenVLA is an open-source vision-language-action model that enables robots to perform manipulation tasks by interpreting visual inputs and natural language commands. It combines a vision encoder, a language model, and an action decoder to output control signals. The model is designed to be fine-tuned for specific robots and environments.
