PRTS: A Primitive Reasoning and Tasking System via Contrastive Representations
Researchers introduce PRTS, a Vision-Language-Action foundation model that reformulates robotic learning through goal-conditioned reinforcement learning rather than traditional behavior cloning. The system learns to assess goal reachability by embedding state-action pairs and language instructions in a unified space, achieving state-of-the-art performance on multiple robotic benchmarks and real-world tasks.
