Researchers have developed ProgVLA, a compact vision-language-action model for robot manipulation that efficiently handles long multi-modal sequences. It uses a Perceiver resampling scheme to compress visual, language, and proprioceptive data into a fixed set of context tokens. The model also incorporates progress heads trained with reinforcement learning to estimate task completion, enabling more effective imitation learning. A 0.1B-parameter version of ProgVLA has demonstrated competitive success rates against larger models on manipulation benchmarks and has been validated in real-world kitchen environments. AI
