MESA is an evaluation framework that precisely measures language‑conditioned policy generalization in robotics. It offers five evaluation suites that separate in‑distribution performance from four axes of generalization—spatial configuration, object instance, object category, and subtask composition—allowing researchers to pinpoint why policies fail. The authors also introduce MESA‑Gen, a task and demonstration generation pipeline, and release two benchmark suites: a single‑arm MESA and BiMESA for bimanual generalization, with baseline results showing current models achieve only about 50% success, indicating significant room for improvement.

RoboSPA is a large-scale robotic manipulation dataset and benchmark designed to evaluate Vision‑Language‑Action models on fine‑grained spatial reasoning and long‑horizon procedural planning. It contains 10 task categories, 56 base tasks, and 280 variants across five difficulty levels, with 527K trajectories collected from multiple embodiments and scenes. The benchmark introduces diagnostic metrics beyond binary success, revealing that current VLA models struggle with complex spatial relations, precise execution, and memory‑intensive planning.
arXiv:2604. 09860v4 Announce Type: replace-cross Abstract: The pursuit of general-purpose robotics has yielded impressive foundation models, yet simulation-based benchmarking remains a bottleneck due to rapid performance saturation and a lack of true generalization testing.
RoboGene is an agentic framework designed to generate diverse and informative manipulation tasks for single-arm, dual-arm, and mobile robots. It employs diversity-driven sampling, agentic self-reflection for task quality assessment, and human-verified feedback memory to validate and refine tasks. The framework produced 18,000 real-world trajectories and introduced new metrics for task feasibility and diversity, outperforming models like GPT‑4o and Gemini 2.5 Pro in training VLA models that achieve higher success rates and stronger generalization.

arXiv:2607. 05377v1 Announce Type: cross Abstract: While recent Vision-Language-Action (VLA) models show promise toward generalist manipulation policies, they struggle with long-horizon tasks due to their Markovian nature-relying solely on current observations.
arXiv:2601. 20334v2 Announce Type: replace-cross Abstract: Robotic manipulation has increasingly adopted vision-language-action (VLA) models, which achieve strong performance but typically require task-specific demonstrations and fine-tuning, and often generalize poorly under domain shift.
BURGER is a benchmark for evaluating vision‑language‑action models on robotic drawing tasks. It provides a scalable, prompt‑driven pipeline that generates continuous drawing trajectories in both simulation and the real world, with 28,200 simulated demonstrations across 282 tasks. The benchmark enables fine‑grained analysis of language grounding, spatial composition, and action generation, revealing distinct failure patterns among five representative VLA models and demonstrating that some models can generalize to unseen compositions and scale with task diversity.
BURGER is a language‑conditioned robotic drawing benchmark that uses a prompt‑driven pipeline to generate continuous drawing trajectories in both simulation and the real world. The benchmark provides 28,200 simulated demonstrations across 282 tasks, allowing evaluation of vision‑language‑action models on data scale, language grounding, and multimodal behavior. Experiments show that some models improve with more diverse data, capture complex drawing behaviors, and generalize to unseen compositions, with a trained policy successfully deployed on a Franka Panda arm.
