MolmoAct: Action Reasoning Models That Can Reason in Space

ICRA 2026poster

Reasoning is essential for purposeful action, yet most robotic foundation models map perception and instructions directly to control, limiting adaptability, generalization, and semantic grounding. We introduce Action Reasoning Models (ARMs), which integrate perception, planning, and control through …

MolmoSpaces: Large-Scale Open Ecosystem for Robot Manipulation and Navigation

RSS 2026poster

Deploying robots at scale demands robustness to the long tail of everyday situations. The countless variations in scene layout, object geometry, and task specifications that characterize real environments are vast and underrepresented in existing robot benchmarks. Measuring this level of generalizat…

RoboEval: Where Robotic Manipulation Meets Structured and Scalable Evaluation

ICRA 2026poster

We introduce RoboEval, a structured evaluation framework and benchmark for robotic manipulation that augments binary success with principled behavioral and outcome metrics. Existing evaluations often collapse performance into outcome counts, masking differences in execution quality and obscuring fai…

AHA: A Vision-Language-Model for Detecting and Reasoning Over Failures in Robotic Manipulation

ICLR 2025poster

Robotic manipulation in open-world settings requires not only task execution but also the ability to detect and learn from failures. While recent advances in vision-language models (VLMs) and large language models (LLMs) have improved robots' spatial reasoning and problem-solving abilities, they sti…

SAM2Act: Integrating Visual Foundation Model with A Memory Architecture for Robotic Manipulation

ICML 2025poster

Robotic manipulation systems operating in diverse, dynamic environments must exhibit three critical abilities: multitask interaction, generalization to unseen scenarios, and spatial memory. While significant progress has been made in robotic manipulation, existing approaches often fall short in gene…

Manipulate-Anything: Automating Real-World Robots using Vision-Language Models

CoRL 2024poster

Large-scale endeavors like RT-1 and widespread community efforts such as Open-X-Embodiment have contributed to growing the scale of robot demonstration data. However, there is still an opportunity to improve the quality, quantity, and diversity of robot demonstration data. Although vision-language m…

RoboPoint: A Vision-Language Model for Spatial Affordance Prediction in Robotics

CoRL 2024poster

From rearranging objects on a table to putting groceries into shelves, robots must plan precise action points to perform tasks accurately and reliably. In spite of the recent adoption of vision language models (VLMs) to control robot behavior, VLMs struggle to precisely articulate robot actions usin…

THE COLOSSEUM: A Benchmark for Evaluating Generalization for Robotic Manipulation

RSS 2024poster

To realize effective large-scale, real-world robotic applications, we must evaluate how well our robot policies adapt to changes in environmental conditions. Unfortunately, a majority of studies evaluate robot performance in environments closely resembling or even identical to the training setup. We…
