Goal Images Are Control Targets: Spatially-Grounded Goal-Image Synthesis for Robotic Manipulation

Read the original on arXiv Computer Vision →

Goal images used as control targets in robotic manipulation are not best chosen by general image‑editing quality. The authors show that large proprietary editors, though top on editing‑quality leaderboards, produce poorer control targets than smaller fine‑tuned open models, especially on long‑horizon tasks. They introduce SGE‑Goal, a spatially‑grounded editing framework that predicts edit‑region masks before synthesis, enabling open base models to become the strongest goal generators on CALVIN and nearly as strong on SIMPLER‑Bridge, with superior performance on chained tasks.

Xiaomi-Robotics-U0: Unified Embodied Synthesis with World Foundation Model

arXiv:2607. 11643v1 Announce Type: cross Abstract: Recent foundation image and video generation models offer strong generalization and controllability, but their direct application to embodied scenarios is limited by requirements for multi-view consistency, geometric coherence, and robot embodiment constraints.

Training-Free Interaction-Aligned Visual Token Pruning for Efficient Embodied Manipulation

The paper introduces Interaction‑Aligned Pruning (IAprune), a training‑free method for visual token pruning in embodied manipulation tasks. IAprune jointly decides per‑frame budget and token selection, using semantic‑motion spatial agreement to choose between conservative and aggressive coverage, and applies geometric residual correction to focus on under‑represented boundaries. Experiments on four policies, three simulation benchmarks, and a real‑robot platform show that IAprune matches unpruned performance on LIBERO while achieving up to 1.54× speed‑up and 1.48× acceleration on a real robot.

From Reasoning to Action: Benchmarking Frontier AI Models on LIBERO-10 Robot Manipulation Tasks

The paper introduces a closed‑loop framework to evaluate frontier AI models on the LIBERO‑10 robot manipulation benchmark, allowing models to control a robot via visual inputs, proprioception, and tool calls without task‑specific fine‑tuning. Six models (GPT‑6 Astra, GPT‑6.1 Sol, GPT‑6 Luna, Claude Opus 5, Claude Opus 5.5, Gemini‑4 Argon) were tested across 18 configurations and 1,800 episodes, with GPT‑6 Astra achieving the highest success rate of 44%. Results show that higher reasoning effort generally improves performance, yet benefits vary by model and task, and many models struggle with precise spatial arrangements and complex multi‑step interactions.
