Abstract

Robotic manipulation in unstructured environments requires reliable execution under diverse conditions, yet many state‑of‑the‑art systems still struggle with high‑dimensional action spaces, sparse rewards, and slow generalization beyond carefully curated training scenarios. We study these limitations through the example of grasping in space environments. We learn control policies directly in a learned latent manifold that fuses (grammarizes) multiple modalities into a structured representation for policy decision‑making. Building on GPU‑accelerated physics simulation , we instantiate a set of single‑shot manipulation tasks and achieve over 95% task success with Soft Actor‑Critic (SAC)‑based reinforcement learning in less than 1M environment steps, under continuously varying grasping conditions from step 1. This empirically shows faster convergence than representative state‑of‑the‑art visual baselines under the same open‑loop single‑shot conditions. Our analysis indicates that explicitly reasoning in latent space yields more sample‑efficient learning and markedly improved robustness to novel object and gripper geometries, environmental clutter, and sensor configurations compared to standard baselines. These mark a substantial addition to the space-based robotic grasping paradigm. At the same time, we identify remaining limitations and outline directions towards fully adaptive and generalizable grasping in the extreme conditions of space.
