• Abstract: Recent trends are emerging in the use of Large Language Models (LLMs) as autonomous agents that take actions based on the content of the user text prompt. This study explores the use of fine-tuned Large Language Models (LLMs) for autonomous spacecraft control, using the Kerbal Space Program Differential Games suite (KSPDG) as a testing environment. Traditional Reinforcement Learning (RL) approaches face limitations in this domain due to insufficient simulation capabilities and data. By leveraging LLMs, specifically fine-tuning models like GPT-3.5 and LLaMA, we demonstrate how these models can effectively control spacecraft using language-based inputs and outputs. Our approach integrates real-time mission telemetry into textual prompts processed by the LLM, which then generate control actions via an agent. The results open a discussion about the potential of LLMs for space operations beyond their nominal use for text-related tasks. Future work aims to expand this methodology to other space control tasks and evaluate the performance of different LLM families.

  We introduce DriveMLLM, a benchmark designed to evaluate the spatial understanding capabilities of multimodal large language models (MLLMs) in autonomous driving. DriveMLLM includes 880 front-facing camera images and introduces both absolute and relative spatial reasoning tasks, accompanied by linguistically diverse natural language questions. We evaluate several state-of-the-art MLLMs on DriveMLLM, and our results reveal the limitations of current models in understanding complex spatial relationships in driving contexts.

  Large language models fail to interact with the physical world by generating control sequences properly. Existing LLM-based approaches circumvent this problem by relying on additional pre-defined skills or pre-trained sub-policies. We propose a framework called LLM+A(ffordance) where the LLM serves as both the sub-task planner and the motion controller.

  Large Language Models (LLMs) have recently shown promise as high-level planners for robots. It is often assumed that LLMs do not possess sufficient knowledge to be used for the low-level trajectories themselves. This work investigates if an LLM can directly predict a dense sequence of end-effector poses for manipulation tasks.
