- Abstract: Recent large language models (LLMs) have demonstrated remarkable performance
on a variety of natural language processing (NLP) tasks, leading to intense
excitement about their applicability across various domains. Unfortunately,
recent work has also shown that LLMs are unable to perform accurate reasoning
nor solve planning problems, which may limit their usefulness for
robotics-related tasks. In this work, our central question is whether LLMs are
able to translate goals specified in natural language to a structured planning
language. If so, LLM can act as a natural interface between the planner and
human users; the translated goal can be handed to domain-independent AI
planners that are very effective at planning. Our empirical results on GPT 3.5
variants show that LLMs are much better suited towards translation rather than
planning. We find that LLMs are able to leverage commonsense knowledge and
reasoning to furnish missing details from under-specified goals (as is often
the case in natural language). However, our experiments also reveal that LLMs
can fail to generate goals in tasks that involve numerical or physical (e.g.,
spatial) reasoning, and that LLMs are sensitive to the prompts used. As such,
these models are promising for translation to structured planning languages,
but care should be taken in their use.

Large Language Models (LLMs) possess parametrised knowledge across a wide range of topics, enabling them to leverage the natural language descriptions of planning tasks in their solutions.
We introduce a novel planning method, which leverages the parametrised knowledge of LLMs by using their output as a for Hill-Climbing Search.
Our method outperforms the task success rate of similar systems within a common household environment by 22 percentage points, with consistently executable plans.

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.

We investigate the possibility of grounding high-level tasks, expressed in natural language, to a chosen set of actionable steps.
We find that if pre-trained LMs are large enough and prompted appropriately, they can effectively decompose high-level tasks into low-level plans.
We propose a procedure that conditions on existing demonstrations and semantically translates the plans to admissible actions.
