In this paper, we present a grammar-based natural language framework for robot programming, specifically for pick-and-place tasks. Our approach uses a custom dictionary of action words, designed to store together words that share meaning, allowing for easy expansion of the vocabulary by adding more action words from a lexical database. We validate our Natural Language Robot Programming (NLRP) framework through simulation and real-world experimentation, using a Franka Panda robotic arm equipped with a calibrated camera-in-hand and a microphone. Participants were asked to complete a pick-and-place task using verbal commands, which were converted into text using Google's Speech-to-Text API and processed through the NLRP framework to obtain joint space trajectories for the robot. Our results indicate that our approach has a high system usability score. The framework's dictionary can be easily extended without relying on transfer learning or large data sets. In the future, we plan to compare the presented framework with different approaches of human-assisted pick-and-place tasks via a comprehensive user study.

本文提出了一种基于语法的自然语言机器人编程框架，特别用于拾取和放置任务，其方法使用自定义的动作词词典来存储共享意义的单词，通过增加更多的动作词从词汇数据库，轻松扩展词汇量。本文通过模拟和现实世界的实验验证了我们的自然语言机器人编程（NLRP）框架，使用配备了校准相机和麦克风的Franka Panda机器人手臂，并将参与者要求使用口头命令完成拾取和放置任务，该任务经由Google的语音转文本API转换为文本并通过NLRP框架处理，以获取机器人的联合空间轨迹，该方法具有高的系统可用性得分，可以轻松扩展字典而不依赖于转移学习或大型数据集，未来我们计划通过综合用户研究比较所述框架与不同人类辅助拾取和放置任务的方法
