General-purpose robots coexisting with humans in their environment must learn to relate human language to their perceptions and actions to be useful in a range of daily tasks. Moreover, they need to acquire a diverse repertoire of general-purpose skills that allow composing long-horizon tasks by following unconstrained language instructions. In this paper, we present CALVIN (Composing Actions from Language and Vision), an open-source simulated benchmark to learn long-horizon language-conditioned tasks. Our aim is to make it possible to develop agents that can solve many robotic manipulation tasks over a long horizon, from onboard sensors, and specified only via human language. CALVIN tasks are more complex in terms of sequence length, action space, and language than existing vision-and-language task datasets and supports flexible specification of sensor suites. We evaluate the agents in zero-shot to novel language instructions and to novel environments and objects. We show that a baseline model based on multi-context imitation learning performs poorly on CALVIN, suggesting that there is significant room for developing innovative agents that learn to relate human language to their world models with this benchmark.

本文提出了CALVIN（通过语言和视觉组合动作）这一开放源代码数据集，目的是让机器人代理能够通过追踪无限制的语言指令来解决许多长期性的机器人操纵任务，并支持传感器套件的灵活规定。在零-shot条件下，实验证明基于多环境下的学习的基线模型在CALVIN任务中表现不佳，因此本数据集对开发学习如何将人类语言与世界模型相关联的创新代理具有重要意义。
