In this paper, we study the problem of enabling a vision-based robotic manipulation system to generalize to novel tasks, a long-standing challenge in robot learning. We approach the challenge from an imitation learning perspective, aiming to study how scaling and broadening the data collected can facilitate such generalization. To that end, we develop an interactive and flexible imitation learning system that can learn from both demonstrations and interventions and can be conditioned on different forms of information that convey the task, including pre-trained embeddings of natural language or videos of humans performing the task. When scaling data collection on a real robot to more than 100 distinct tasks, we find that this system can perform 24 unseen manipulation tasks with an average success rate of 44%, without any robot demonstrations for those tasks.

本文旨在通过模仿学习的角度研究如何通过扩大数据采集并建立交互灵活的学习系统来促进基于视觉的机器人操作系统向新任务的泛化，当扩展真实机器人的数据采集到100个不同的任务时，我们发现此系统可以实现24个未见过的操作任务，平均成功率为44%。
