Data-driven approaches to solving robotic tasks have gained a lot of traction in recent years. However, most existing policies are trained on large-scale datasets collected in curated lab settings. If we aim to deploy these models in unstructured visual environments like people's homes, they will be unable to cope with the mismatch in data distribution. In such light, we present the first systematic effort in collecting a large dataset for robotic grasping in homes. First, to scale and parallelize data collection, we built a low cost mobile manipulator assembled for under 3K USD. Second, data collected using low cost robots suffer from noisy labels due to imperfect execution and calibration errors. To handle this, we develop a framework which factors out the noise as a latent variable. Our model is trained on 28K grasps collected in several houses under an array of different environmental conditions. We evaluate our models by physically executing grasps on a collection of novel objects in multiple unseen homes. The models trained with our home dataset showed a marked improvement of 43.7% over a baseline model trained with data collected in lab. Our architecture which explicitly models the latent noise in the dataset also performed 10% better than one that did not factor out the noise. We hope this effort inspires the robotics community to look outside the lab and embrace learning based approaches to handle inaccurate cheap robots.

研究表明，大多数基于数据驱动的机器人任务都是在实验室环境中收集的大规模数据集上进行训练的，该论文提出了在人们的家庭环境中使用低成本机器人手动搬运收集数据的方法，并开发了一种框架来处理数据中的噪音标签。该模型在采集了28,000次抓取数据并针对不同环境条件进行物理性能测试后，相较于实验室收集的数据，展现了明显的43.7%的改善，该模型还比其他模型表现10%更好。
