Abstract: Eye-in-hand cameras have shown promise in enabling greater sample efficiency
and generalization in vision-based robotic manipulation. However, for robotic
imitation, it is still expensive to have a human teleoperator collect large
amounts of expert demonstrations with a real robot. Videos of humans performing
tasks, on the other hand, are much cheaper to collect since they eliminate the
need for expertise in robotic teleoperation and can be quickly captured in a
wide range of scenarios. Therefore, human video demonstrations are a promising
data source for learning generalizable robotic manipulation policies at scale.
In this work, we augment narrow robotic imitation datasets with broad unlabeled
human video demonstrations to greatly enhance the generalization of eye-in-hand
visuomotor policies. Although a clear visual domain gap exists between human
and robot data, our framework does not need to employ any explicit domain
adaptation method, as we leverage the partial observability of eye-in-hand
cameras as well as a simple fixed image masking scheme. On a suite of eight
real-world tasks involving both 3-DoF and 6-DoF robot arm control, our method
improves the success rates of eye-in-hand manipulation policies by 58%
(absolute) on average, enabling robots to generalize to both new environment
configurations and new tasks that are unseen in the robot demonstration data.
