Glimpse of Manipulation Behaviors
We show manipulation results for different kitchen/office tasks illustrating navigation (teleoperated) followed by manipulation (autonomous) of different objects in their natural scenes. The autonomous manipulation is with a single goal-conditioned policy, with subsequent goals shown as inset in the top right.
Qualitative Results for Residual Policy Executions
We characterize different levels of generalization based on the small amount of robot training data and show robot evaluations for each level. The videos are from a third person camera and show the robot executing different tasks. The corresponding goal images are shown as an inset at the top right.
Type Generalization (TG)
Here we generalize to completely unseen object types in unseen scenes. For example, unseen object types like jackets, microwaves, waffle makers, armoires, refrigerators etc.
Compositional Generalization (CG)
In CG, we generalize to unseen activity-object type combinations. For example, we have seen opening a room's door in the robot data, but not closing a room's door. Similarly, we have closing a cabinet door, flipping close a spice box, closing a trash box etc.
Standard Generalization (G)
In G, we evaluate unseen object instance in seen and unseen scenes. For example, only a red mug is seen in the context of a pushing activity in training, and we generalize to pushing motions for green, and purple mugs of different shapes and textures.
Mild Generalization (MG)
This involves generalizing among unseen configurations (i.e. position and orientation variations) for seen object instnaces, along with mild variations in the scene like lighting changes and camera pose changes.
Detailed Results for Track Prediction and Robot Execution
We show results categorized by different levels of Generalization. Note that the generalization level is for robot execution as described in the paper. The track prediction model is only trained on web videos. The videos and images are from the robot's on-board RealSense camera.

Type Generalization (TG)
Failures
We can see that some common failure cases of our approach include incorrect grasps of objects, getting stuck while trying to articulate large/heavy objects like fridge doors, and toppling smaller objects like bottles
