Learning Language-Conditioned Robot Behavior from Offline Data and Crowd-Sourced Annotation

Nair, Suraj, Mitchell, Eric, Chen, Kevin et al.

Understand

We study the problem of learning a range of vision-based manipulation tasks from a large offline dataset of robot interaction.

  • In order to accomplish this, humans need easy and effective ways of specifying tasks to the robot.
  • Goal images are one popular form of task specification, as they are already grounded in the robot's observation space.
  • However, goal images also have a number of drawbacks: they are inconvenient for humans to provide, they can over-specify the desired behavior leading to a sparse reward signal, or under-specify task information in the case of non-goal reaching tasks.
