"No, to the Right" -- Online Language Corrections for Robotic Manipulation via Shared Autonomy

Cui, Yuchen, Karamcheti, Siddharth, Palleti, Raj et al.

Understand

Systems for language-guided human-robot interaction must satisfy two key desiderata for broad adoption: adaptivity and learning efficiency.

  • Unfortunately, existing instruction-following agents cannot adapt, lacking the ability to incorporate online natural language supervision, and even if they could, require hundreds of demonstrations to learn even simple policies.
  • In this work, we address these problems by presenting Language-Informed Latent Actions with Corrections (LILAC), a framework for incorporating and adapting to natural language corrections - "to the right," or "no, towards the book" - online, during execution.
  • We explore rich manipulation domains within a shared autonomy paradigm.
