What it does

  • Provides code for grasping, manipulation, mapping, navigation, and LLM agents on the Stretch 3 robot.
  • Includes text-to-speech and speech-to-text, plus visualization and debugging tools.
  • Offers a language-directed pick and place demo where the robot picks up an object and places it in a receptacle described in words.
  • Runs a server on the Stretch robot while the AI workloads run on a separate GPU computer over WiFi.
  • Supports embodied question answering, where the robot explores its environment to answer user questions.
  • Includes learning-from-demonstration support, which requires an optional dexterous teleop kit.
