  • Publication number: 20260094437
    Abstract: Systems and methods are provided for generating task progress values from digital video. A temporal sequence of frames of a digital video is shuffled to generate a shuffled plurality of video frames. A reordering input prompt is assembled to include data indicative of one or more tasks depicted being performed in the digital video and the shuffled plurality of video frames. The reordering input prompt is processed using a generative model to generate data indicative of one or more task progress values corresponding to one or more of the shuffled plurality of video frames. Each task progress value represents an amount of progress towards accomplishing the one or more tasks that is depicted in the corresponding video frame. The generated task progress values may be used for various purposes, such as training a separate model, including a robot control policy, or for data quality control.

  • Publication number: 20250213980
    Abstract: In a method for collision event determination, a first estimated trajectory that a target object is expected to follow during a next movement period is obtained. A second estimated trajectory that a collision object is expected to follow during the next movement period is obtained. A spatial positional relationship between the first estimated trajectory and the second estimated trajectory is determined to satisfy a reference collision condition. Based on the determination that the spatial positional relationship between the first estimated trajectory and the second estimated trajectory satisfies the reference collision condition, a candidate collision space that indicates a space through which the target object is not allowed to move is determined. A collision event is determined to occur between the target object and the collision object when a plurality of candidate object positions on the first estimated trajectory include a target object position in the candidate collision space.

    Abstract: Some implementations related to using a large language model (LLM) in generating (and potentially refining) a plan for the execution of a long-horizon robotic task. Various implementations include processing, using the LLM, a free-form natural language instruction and textual feedback to generate LLM output. In many implementations, the free-form natural language instruction describes the robotic task. In additional or alternative implementations, the textual feedback can include task-specific feedback, passive scene description feedback, active scene description feedback, one or more additional or alternative types of environmental feedback, and/or combinations thereof. In some implementations, the system can select one or more robotic skills to perform based on the LLM output.
