Patent number: 12131529Abstract: A method for performing a task by a robotic device includes mapping a group of task image pixel descriptors associated with a first group of pixels in a task image of a task environment to a group of teaching image pixel descriptors associated with a second group of pixels in a teaching image based on positioning the robotic device within the task environment. The method also includes determining a relative transform between the task image and the teaching image based on mapping the plurality of task image pixel descriptors. The relative transform indicates a change in one or more of points of 3D space between the task image and the teaching image. The method also includes performing the task associated with the set of parameterized behaviors based on updating one or more parameters of a set of parameterized behaviors associated with the teaching image based on determining the relative transform.Type: GrantFiled: January 18, 2023Date of Patent: October 29, 2024Assignee: TOYOTA RESEARCH INSTITUTE, INC.Inventors: Jeremy Ma, Josh Petersen, Umashankar Nagarajan, Michael Laskey, Daniel Helmick, James Borders, Krishna Shankar, Kevin Stone, Max Bajracharya
