Patent number: 11787048Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing robot planning using a process definition graph. One of the methods includes receiving an initial underconstrained process definition graph for one or more robots, wherein the process definition graph is a directed acyclic graph having constraint nodes and action nodes. A plurality of transformers are repeatedly applied to the initial process definition graph, wherein each application of a transformer generates a respective modified process definition graph according to the constraint nodes of the process definition graph, wherein applying the plurality of transformers generates a schedule that specifies which of the one or more robots are to perform which of one or more actions represented by actions nodes according to constraints imposed by the constraint nodes in the process definition graph.Type: GrantFiled: August 27, 2020Date of Patent: October 17, 2023Assignee: Intrinsic Innovation LLCInventors: Ryan Butterfoss, Keegan Go, Stoyan Gaydarov

Patent number: 11745345Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for planning by work volumes to avoid conflicts. One of the methods includes receiving a process definition graph for a robot that includes action nodes, wherein the action nodes include (1) transition nodes that represent a motion to be taken by the robot from a respective start location to an end location and (2) task nodes that represent a particular task to be performed by the robot at a particular task location. An initial modified process definition graph that ignores one or more conflicts between respective transition nodes as well as one or more conflicts between respective transition nodes and task nodes is generated from the process definition graph. A refined process definition graph that ignores conflicts between transition nodes and recognizes conflicts between transition nodes and task nodes is generated from the initial modified process definition graph.Type: GrantFiled: August 27, 2020Date of Patent: September 5, 2023Assignee: Intrinsic Innovation LLCInventors: Jean-Francois Dupuis, Keegan Go, Stoyan Gaydarov

Patent number: 11577392Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for optimizing a plan for one or more robots using a process definition graph. One of the methods includes receiving a process definition graph for a robot, the process definition graph having a plurality of action nodes. One or more of the action nodes are motion nodes that represent a motion to be taken by the robot from a respective start location to an end location. It is determined that a motion node satisfies one or more splitting criteria, and in response to determining that the motion node satisfies the one or more splitting criteria, the process definition graph is modified. Modifying the process definition graph includes splitting the motion node into two or more separate motion nodes whose respective paths can be scheduled independently.Type: GrantFiled: August 28, 2020Date of Patent: February 14, 2023Assignee: Intrinsic Innovation LLCInventors: Jean-Francois Dupuis, Keegan Go, Stoyan Gaydarov

Patent number: 11256240Abstract: Disclosed herein is a worksite automation process that involves: generating a first sequence of tasks to build the product according to a model. The process further involves causing one or more robotic devices to build the product by beginning to execute the first sequence of tasks. Further, during the execution of the first sequence of tasks, performing a buildability analysis to determine a feasibility of completing the product by executing the first sequence of tasks. Based on the analysis, determining that it is not feasible to complete the product by executing the first sequence of tasks, and in response, generating a second sequence of tasks to complete the product according to the model. Then, causing the one or more robotic devices to continue building the product by beginning to execute the second sequence of tasks.Type: GrantFiled: December 6, 2019Date of Patent: February 22, 2022Assignee: Intrinsic Innovation LLCInventors: Kendra Byrne, Eli Reekmans, Stoyan Gaydarov, Marek Michalowski, Michael Beardsworth, Ryan Butterfoss, Ytai Ben-Tsvi
