Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a robot to perform a custom real-time action. One of the system comprises a non-real-time control layer configured to compute a sequences of control data and to continually write data elements of the sequence of control data into a real-time streaming input buffer; and a real-time control layer configured to continually read data elements of the sequence of control data from the real-time streaming input buffer and to compute a robot control signal from the read data elements of the sequence of control data at every tick of a real-time control loop.

Streaming input buffer for real-time robotic control

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a robot to perform a custom real-time action. One of the methods comprises receiving, by a real-time robotics control framework, a definition of a custom real-time control function, wherein the definition specifies a plurality of actions and one or more custom reactions; repeatedly executing, by the real-time robotics control framework, the custom real-time control function at each tick of a real-time robotics system driving one or more physical robots, including: obtaining current values of one or more state variables, evaluating the one or more custom reactions specified by the custom real-time control function according to the current values of the one or more state variables, and whenever a custom reaction is satisfied, updating a current action in real time according to the custom reaction that is satisfied, and executing a next tick of the current action.

Real-time robotics control framework

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for overriding an original motion of a robot along a trajectory. The method includes initiating, by a real-time robotics control system, execution of an input trajectory for a robot at a default speed, wherein the input trajectory is a time-parameterized trajectory and specifies a path in an operating environment; before completing execution of the input trajectory, receiving a user input specifying a value of an online speed override factor; in response, generating a phase-parameterized version of the input trajectory using a phase variable; computing, on each real-time control cycle, a target velocity and a target acceleration of the phase-parameterized version of the input trajectory based on the online speed override factor; and causing the robot to transition to the target velocity and the target acceleration while traversing the path in the operating environment.

Online speed override of a trajectory

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a robot to perform a custom real-time action that uses a callback function. One of the methods comprises receiving a definition of a custom real-time control function that specifies a custom callback function, an action, and a custom reaction that references the custom callback function; providing a command to initiate the action; repeatedly executing, by the control layer of the real-time robotics control framework, the custom real-time control function at each tick of a real-time robotics system driving one or more physical robots, including: obtaining current values of one or more state variables, evaluating the custom reaction specified by the custom real-time control function according to the current values of the one or more state variables, and whenever the one or more conditions of the custom reaction are satisfied, invoking the custom callback function.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing online robotic motion planning from pre-generated motion plans. A library of pre-generated motion plans for performing a particular task is maintained. Each pre-generated motion plan comprises a plurality of waypoints and one or more actions. One or more present observations of a robot in a workcell are obtained. The one or more observations are classified. A pre-generated candidate motion plan that matches the labels assigned to the present observations of the robot in the workcell is selected from the library of pre-generated motion plans. The pre-generated candidate motion plan is adapted according to the present observations of the robot in the workcell to generate a final motion plan to be executed by the robot.

Offline robot planning with online adaptation

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a robot to perform a custom real-time action that uses streaming inputs. One of the methods comprises receiving a definition of a custom real-time streaming control function that defines a custom streaming action, wherein the custom streaming action specifies a goal state for a robot in an operating environment; providing a command to initiate the custom streaming action; and repeatedly providing updated goal states for the custom streaming action, wherein the control layer of the framework is configured to execute the custom streaming action including driving the robot toward a most recent goal state at each tick of a real-time robotics control cycle.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing robot plan online adjustment. A method includes receiving an initial plan for performing a particular task with a robot having a sensor. The initial plan defines an initial path having a plurality of waypoints. Each waypoint is associated with a target position and a target velocity. The method includes generating an alternative path from the initial path. Generating an alternative path includes generating a plurality of alternative paths including performing respective modifications to one or more waypoints in the initial plan, evaluating each alternative path according to a simulated total time duration required for the robot to traverse the alternative path, and selecting an alternative path having a total time duration that is less than a total time duration of the initial plan.

Robot plan online adjustment

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling a robot along a goal path. An initial Cartesian path is generated based on a goal path on a workpiece. Dynamic properties of the robot while the robot traverses an initial joint-space trajectory having an initial velocity profile are obtained. An adjusted velocity profile over the Cartesian path is generated based on the obtained dynamic properties. A trajectory is generated by combining the initial Cartesian path and the adjusted velocity profile.
