Abstract:
Automatic scanning and representing an environment with collision avoidance includes, for example, obtaining a first representation of the environment using a first scanning path, determining a second scanning path based on the first representation of the environment operable to avoid contact with the environment when obtaining a second representation of the environment, obtaining the second representation of the environment based on the second scanning path, and wherein the second representation of the environment is different from the first representation of the environment. The method may be employed in imaging and/or representing a rock wall having a plurality of spaced-apart holes for receiving charges for mining.
Abstract:
A machine that has at least one actuated mechanism is remotely located from a control station. A two way real-time communication link connects the machine location with the control station. An interface at the control station allows an operator to select one or more virtual constraints on operation of the machine when the machine is performing a predetermined function. The virtual constraints are transmitted over the two way real-time communication link to the machine location. The machine has predetermined safety limits that are stored in a controlling device at the machine location. The stored predetermined safety limits are extracted and automatically mapped to the control station using the two way real-time communication link. The controlling device maps the predetermined safety limits to the virtual constraints.
Abstract:
Robot positioning is facilitated by obtaining, for each time of a first sampling schedule, a respective indication of a pose of a camera system of a robot relative to a reference coordinate frame, the respective indication of the pose of the camera system being based on a comparison of multiple three-dimensional images of a scene of an environment, the obtaining providing a plurality of indications of poses of the camera system; obtaining, for each time of a second sampling schedule, a respective indication of a pose of the robot, the obtaining providing a plurality of indications of poses of the robot; and determining, using the plurality of indications of poses of the camera system and the plurality of indications of poses of the robot, an indication of the reference coordinate frame and an indication of a reference point of the camera system relative to pose of the robot.
Abstract:
Three-dimensional visual servoing for positioning a robot in an environment is facilitated. Three-dimensional point cloud data of a scene of the environment is obtained, the scene including a feature. The three-dimensional point cloud data is converted into a two-dimensional image, and a three-dimensional position of the feature is identified based on the two-dimensional image. An indication of the identified three-dimensional position of the feature is then provided.

Abstract:
A teleoperated robot system has a watchdog to determine if the rate of data transmission from a computing device such as a robot controller located in the station used by the operator of the teleoperated robot to the remotely located industrial robot has fallen below a minimum data rate or the time for transmission of data has exceeded a maximum time. Upon the occurrence of either or both of the foregoing, one or more types of corrective action are undertaken to bring the teleoperated robot and the processes performed by the robot.

Abstract:
A machine remotely located from a control station has at least one actuated mechanism. A two way real-time communication link connects the machine location with the control station. A controller at the machine location has program code that includes an instruction which when executed transfers control of the machine from the controller to the control station. The program code can have a task frame associated with the predetermined function performed by the machine with the task frame divided into a first set controlled by the controller and a second set controlled from the control station. The system can also have two or more remotely located control stations only one of which can control the machine at a given time.
Abstract:
One exemplary embodiment is a system comprising an operator input device structured to move in response to operator-applied force and to selectably output feedback force to the operator. A first computing system is structured to receive input from the operator input device and provide an output. A second computing system is structured to receive the output and provide a robot control command subject to a force constraint. An industrial robot system is in operative communication with the second computing system and comprises a robotic arm structured to move in response to the command. The second computing system is structured process the output to impose a force constraint using a dual threshold hysteresis control. The first computing system is structured to apply a feedback force to the operator input device correlated to force associated with the industrial robot system.
