  • Patent number: 11906944
    Abstract: Methods and systems include ways to implement change analysis of an automated production line including at least one robot. Monitoring a plurality of operating parameters associated with the automated production line including the at least one robot is followed by recording at least one change to the plurality of operating parameters. A notification is then provided identifying the at least one change to the plurality of operating parameters. The notification can include mapping the at least one change onto a graphical representation of the automated production line, thereby identifying a portion of the automated production line affected by the at least one change. As a result, at least one of the operating parameters can be adjusted in response to the notification. An action can also be performed in response to the notification. In this manner, the change analysis can optimize operation of the automated production line.

  • Patent number: 11752632
    Abstract: A system and method for calibrating the position of a machine having a stationary part to a stationary marker. The process first images the machine and the marker, and then identifies a visible part of the machine in the images that has been 3D modeled. The process then calculates a location of the stationary part of the machine using the modeled position of the visible part and the known kinematics and position of the machine. The process then identifies the stationary marker in the images, and establishes a relationship between the stationary marker and the stationary part of the machine, which can be used for calibration purposes. In one embodiment, the machine is a robot and the process is performed by an AR application.

  • Patent number: 11400594
    Abstract: A method and system for programming a path-following robot to perform an operation along a continuous path while accounting for process equipment characteristics. The method eliminates the use of manual teaching cycles. In one example, a dispensing robot is programmed to apply a consistent bead of material, such as adhesive or sealant, along the continuous path. A computer-generated definition of the path, along with a model of dispensing equipment characteristics, are provided to an optimization routine. The optimization routine iteratively calculates robot tool center point path and velocity, and material flow, until an optimum solution is found. The optimized robot motion and dispensing equipment commands are then provided to an augmented reality (AR) system which allows a user to visualize and adjust the operation while viewing an AR simulation of dispensing system actions and a simulated material bead. Other examples include robotic welding or cutting along a continuous path.

  • Patent number: 11396100
    Abstract: A method and system for calibration of an augmented reality (AR) device's position and orientation based on a robot's positional configuration. A conventional visual calibration target is not required for AR device calibration. Instead, the robot itself, in any pose, is used as a three dimensional (3D) calibration target. The AR system is provided with a CAD model of the entire robot to use as a reference frame, and 3D models of the individual robot arms are combined into a single object model based on joint positions known from the robot controller. The 3D surface model of the entire robot in the current pose is then used for visual calibration of the AR system by analyzing images from the AR device camera in comparison to the surface model of the robot in the current pose. The technique is applicable to initial AR device calibration and to ongoing device tracking.

  • Patent number: 11273531
    Abstract: A smart coolant pump for a robotic or computer-controlled machine. The smart pump uses a servo motor rather than a conventional industrial motor such as an induction motor. The smart pump has inherent torque and speed sensing, and a controller integrated with the computer-controlled machine controller. The motor torque/speed sensing and coolant pressure/flow sensing enable immediate detection of any anomalous conditions such as low coolant level or coolant port blockage. The smart pump can be configured to run at a certain speed and provide a specific coolant pressure and flow rate for each machining operation performed at the station, and to run at a very low speed between machining operations. This speed configurability saves energy and allows the pump and coolant to run at lower temperatures compared to conventional constant-speed coolant pumps.

The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. The robot also features kinematics providing redundant inner arm rotation. The arm kinematics, along with the smaller arms, a paint supply line routed through the center of first and third arm joints, and optimized motor conductor routing, dramatically improve near reach flexibility. The improved near reach flexibility in turn allows a smaller spray booth than possible with previous robot architectures.

  • Patent number: 10773383
    Abstract: A method and a system stream robot tool center point position to external processors at high frequency. The method includes the steps of: reading robot joint encoder data using an Interrupt Service Routine in the robot controller; calculating tool center point position based on the encoder data; and sending the calculated position data to a network socket in a high priority task. The method achieves tool center point and/or joint position communication at fast and consistent time intervals, as compared to much longer times for prior art methods. A downstream device, such as a processor or controller for another machine, reads the communicated tool center point and/or joint position data and uses it to control the operations of its own device. High speed motion command streaming from outside processors can be used in a similar way to control the robot.
