  • Patent number: 9110456
    Abstract: A robot machining with a flexible manipulator has an end effector which may either hold the tool to perform the machining or the work piece to be machined. A signal representative of a force applied by said tool to said work piece is used to control either the relative motion between the tool and the work piece to give a controlled material removal rate (CMRR) or the relative position between the tool or the work piece to provide deformation compensation or both CMRR and deformation compensation. A force sensor provides the signal for deformation compensation. For CMRR the signal may be obtained from either a force sensor or the current flowing in the motor of the robot's spindle. The force sensor can be mounted either on the robot or together with either the tool or work piece adjacent to the robot.

  • Patent number: 7643907
    Abstract: The present invention is directed to a method and apparatus for developing a metadata-infused software program for controlling a device, such as a robot. A first library of software segments with metadata and a second library of script documents are provided. A part program wizard uses a script document selected from the second library to display queries on a screen of an interface device. Using input information received in response to the queries, the part program wizard selects and combines software segments from the first library to produce the metadata-infused software program. The metadata identifies the selected software segments and includes statuses of the selected software segments. A graphical representation of the metadata infused software program is displayed on the screen and conveys the statuses of the software segments. A deployment wizard is utilized to teach data points for the metadata-infused software program.

  • Patent number: 7340323
    Abstract: An industrial robot that uses a simulated force vector to allow a work piece held by the robot end effector to be mated with a work piece whose location and orientation is not precisely known to the robot. When the end effector makes contact with the location and orientation in which the other work piece is held the robot provides a velocity command to minimize the force of the contact and also provides a search pattern in all directions and orientations to cause the end effector to bring the work piece it is holding in contact with the other work piece. The search pattern and the velocity command are continued until the two work pieces mate.
