  • Patent number: 10570582
    Abstract: A machine includes a power generation system; a propulsion system; a work implement coupled to a body of the machine via a linkage that includes at least one actuator; a perception system configured to generate a signal that is indicative of a position of the machine relative to a material receptacle; and a controller operatively coupled to the perception system, the propulsion system, the power generation system, and the at least one actuator. The controller is configured to receive the signal from the perception system, determine a location of the work implement relative to the material receptacle based at least in part on the signal from the perception system, and actuate at least one of the propulsion system, the power generation system, and the at least one actuator based on the determined location of the work implement relative to the material receptacle.

  • Patent number: 9773175
    Abstract: A system for tracking a position of a cable attached between a power source and a machine in a worksite is disclosed. The cable is further coupled to a guiding device located in the worksite between the power source and the machine. The system includes a perception module disposed on the machine to detect a location of the guiding device. The system further includes a controller disposed to be in communication with the perception module. The controller determines the location of the guiding device with respect to a location of the machine and determines a distance between the guiding device and the machine. The controller further compares the distance with a first threshold distance and a second threshold distance and generates a warning if the distance is greater than the first threshold distance or smaller than the second threshold distance.

  • Publication number: 20170073935
    Abstract: A system for evaluating a position of a target zone relative to a path of a material engaging work implement includes a rotatable implement system, an implement system pose sensor, and a target pose sensor. A controller determines a current pose of a portion of the implement system, determines a first pose of the target zone, determines a plurality of potential paths for moving the work implement to the first pose, and generates an alert command if a kinematic model and desired operating characteristics do not permit movement of the work implement to the first pose.

  • Publication number: 20170073925
    Abstract: A system for controlling movement of a work implement of a machine between a dump location and a plurality of dig locations includes a rotatable implement system, and an implement system pose sensor. A controller is configured to store first dig signals from the implement system pose sensor indicative of a first dig location, store second dig signals from the implement system pose sensor indicative of a second dig location spaced from the first dig location and store a dump location. The controller is further configured to generate command signals to move the work implement from the first dig location to the dump location, generate command signals to dump a load of material carried by the work implement at the dump location, and generate command signals to move the work implement from the dump location to the second dig location.

  • Patent number: 9454147
    Abstract: A system for setting a dump height of a material engaging work implement above a dump body includes a rotatable implement system, an implement system pose sensor, and a bed height sensor. A controller determines an initial bed height, determines an initial dump height, generates a command based upon the pose of the work implement, and determines a subsequent dump height higher than the initial dump height. The controller is further configured to position the work implement at the subsequent dump height, determine a further subsequent dump height higher than the subsequent dump height, and position the work implement at the further subsequent dump height over the dump body.

  • Patent number: 6548982
    Abstract: A robotic vehicle capable of traveling over various terrain and traversing obstacles. In one embodiment, the vehicle includes a cylindrical body having two or more drive wheels coupled to the ends thereof. The wheels are selectively powered to propel the vehicle. The vehicle may further include a spring member which may be deflected to a first, stored position from a second, extended position. The spring member may be quickly released from the first, stored position such that it strikes the terrain with sufficient force to lift and propel the vehicle over or onto a proximate obstacle or object. Robotic vehicles of the present invention may also include one or more sensing devices operable to collect information. Electronics may further permit autonomous, semi-autonomous, and/or remote control of the vehicle. In still other embodiments, the robotic vehicle forms part of a multi-robot surveillance team.
