20120136564 | Electric Cable Management for a Mobile Machine - A method of managing movement of an electric cable that is configured to provide power to a mobile machine. The method includes determining an initial boundary of an isolation zone in which the cable lies, for a first location of the machine. The initial boundary is divided into a first static boundary and a first dynamic boundary. The first static boundary surrounds a static isolation sub-zone of the isolation zone, and the first dynamic boundary surrounds a dynamic isolation sub-zone of the isolation zone. A second dynamic boundary surrounding the dynamic isolation sub-zone is determined, based on a second location of the machine when the machine moves from the first location to the second location, such that the cable lies within the second dynamic boundary. The first static boundary is maintained when the machine is in the second location. | 05-31-2012 |
20130268138 | High Availability For Autonomous Machine Control System - A control system for a work site including an autonomous machine includes a central control system that includes a cluster of servers configured to execute an autonomous control server application on exactly one of the cluster of servers. A RAID system is in communication with the cluster of servers. A first switch interconnects a first network with the cluster of servers, and a second switch interconnects a second network with the cluster of servers. A UPS system interconnects a power source with the cluster of servers, the RAID system, and the first and second switches. The machine control system is communicatively coupled with the central control system via a wireless network and one of the first and second networks. The machine control system transmits machine position information to the autonomous control server application and receives a route plan generated by the autonomous control server application. | 10-10-2013 |
20130311153 | VIRTUAL ENVIRONMENT AND METHOD FOR SORTING AMONG POTENTIAL ROUTE PLANS FOR OPERATING AUTONOMOUS MACHINE AT WORK SITE - A method for sorting among a plurality of potential route plans for operating an autonomous ground based machine includes a step of creating a virtual model of a terrain of a work site. A first virtual lane having at least one measurable lane constraint is created within the virtual model. A first virtual machine footprint is created and has a first virtual movement profile corresponding to an actual autonomous movement profile of the autonomous machine. The first virtual machine footprint is moved from a starting position along the first virtual lane to an ending position according to the first virtual movement profile. During the moving step, the first virtual machine footprint is compared to the at least one measurable lane constraint. The first proposed route plan is then designated as either viable or unacceptable based on the comparison. | 11-21-2013 |
