  • Patent number: 11912547
    Abstract: A system includes a platform to support a vehicle on a first side of the platform and a passive motion device arranged on a second side of the platform, opposite the first side, to move upon actuation. A mechanical actuator actuates the passive motion device based on movement of one or more wheels of the vehicle to change a position of the vehicle. The position of the vehicle relative to the platform is unchanged and the passive motion device is actuated by only the movement of the one or more wheels of the vehicle to change the position of the vehicle.

  • Publication number: 20230145508
    Abstract: A partially assembled vehicle that autonomously completes its own assembly, including a chassis, wheels that are rotationally coupled to the chassis, a drive system mounted on the chassis and in operational communication with the wheels, a navigation system, a central platform controller, and a position determining system. Added thereto is a safety sensor guidance system and a controller circuit programmed to begin a temporary takeover of the central platform controller, responsive to an external fleet control. The temporary takeover including the steps of identifying a plurality of assembly stations that the partially assembled vehicle must visit to complete its own assembly; constructing a sequence in which to visit each of the plurality of assembly stations; and commanding the drive system to propel and steer the partially assembled vehicle through the sequence of the plurality of assembly stations, responsive to sensor input from the safety sensor guidance system.

  • Patent number: 10933933
    Abstract: An autonomous vehicle guidance system enables a partially assembled battery-electric vehicle (BEV) to be guided through an assembly process with the temporary addition of a sensor skid. The partially assembled BEV includes a vehicle body, a vehicle controller coupled to the vehicle body, a battery electrically coupled to the vehicle controller, a sensor skid configured to be coupled under the vehicle body of the BEV. The sensor skid is configured to guide the BEV through an assembly process. The sensor skid includes a skid body configured to be coupled under the vehicle body of the BEV and a plurality of sensors coupled to the skid body. The sensor skid includes a skid controller in communication with the sensors and the vehicle controller. The skid controller is coupled to the sensor skid.

  • Publication number: 20150336271
    Abstract: A system for assembling a first component and a second component comprises a support operatively supporting the first component without any fixtures, a vision system configured to view the supported first component and the second component and determine the locations thereof, a robotic system configured to move and position the second component relative to the first component, and a controller operatively connected to the vision system and to the robotic system and operable to control the robotic system to position the second component relative to the first component based on the locations determined by the vision system. Various methods of assembling the first component and the second component are provided to create a process joint prior to creation of a structural joint in a subsequent assembly operation.

  • Patent number: 8606421
    Abstract: Methods of forecasting and modulating energy consumption at a production facility are provided. The amounts of energy consumed during production and non-production times are used to obtain highly accurate hourly energy use rates for different energy use activities which are used to estimate the amount of energy that will be consumed during a subsequent time period. The forecasting and modulating methods provide a more tailored estimate of energy usage that prevents the unnecessary expense of using on-demand energy without the benefit of a pre-purchased or pre-reserved discount. The forecasting and modulating methods also help prevent overestimation of the amount of energy used.
