  • Sensor feedback control for automated bucket loading
    Patent number: 5941921
    Abstract: Automated bucking loading is achieved through the use of sensor feedback provided by pressure and extension sensors on hydraulic cylinder(s) to control the trajectory of the bucket to be loaded by a computer algorithm. Additional sensors may be used to provide further control of the loading cycle and of the vehicle operation. The structure and steps can be integrated with existing machinery or used on new loaders equipped with suitable control interfaces capable of taking computerized control of the vehicle's actions.
