Claim:
1. A method for selecting a trajectory, comprising: using at least one twistlock sensor on a machine to sense a location of a twistlock hole on an object; transmitting said sensed location to a processor to calculate a sensed trajectory for a twistlock to engage said twistlock hole; using at least one operator input sensor to sense an input from an operator moving a joystick to engage said twistlock in said twistlock hole; transmitting said sensed operator input to said processor to calculate an operator trajectory for said twistlock to engage said twistlock hole; comparing said sensed trajectory with said operator trajectory to give said operator trajectory priority over said sensed trajectory if a first difference between said operator trajectory and said sensed trajectory does not exceed a first predetermined limit or if a second difference between said operator trajectory and said sensed trajectory exceeds a second predetermined threshold; determining how much of said sensed trajectory and said operator trajectory will be used to locate said twistlock into said twistlock hole in said object; locating said twistlock in said twistlock hole based on a trajectory determined from said sensed trajectory and said operator trajectory and actuating said twistlock in said twistlock hole.
