A method for selecting a trajectory for container locking uses at least one twistlock sensor on a machine to sense a location of a twist lock hole on an object. The sensed location is transmitted to a processor to calculate a sensed trajectory for a twistlock to engage the twist lock hole. At least one operator input sensor is used to sense an input from an operator moving the twist lock to engage the twist lock hole. The sensed operator input is transmitted to the processor to calculate an operator trajectory for the twist lock to engage the twist lock hole. The sensed trajectory is compared with the operator trajectory to determine which should be used.
