Abstract: A method of determining a path of an autonomous entity through an environment, the method comprising providing a provisional path through a model of the environment from a current location to an intended destination, providing a profile for said autonomous entity, determining a preferred step towards said intended destination based upon said profile and said provisional path, determining a personal space around said autonomous entity and determining whether said preferred step is feasible by considering whether obstructions infringe said personal space.

Abstract: A method of simulating movement of an autonomous entity through an environment, the method comprising providing a provisional path through a model of the environment from a current location to an intended destination, providing a profile for said autonomous entity, determining a preferred step towards said intended destination based upon said profile and said provisional path, determining a personal space around said autonomous entity and determining whether said preferred step is feasible by considering whether obstructions infringe said personal space.
