receive initial state data from one of more of the plurality of transporting vessels within the region;

receive one or more goals to relocate the relocatable transporting vessel from the start location to the destination location, wherein the goal requests whether to leave a given location within the cluster empty or occupied by one of the plurality of transporting vessels; and

perform a search to determine possible sequences of states that can be implemented to relocate the relocatable transporting vessel from the start location to the destination location.

2. A system as claimed in claim 1 , wherein the motion control system is configured to address a number of the plurality of the transporting vessels and provide respective instructions thereto in order to affect translation of the relocatable transporting vessel within the cluster in accordance with the determined path.

3. A system as claimed in claim 2 , wherein the number of the plurality of transporting vessels comprises:

the relocatable transporting vessel.

4. A system as claimed in claim 1 , wherein the relocatable transporting vessel is configured to translate laterally within the cluster.

another relocatable transporting vessel of the plurality of transporting vessels configured to be relocatable within the cluster in response to another instruction; wherein:

the motion control system is configured to determine another path from another start location of the other relocatable transporting vessel within the cluster to another destination location within the cluster; and

the motion control system is configured to execute movement of the other relocatable transporting vessel within the cluster using the determined other path.

14. A system as claimed in claim 1 , wherein the motion control system is configured to determine a plurality of sequences of states in respect of at least part of the cluster and corresponding to a tree of states having a predetermined depth.

15. A system as claimed in claim 14 , wherein the motion control system is configured to analyse the plurality of sequences of states and to calculate a cost in respect of each sequence of states of the plurality of sequence of states.

16. A method of relocating a transporting vessel within a plurality of transporting vessels arranged as a three-dimensional cluster of transporting vessels, the plurality of transporting vessels being respectively addressable and the cluster having a self-reconfigurable physical topology, the method comprising:

determining a path from a start location of a relocatable transporting vessel within the cluster to a destination location within the cluster via a motion control system; and

executing movement of the relocatable transporting vessel within the cluster using the determined path;

notionally sub-dividing the cluster into regions;

for the region of the cluster in which the start location of the relocatable transporting vessel and the destination location are located:

receiving initial state data from one or more of the plurality of transporting vessels within the region;

receiving one or more goals to relocate the relocatable transporting vessel from the start location to the destination location, wherein the goal requests whether to leave a given location within the cluster empty or occupied by one of the plurality of transporting vessels; and

performing a search to determine possible sequences of states that can be implemented to relocate the relocatable transporting vessel from the start location to the destination location.
