vacuum cleaner in prolog programming

[agentpintar]

im in process of building a small robotic agent that will clean up a house. Assuming that the robot is equipped with a sensor that will tell it is over any dirt, and a vacuum cleaner that can be used to suck up dirt.In addition to be able to suck uo dirt, the agent can move forward one step or turn right 90 degree. The agent can move around a room (is a 3 * 3 grid) and always starts in square (0,0) facing north.

the agent can receive a percept dirt (signing that there is dirt beneath it), or null (indicating clean). It can perform any one of three possible actions: FORWARD, SUCK, or TURN. the goal is to traverse the room continually searching for and removing dirt.

i would like to know the way the vacuum can move continuelly move in the room...thanks
