Problem 3: Consider the ICT bot in this 3*3 grid.

Y X
1 2 3
1 S    
2      
3 *   E

S is the location where the robot starts.
E is the end location where the robot must find * and carry to E.

  • The robot can perform two actions: move and retrieve_star.
  • It can move in 4 directions 1 adjacent cell at a time, from (x,y) to (x+1,y), (x-1,y),(x,y+1), and (x,y-1) as long as it remains on the 3*3 grid.
  • Upon each grid, the robot will receive the signal from its sensor if * is in the current grid or not. If * is in the current grid, it can retrieve * using the retrieve_star command.

1) Design a classical representation for the current planning problem.
