hi, Micheal,i start with the board :
a=[0 1;1 0];
P=repmat(a,[4 4]); % it contains 64 cells,
imagesc(P), colormap gray
Now i think you need to set two numbers H A, that each time ( each iteration) H and A change the place with new coordinates (x+1,y+1) but with saving the past state , like you have logical matrix M(64,64) that contains zeros where its free to move and ones otherwise ,and each iteration M is updated .
the RAND function that you use must be like
mod(round(10*(rand(2,1))),8)
As it generates (x,y) such that 1<=x,y<=8
"Making the robot difficult to beat", this condition seems difficult,but i believe its directly related to the Parameters of the Probability Density function {mean,variance, kurtosis, skewness} like the move of the robot is based on pdf's parameters but i must tell you that some strategies do exist on problems like this based on Markov Chains.
during your simulation try to adjust the function 'text' to show where the location of the player/robot is for example you are in the cell (4,5) and the robot is the cell (7,7) .
imagesc(P), colormap gray, hold on
text(4,5,'YOU');
text(7,7,'ROBOT');
I hope its good start
