Stacking In Line Maze Robot

we're working in pairs.basically, he was the one who have us follow that block diagram.He also said something about this being easy since it'll be a sequential circuit

help!!

Here you go razzler.

and the schematics are here



And here is a clone that a student like yourself made; http://www.geocities.com/homemadecpu/aidil/index.htm

Now that would impress the instructor even if it never solved a maze.

the block diagram has been modified it's like this now

robot movement(turn around, left, right, forward)->control logic->counter->memory

the control logic is then specified as the circuit design for the implementation of backtracking to be stored onto the memory

please share your thoughts

thanks ^_^
