rover planning.py

preliminary code(I got writing pseudocode and it just sort of came out.
a little more complicated than it may need to be right now; think I need
to step it back.  It also has become apparent that just detecting a wall
in front to turn is not a sufficient condition to navigate the maze.  I
know we talked about it before with just the one sensor, but it makes
the logic a lot harder.  I think we should introduce the problem with
two "sensors" (front and right side), to simplify things.  Memory of
where you've been, I think, would also work well
First couple cells of notebook 2 & picture

for some reason, picture isn't calling up correctly.  Need to go now,
will get more finished up tonight.
Changed name to match convention (oops)

01-->02
Fixed small issues in Rover Planning

worked in wakari, not in ipython notebooks. weird.  good, actually; it
made the script need to be a little "tighter"
Wrote mazegen1.py

This creates a maze solvable by right turns only.
Rover planning 1 (right turns)

rover_planning_1.py is the right-turn only simulation on the maze.
currently doesn't use student_func correctly; I've added it at the top
as a stop-gap until I can get it worked out.
functions and basic conditionals introduced

framed with right-turn navigating rover.  has basic "animation" of  a
series of images the student can view.
Second function introduces &, !, and multi-case

Turning left.  Just an introduction, as this won't work.  Next, have
students write edge-follow on the left side, based on previous examples.
Added student-made function.

Want to get student made functions callable by the scripts working
before going too much further.  Comments on current progress, please!
rover_planning_2.py

Forgot to commit. here it is
mazegen2

same deal
Rover_planning.py changes

Should get script better oriented for implementation of the "big finish"
