Sorry for jumping in at this point and maybe
rehashing what has already been covered.

Possibly some version of the Forth language would
work for you.  I believe you can find Forth that is
running on PIC chips.

Forth will allow you to teach basic programing concepts.
It is certainly different than C, or scripting languages
although it is possible to modify Forth's behaviour to
be more script.like.

Forth operates with nested words and allows immediate
execution of a word ( as well using words in a programmed
process ).  For example, some words might be CCW, CW,
FORWARD, BACKUP,BEEP

180 CCW (cr) would have the robot turn 180 degrees CounterClockwise  
immediately.
20 CW (cr) would have the robot spin clockwise 20 degrees immediately.
Don't like CCW as a command ?  Redefine it as LEFT.
16 FORWARD 180 CCW 19 BACKUP (cr) would have the robot
go forward 16 inches, do a 180, and backup 19 inches.
: BLOOP 16 FORWARD 180 CCW 19 BACKUP ; (cr) would create a new
word called BLOOP.
BLOOP (cr) would then have the robot
go forward 16 inches, do a 180, and backup 19 inches.

Simple once some one demonstrates.   You can show the
same process on a PC with sprites.


There are many free flavors of Forth and it runs on nearly
every processor ever made.

I see that the Rug Warrior Pro uses a 68HC11.  Forth exists
for this processor.
