Assignment for 09/09:

(1) Keep up with the reading.

(2) Watch the following tutorials at 
    http://www.ortop.org/NXT_Tutorial/html/essentials.html:
    -Wait Blocks
    -Light Sensors
    -Viewing Sensors

(3) We will have short (15-20 minute) quiz over the various types of
    NXT-G blocks we have covered.

We wrote our first NXT-G program: we essentially translated our
obstacle avoidance flowchart for humans into (a) a high level
flowchart (using "clouds" to represent high level actions), then a (b)
a detailed flowchart, and finally (c) an NXT-G program.  We noted how
the avoidance procedure went back to the beginning after to restart
from the begining.

We talked briefly about movement blocks and loops.  We tested various
pieces of the program by running fragments as we implemented them.
For instance we initially used a "stop" block in place of the
avoidance routine.  In order to implement the "return to beginning" behavior
we enclosed our program in an infinite loop.

This program is available as avoid.rbt in both share/programs/NXT-G as well
as the L:\examples on the windows server.

We had our first lab today, which is available at

I will post instructions on how to turn in your work in the resources
section of our course page.
