A robot, who was soon named LeRoy Roboto, was built.


Using PILOT 4

the robot was programmed to go in a square.

Going on to INVENTOR we practiced connecting the program steps with wires.
Use space bar to change between select arrow and wire tool.
TAB will rotate through select, wire, text as will show tools window.  HELP will show information.

One of the teachers suggested zig zag.  It was immediately programmed.
Another teacher suggested making a model of a mine and having a robot
find its was through and report back data on distance, etc.

Most programming is done in PROGRAMMER in INVENTOR.
Level 4 has all the program elements.  Starting on level 1 and working up is a way to get familiar
with the various out puts inputs, and conditionals.
The above program had the robot, LeRoy Roboto, go forward when the touch sensor on input 1
was released and stop when the touch sensor was pushed.

The piano player was used to play music on the RCX.  This program uses the music saved in the red scroll.
Note the program uses multi-tasking.
The loop of go forward until dark, back up, turn and repeat continues while at the same time as the music plays.
The robot stayed on the white paper.
When it got to the darker edge it backed up turned and when forward until it came to the edge of the paper again.

Programming can also be done in INVESTIGATOR.  With that level of programming data logging can be done.
It can be used for doing science experiments.  There is a place for writing the journal and uploading and displaying data form sensors.
When the programming is complete the work can be displayed as a side show or web page.
See the web pages done on Valentine's day at Big Creek High.

Note: The programs STAY ON WHITE and ZIG ZAG were written while in INVESTIGATOR.
