Most four wheel bots seem to be ok for the Ocean Odyssey.
Going forward will not work with the light sensor
but going up backwards even with the low angle sensor does work.
After writing a simple program to get all the bots working,
we noticed something that helps make more complicated programs.
Keep other programs that have parts like forward and right in them
and all you have to do to copy parts is drag the parts you want into
another window.
See why the research vehicle is so wobbly? The hook worked to
get the sub.
