Testing Plow Adjustments
A simple program to make each SumoBot go forward should be used to test the plows.
This eliminates the possibility of IR object detectors interfering with the SumoBot's
forward motion. For example, if one of the SumoBot's IR detectors briefly misses its
opponent, the SumoBot will hesitate and might not be going full speed when the two
SumoBots collide. It's true that this will also happen during a match, but during practice
it's best to test only one variable at a time, in this case, the plow adjustment.

Label both your SumoBots so that you can distinguish them. If A and B aren't
interesting enough labels, some searching on the Internet will yield names of
sumo legends as well as present stars.

Load the program into both SumoBots.
Place both SumoBots facing each other as shown in Figure 1-3.
