Let’s think for a minute about exactly how we’ll be
using the ultrasonic sensor. Eddie has two fundamental
parts of his program:
• What to do normally.
When Eddie isn’t seeing the edge of the arena, he’s
simply moving forward so that if he hits the opponent
robot, it will be pushed to the edge (and outside) of the
Sumo ring. Because he’s already moving forward at full
power, there’s no reason to use the ultrasonic sensor as
he does so, which brings us to the other part of his
When Eddie is backing up and turning, he could very
well be passing the opponent robot and/or missing an
opportunity to charge! It’s during this phase of the
program that we’ll make use of the ultrasonic sensor.
Tackling the Program
This will be a relatively complex program compared
to those we’ve worked on in the past. There are many
ways to go about solving a programming problem and,
as usual, I encourage you to explore your own ideas!
That said, here’s what I did.
