Step 2 - Test the Roaming with IR Object Detection Program
Chapter 7, Activity #5 from Robotics with the Boe-Bot introduces a high performance
version of roaming with IR. This program checks for an object between each servo pulse
(that's around 40 times per second), so the Boe-Bot is very responsive when it detects
obstacles. You will be modifying this program, so go ahead and do a refresher on how it
works. It's also important to make sure the original program works with your circuit
before moving on to the other modifications.
Step 3 - Modify the Program so that You Can Control Roaming Speed
Variables can be used to control a variety of Boe-Bot behaviors. Among other things,
these variables can tell the Boe-Bot how fast to go (this step) and what task to perform
(next step). Just a few examples of conditions that can be used to change these variables
are:
