David,
I was looking over the robots & code listed in your "bonus chapters", and I must
confess, I'm a bit disappointed. Maybe I'm missing something, but I'd be
interested to know how these robots have actually done in competition.
Maybe you can help me out, by explaining how this search task (written for
Brain-Bot-ZR1 from Bonus Chapter 2) is designed to work...
------------
/* This task searches for the other
* sumo-bot with a second light sensor*/
task Search()
{
// second highest priority
SetPriority(1);
while(true) // infinite loop - always check for sumo-bots
{
until(LBump<=thresh); // until sensor detects sumo-bot
acquire(ACQUIRE_USER_1) // get control
{
Wait(CALIBRATION); // wait a little
/* if Input Port 1 is less than "thresh" or
* equal to 100*/
if(LBump<=thresh | LBump==100)
{
BL = 1;
BR = 1;
SwitchSTurn(); // if true, go on slow speed and...
speed = 1;
Forward(); // ...attack!
until(LBump==thresh+5); // until sumo-bot goes away
SwitchF(); // stop attacking
speed = 0;
BL = 0;
BR = 0;
PlaySound(SOUND_UP);
}
}
}
}
-----------
I know LBump is the left touch sensor & forward-facing light sensor. And thresh
gets it's value from LBump, when the robot is calibrated. But, I don't see this
task as something that will do a lot of good.
So, how well does it work?
Thanks
Steve

Summed up, some of the concepts presented in this chapter build upon Chapter 6 in Competitive MINDSTORMS, so it's important to understand the concepts in that chapter before reading the (...)

| (...) I finally downloaded and read the bonus chapters as well, and (of course) got confused. I've only been using NQC for a little over a year, so it could be my inexperience, but I knew C for several years prior to using NQC, so I'm not a complete (...)
