\b;Exercise

Instruct the bot to find all the \l;blue crosses\u object\waypoint; on the ground, but do not get too close to the \l;mines\u object\mine;. When the bot passes over a cross, it disappears. Here is the general principle:
|
||
|
|
|
||
|
|
Repeat forever:
|
||
|
|
o Look for a mine
|
||
|
|
o If a mine has been found, calculate the opposite direction
|
||
|
|
o Look for a cross
|
||
|
|
o If nothing has been found, stop the program
|
||
|
|
o Calculate the direction of the cross
|
||
|
|
o Calculate the mean value of the two directions
|
||
|
|
o Set the motor speeds in order to head towards the mean direction
|
||
|
|
|
||
|
|
\b;The instruction \c;radar\n;
|
||
|
|
In order to detect a mine with the \c;\l;radar\u cbot\radar;\n;, we recommend the following parameters:
|
||
|
|
\c;\s; radar(Mine, 0, 180, 0, 5);\n;
|
||
|
|
With the opening angle of 180 degrees, mines that are behind the bot will not be found. Mines that are at more than 5 meters are also ignored.
|
||
|
|
|
||
|
|
In order to find a blue cross, simply write:
|
||
|
|
\c;\s; radar(WayPoint);\n;
|
||
|
|
Blue crosses will be found everywhere.
|
||
|
|
|
||
|
|
In order to calculate a direction, use \c;\l;direction\u cbot\direct;\n;.
|
||
|
|
In order to set the motor speeds, use \c;\l;motor\u cbot\motor;\n;.
