I just wrote a program and I can't get it to work. I download it to the RCX
and it just runs its motors. I look at the display and push on the bumper
and it has those little triagles. So it is not hardware because the RCX
reads that the bumper in pushed. I need help! here is the program
#define go_straight() Fwd(OUT_A+OUT_C);
#define back_up() Rev(OUT_A+OUT_C);Wait(75);Fwd(OUT_A+OUT_C);
#define turn_left() Rev(OUT_A);Wait(Random(50));Fwd(OUT_A);
#define turn_right() Rev(OUT_C);Wait(Random(50));Fwd(OUT_C);
int last_value; // Used for IR proximiy sensing
task main()
{
start_up(); //Used to set up the sensors and tasks
while(true); //A repeat forever loop
{
bumper_check(); //Checks bumpers for collisions and turns
ir_check(); //IR proximiy sensing
}
}
void start_up()
{
SetSensor(SENSOR_1,SENSOR_TOUCH);
SetSensor(SENSOR_2,SENSOR_LIGHT);
SetSensorMode(SENSOR_2,SENSOR_MODE_RAW);
SetSensor(SENSOR_3,SENSOR_TOUCH);
On(OUT_A+OUT_C); //Turns on the motors to go straight
start send_ir; //Starts the task that sends out IR light
}
void bumper_check()
{
if(SENSOR_1 == 1) //Checks for left bumper
{
back_up();
turn_right();
go_straight();
}
if(SENSOR_3 == 1) //Then checks for right bumper
{
back_up();
turn_left();
go_straight();
}
}
void ir_check()
{
last_value = SENSOR_2; //Stores the value of the light sensor
if(SENSOR_2 <= last_value - 75) //Checks for a high fluctuation in light
{
turn_right(); //turns
go_straight();
}
}
task send_ir() //sends out a bunch of signal 20 times a second
{
while(true)
{
SendMessage(0);
Wait(5);
}
}
