do you have some type of motor controller?

No motor controller. The servos are wired directly with arduino. The power is done by 5x1.2V batteries.

Looks good!

I think, that if you have the servo turn a bit slower, it will be more accurate in it's readings, making less false turns

Do you know a method to control the servos speed? interesting!

Yeah a for loop works. This is just a little example I wrote for you. It will show you how to slow the servo so you can write something similar for your bot.


void loop(){

servo.write(0);  //move the servo to the angle 0

delay(700);      // wait for the servo to move to angle 0

for( int x=0; x<=180; x++){   // This will loop 180 times

servo.write(x);            //set the servo to angle x

delay(10); // play with this delay value that will slow the servo

Thanks, but I already use this program structure (http://robottini.altervista.org/robot-with-obstacle-avoidances/)


 for (ang=0; ang<180; ang +=5) // obstacles control
              uservo.write(ang); // set ultrasonic sensor on ang value
              urm.requestMeasurement(DISTANCE); //ask for new reading
