how can i make 50$ robot with sharp IR stop when 10cm from target?

[ballbreaker]

what are the commands? also how can i make it to stop and turn away when facing wall (doesn't have to follow objects.)

Heh. That's what I'm doing now.

well any tips?

It should be as simple as finding the sharp's output at 10cm and then use that as your threshold value.

will this work to follow an object and when its too close to turn?

   while(1)
      {
      scan();
      
      //object on left
      if(scan_angle > 57 && sharp_IR_reading > scan_thresh)
         robot_turn_left();

      //object on right
      else if(scan_angle < 41 && sharp_IR_reading > scan_thresh)
         robot_turn_right();
   
       // object at close distance
      else if(sharp_IR_reading == scan_thresh)
          robot_turn_left();
        
            
      //object is centered
   else if(sharp_IR_reading > scan_thresh && scan_angle >41 <57)
      robot_go_straight();
         
delay_cycles(400);

}

can anyone find any errors or if this would work as an idea?
