Tue, 30 Nov 1999 00:11:00 EST en-us Copyright: (C) RoboRealm, http://www.RoboRealm.com/ http://www.RoboRealm.com/ I am a student that is learning how to use LEGO mindstorms. We are trying to keep my robot in a black circle until it sees red. When it sees the black line i want it to make a sound then reverse and change directions. If it sees red we want it to make a different sound and stop. Whenever i run the program displayed below, it constantly jerks forward until i stop it. I am not sure what i am doing wrong, am i using the commands the right way? I would really like help on this please, Thank you. http://www.roborealm.com/forum/index.php?thread_id=3694 http://www.roborealm.com/forum/index.php?thread_id=3694 Tue, 30 Nov 1999 00:11:00 EST
