Tue, 30 Nov 1999 00:11:00 EST en-us Copyright: (C) RoboRealm, http://www.RoboRealm.com/ http://www.RoboRealm.com/ I am just learning how to use LEGO mindstorms. I am trying to keep my robot in a black circle until it sees red. When it sees black i want it to stop, make a sound and reverse then change direction and keep going. If it sees red i want it to make a different sound and then stop. Please look at the program below and tell me if i am using my commands right. I really need help on this and as soon as i run the program it jerks forward until i stop it. Thank you for your help.<p><a target=_blank href="http://www.roborealm.com/uploads/20973_1.JPG"><img border=1 src="http://www.roborealm.com/uploads/20973_thumb_1.jpg"></a>&nbsp;<br> http://www.roborealm.com/forum/index.php?thread_id=3695 http://www.roborealm.com/forum/index.php?thread_id=3695 Tue, 30 Nov 1999 00:11:00 EST
