I am trying to control a ball grabber robot using NXT 1. My goal is to have the robot facing the same direction before searching for the second ball. The program I am testing with almost gets the robot back to the starting position, but not quite. The reason I am doing this is to take the balls to a drop off location. The code attached is just to test with, not the full program. It does not grab any balls.
Yes, this is the correct forum for NXT questions, although you may want to consider posting here as well (http://messageboards.lego.com/en-US/showforum.aspx?ForumID=1042.) Thank you for providing screenshots of your code, but it is a little difficult to determine what it does without notation; would you be able to provide the program for us look at directly? It would also help a lot if you could describe how you are getting the robot to move and return to the same position (e.g. motor on timing, motor position, sensor-determined location, etc.) as well as what you mean by "almost gets the robot back"- what sort of positional shift are you seeing?
