The video is almost useful, but not really, and here’s why.
A useful video would have the robot at stop, you should here the 5 second countdown beeps. Then the robot should move. That would give us is a first hand view of the starting process. I could for example know if the robot ever did go forward… Do you have a description of the real ring the bots will be using? Where is the competition and do they have a website? The bot appears to be “seeing” the line everywhere. The ground is not dark enough. The concrete appears to be shiny in places and that could be one of the reasons. The distance the line sensor is from the ground will effect how well it works. The angle the sensor is to the ground is important as well. It’s best to align the sensor to 45° to the ground. So, the bot is “seeing” the line too often. The line sensor has an LED on it to help you set it up properly. In fact you can move the bot manually and look at the LED to see for yourself how it is detecting the line when it is not there.
Yea the oil slick plugged a sencer I have sence cleaned and retested, its ok!! and it does go backwards, it should charge forward, it is being taken care of as I type, Its kinda hard to clear out a working repair shop to do this work, We are going to weigh-in tonite at 4:45 and then back to programming, we cannot tilt the sencer due to the size limitations 24x24x24 inches, it does respond to the sencers and changes direction thats what the tests were for. I concider it passing. now we need the update the code to turn on both rear line sencers 2 IR Sharpe sencers and a ping))) dead center in the front. test and tune is Thursday, eliminations are Friday and Finals are Saturday I am out of time.
I seen that before we checked it and it all turns free, We switched the drives and it does the same thing going the other way, we are hopeing new coding will take care of it, I call it moon walking!! Thanks for the input, the boys are working really hard on it!

There is no magic code that will fix your unknown problem. From the information I have been able to pry from you it has never been tested on a flat black surface, and I do not believe you even know if it goes forward after the 5 second delay. You told me it was, then you told me later you had to change them… In order for me to be able to do any good here, I need to be able to ask you to do something, see the results, then provide additional information. I have tried to get the dialog going, but your infrequent visits and your unwillingness to type long informative posts has made it impossible to help. I have asked so many questions that have gone unanswered…
Put the robot up on blocks so it can’t move. Turn it on and observe the wheels rotating. Do the wheels move in the proper direction to move the robot forward?
Place a white paper under the left sensor. The bot should back up, turn in place to the right, then start moving forward again.

Video the above scenario and report back.
Make no mistake, it’s NOT working properly and we need to find out why. We are in troubleshooting mode here.
You don’t need two troubleshooters, but simply programming a straight run across the floor, then a 180 degree turn and return would demonstrate a lot (or not).
