Would anyone be willing to help a group of first time EV3 programmers figure out why our robot gets out of whack and wont follow the program we created? Sometimes it works fine but often times it makes an extra turn. Watch the videos in this link, one of them shows it doing it right and the other shows it making two 90 degree turns without going straight. The EV3 program is in the folder at this link too. Thanks for your help!
