    Aligning your fruit ‘n veg If you’ve ever had to output anything on the screen in ROBOTC, you’ve probably used nxtDisplayTextLine() or one of its many siblings.  Your code may, or may not have looked something like this: task main() { int num_apples = 10; // how do you like [...]

    For about two weeks there was  a bit of a scare, while the FIRST folks were deciding whether or not my Driver Suite was actually legal to use in the FTC.  It had been used for years prior to someone actually asking the question.  Their initial reaction was “no”, but [...]
