Go to Post So perhaps those that are so eager to complain might realize that if they spent a little less time complaining and a little more time analyzing the problem and developing solutions, then they might have a little less to complain about. - dlavery [more]

The robot code does not run as a real time process. Nor does the standard JRE have real time support.

(That being said, I don't think C/C++ programs run as real time processes by default either.)
